The main reader is an engineering leader or recruiter arriving from a resume, GitHub profile, referral, or search. They need to understand the role, inspect relevant systems, and reach the resume or contact links in one visit.
Three directions were considered: a restrained dark editorial portfolio, a light paper CV, and a product studio with large visual cards. The editorial direction preserves Zakhar's established black/cyan identity while making the career story and selected engineering work easy to scan. The paper direction is reserved for the downloadable resume. The product studio direction gave too much prominence to the number of projects.
The prior desktop and mobile captures showed an oversized sentence headline, duplicated navigation, a metrics dashboard, and action links below the first mobile viewport. The new composition has one horizontal header, name and role, one positioning sentence, visible resume and work actions, and selected work.
- Name, senior ML role, proposition, resume and selected work links. A quiet search field below the hero links accepts project names, problems, and technologies. Submission opens the existing archive and moves keyboard focus to its result count. Keep this secondary action to one compact row with 44px touch targets, capped at 440px; retain the navigation and primary action hierarchy. Exact names and aliases take precedence in results; related vocabulary ranks projects supported by the original query terms. Search covers affirmative case-study text, project-owned captions and source-reviewed capabilities; disclaimers stay visible without advertising excluded capabilities. Ordinary role and task vocabulary should find the same supported work as common acronyms. Prefer concrete, relevant engineering cases over general archives at the same match quality; generic word fragments must not count as technical matches. Preserve literal acronyms and honor the selected result order while a query is active. Rank inspectable implementations ahead of name-only listings for broad interests. Exact names improve rank without hiding other relevant work. Category totals describe current query matches, and filter recovery retains the visitor's query and order.
- A small curated selection of maintained products, ML infrastructure, and document/CV systems. Public links sit beside each story.
- Current and previous engineering experience, then approach and expertise.
- A clearly labeled, initially collapsed project archive for deeper exploration. Search actions and direct archive anchors open it; every existing route remains usable.
- Specific contribution records with visible PR status, updates, optional release counters, and direct contact. Issue participation is a separate disclosure.
Sections use whitespace and horizontal rules. Cards are for repeated projects and the project modal. Avoid nested dashboards, decorative grids, glows, generic AI art, skill meters, manufactured traction, and numeric portfolio totals in the hero. Keep existing project routes and keyboard interactions functional.
Use a stable type scale with explicit mobile breakpoints. The name is the only large display heading. Body copy is short, concrete, and set with a readable line length. Muted cyan identifies links and the role; off-white carries the primary content. No gradients or ambient decoration. Uppercase labels may use 0.1em tracking for a clear editorial section marker; body text uses zero.
Selected stories explain what the system does and Zakhar's engineering work. Prefer maintained service, package release, model deployment, and evaluation evidence over small audience counts or implementation item counts. Show no unverified performance claim. No internal review or sanitization language in the hiring narrative. Do not invent reviews or imply employer endorsement.
Preserve real screenshots at an inspectable size. Label generated conceptual diagrams as illustrations when displayed; do not turn them into product proof. For projects with no suitable screenshot, use a bespoke conceptual illustration that explains the subject. Label it visibly and keep it distinct from evidence. Use the existing multimodal-search, OCR and face-analysis system figures as composition references: concrete input, explicit processing stages and a recognizable output. Reject atmospheric still lifes, floating-paper metaphors and abstract model blocks. Keep labels short, purposeful and source-verified. Do not fabricate product dashboards, CLI commands or benchmark plots. Real research figures retain their axes, full captions, and evaluation limitations. Case studies show all selected figures in a responsive, inspectable gallery rather than reusing a title card as the only visual.
Selected cards lead with a readable HTML title and context label. A consistent framed figure follows as supporting material, with its source type in a readable caption below the image rather than a tiny overlay. Keep the selected stories; avoid making dense illustration text carry the card's meaning. Main case-study links navigate to a full reading page; archive cards retain the quick-view modal. Direct reading pages share the home page's typeface, identity and navigation.
Vehicle Lab follows the document and catalog stories as a released engineering notebook. Use the 01:22 exploded-inspection frame from its actual film, cropped to the CAD viewport, with a visible source caption. Keep its full film in the case-study links and archive viewer. The selected cards retain the ML career focus. Private company R&D uses brief experience summaries without project assets or implementation details. Vehicle Lab copy distinguishes released software and digital prototypes from physical assembly or driving, which remain unverified.
Open-source evidence groups contributions by project, ranked by practical impact and upstream acceptance. Each row pairs the project's GitHub logo with one short benefit, accurate merged/open counts and direct PR links. Neuralink leads with seven merged changes; substantial pending fixes follow before smaller documentation changes. Mark contributor-branch work explicitly. Keep bug reports in a disclosure. The hero includes an Open-source contributions button linking to this section.
The Vehicle Lab preview works because the subject remains large while its state changes. The older white workflow sheets and profiling table lose their detail at card size. Keep the page hierarchy and a small selection of projects; improve the figures rather than expanding the homepage into a gallery.
Three media directions were assessed: decorative studio art, full workflow diagrams, and short process sequences. Use process sequences for cards. Retain full diagrams and recorded reports in case studies. Generated art supplies a subject only; labels, geometry, numbers, and transitions come from the project.
- Dermaself: a synthetic face, guided capture, facial regions, and structured results. Label the sequence as an illustrated workflow, never a model result.
- Agnitra: animate the actual recorded tensor shapes layer by layer. Keep the package version visible and make no optimization or accuracy claim.
- Video retrieval: reveal the visual, speech, and OCR lanes, then timestamped retrieval. Use an authored illustrative scene and label it as a schematic.
- SectionCheck: use the released synthetic shapes and exact translation/ROI coordinates. Explain proposed mapping and review without implying approval.
Reserve new 3D models, films and GIFs for substantial main projects with a clear engineering story. Datarepo consists of small upstream contributions: retain its PR links in the contributions list and exclude it from the main catalogue and 3D galleries. Agnitra and Multimodal Video Search are the next selected batch; small patches and diagnostic notes do not receive standalone showcases.
Use 1280 × 720 sequences, an immediately informative poster, a restrained dark background, large subject and short labels. Prefer MP4 for on-page motion; GIF exports are optional sharing assets. Reuse the existing pause control, visibility suspension, reduced-motion and data-saving behavior. Captions must distinguish recorded output, synthetic fixtures, and conceptual illustrations.
Neuralink appears in contribution and independent-project contexts. Do not add it to employment history, employer logos, or imply affiliation. The five datarepo PRs #57, #58, #59, #67 and #68 are merged as checked on 17 September 2026. SectionCheck and AAC remain independent adjacent work with their own upstream and scope boundaries.
For substantial contributions with an inspectable example, link a focused lesson from its contribution row without promoting every patch into selected work. The September 2026 batch covers netCDF4 empty selections and pydicom LUT indexing. Each opens paused with a useful model, an explicit Play/Pause action, restart, scrubbing and chapter navigation. Input, camera and selection interactions pause the example. Reduced motion and a hidden tab stop playback. Keep arithmetic and shape explanations usable if WebGL cannot load.
Every scene answers a specific question through a real change in state. netCDF4 uses the PR's synthetic 3 × 5 × 7 shape; no cubes survive an empty selection. pydicom uses synthetic values and a four-entry LUT; height represents value, never anatomy. Keep dated PR status in the contribution listings and link source/tests from the lesson. Labs focus on the example and controls; omit contributor, acceptance and benchmark disclaimer blocks. Use short legends only where they help interpret the model. Use semantic colors, readable DOM explanations, keyboard equivalents for picking, and explicit source versus illustration boundaries. Separate text from the model viewport so smaller screens can scroll instead of hiding controls or shrinking type.
Considered directions: a film-only preview, an orbit-only scene, and a guided example with editable inputs. Use the third: the visitor should be able to pause at the failure, change the input, and understand the corrected result.
At 390px and 360px, name, role, positioning sentence, and both main actions must fit in the first viewport. At 768px, work cards form two columns where their copy remains readable. At desktop, the layout uses generous side margins and an intentional maximum width. No horizontal body scrolling or cropped text.
Use semantic headings, visible keyboard focus, 44px or larger main controls, understandable links, keyboard-operable project cards, and the existing modal focus trap. Respect reduced motion. Resume, GitHub, email, Telegram, LinkedIn, and X remain discoverable without a floating control obscuring the content.
Inspect before/after screenshots at 360, 390, 768, and 1440px. Run typecheck, build, repository validation/security checks, and relevant UI E2E tests. Release requires at least 8/10 in clarity, visual trust, evidence integrity, responsive polish, accessibility, claim alignment, action clarity, and uniqueness. Record the observed scores in the delivery report after screenshots.
Separate hidden artwork
The standalone Skill Wind page keeps its existing deep ink, copper, parchment, animated wind currents, and transformation artwork. It is a separate visual piece and does not dictate the portfolio layout. Preserve its reduced-motion behavior and the existing discreet header navigation gesture.
Retain the contribution-first page and its charcoal/cyan identity. The new reproject lesson compares actual two-pixel outputs from the upstream regression. Considered directions: a sky photograph, a flat coordinate diagram, and three linked coordinate planes with a guided numerical readout. Use the third; a sky photograph would obscure this linear WCS fixture. Added depth separates frames.
Keep play/pause, restart, seeking, chapters and manual pixel/version inspection. Use semantic HTML for every coordinate, decision, image value and footprint; the model supports the explanation and has a complete text fallback. Never plot an undefined inverse as a finite point. Keep the source PR and downloadable fixture/exporter beside the numerical explanation. Start paused and retain visible keyboard focus and 46px controls. Inspect 360, 390, 768 and 1440px.
The catalog service is currently paused. Its portfolio links lead to the available 3D guide and film. This availability supersedes the live-workspace links described in the earlier catalog design notes below.
Add Architectural Drawing and Interior Catalog Matching to the first selected-work row, following Document AI. It is an existing substantial project with recovered original catalog/elevation inputs. Retain the hero and all seven earlier selected stories. Use a compact silent preview in the repeated project layout; put the full interactive lab behind an explicit link.
Considered directions: (1) a photoreal room flythrough, (2) an abstract document/AI node graph, (3) a cabinet comparison driven by the original catalog. Select the third because the one-drawer/two-drawer difference explains exact matching with real evidence. A room flythrough would require unverified room geometry; the graph would obscure the item being matched.
The lab uses charcoal editorial framing, warm oak, porcelain carcasses and brushed dark hardware, with cyan dimension/evidence marks. Material finishes and construction details are authored. Product family, door/drawer counts, allowed nominal dimensions and catalog pages are source-grounded. Keep text outside the model on small screens. Use at least 44px controls, a readable no-WebGL fallback, paused entry, keyboard selection, chapter navigation and deterministic camera states.
First traffic: portfolio selected work and the architectural project case study. Reader: an engineering lead or design technologist examining source-grounded document AI. Share moment: opening two cabinets reveals why similar-looking codes cannot be treated as interchangeable. Action: explore the catalog comparison; download the film or model.
Seven media candidates were evaluated, each with an explicit privacy boundary (original client sheets remain local):
| Hook | Audience / proof | Incentive / CTA / share trigger | Decision |
|---|---|---|---|
| One code, one catalog family | Engineering lead; original B3000 callout and page 27 | Follow the match; open 3D; source-to-object reveal | Use as opening |
| One drawer or two? | Design technologist; catalog diagrams 27/28 | Compare B3000/B3100; open drawers; send the difference | Main film |
| Open the cabinet | Product designer; grounded shelf/door counts | Inspect internals; separate parts; save the exploded view | Use chapter |
| A code is not a dimension | Architect; allowed catalog options | Change width; inspect nominal configuration; share unit clarity | Use chapter |
| Catch an incorrect mapping | Document-AI engineer; W0100/R1000 source pages | Read corrected facts; source notes; share failure lesson | Use text evidence |
| From callouts to a draft BOM | Estimator; source/occurrence contract | Review unresolved quantities; case study; send review pattern | Use final chapter, no invented prices |
| Cinematic room flythrough | General visitor; no recovered verified room geometry | Walk a room; share finish concept | Defer; would invent room facts |
The initial release used six 5-second chapters at 24 fps, 1920×1080; the on-page loop is 1280×720. The complete eight-stage film below supersedes that timeline. Render a readable first frame/poster and VTT captions. The same procedural scene drives the playable lab and deterministic film. Verify source hashes, media metadata, responsive screenshots, fallback, controls and public leak gates; record critic scores after inspection.
The catalog card now leads to the working full workflow. Keep its playable 3D preview in selected work and the full film in the case-study hero; the final generated cabinet images belong in the inspectable case gallery. Label real agent output, source-grounded procedural geometry and proposed model evaluation distinctly. The full workflow uses original document crops and reviewed unknowns, rather than a fabricated dashboard.
Reuse the September 25 session's guided-example workflow: play/pause, restart, scrubbing, chapters and manual inspection. Considered placements: a blocking intro film, a standalone link, and an integrated preview. Use the integrated preview in the desktop current-work column, with a direct 3D Story link among the mobile hero links and another beside the catalog card. Retain the identity, resume and selected-work actions. Motion starts silently when visible, respects reduced motion and data saving, and stops when offscreen or user-paused.
The small preview shows the cabinets at useful scale; chapter text belongs in HTML and in the full film, rather than being shrunk into a card. Refine warm oak grain, metal reflections, contact shadows and smooth camera moves using the same deterministic procedural scene. Keep the geometry and selected nominal dimensions grounded in the original catalog. Studio lighting and materials are illustrative. Provide fullscreen for detailed inspection. Re-render the film, posters, preview and GLB together, preserving source and frame receipts.
If a browser denies native fullscreen, expand the scene within the page. Keep the controls usable, contain keyboard focus, and let Escape return to the same inspection state. Fit both cabinet families and opened components in portrait views; camera distance and orbit limits must adapt together. The downloadable GLB is explicitly the default 36-inch model, independent of live selections.
The film now follows all phases into a furnished room. Considered directions: full-screen document slides, an extended cabinet orbit, and a guided transition from real paper evidence to a physical room. Choose the third. Keep the original minimal document crops and recorded ImageGen output visibly separate from the authored 3D room. The room is an adjustable illustration, not a recovered site.
Eight chapters of eight seconds each use distinct visual actions: scan the original drawing; lift the code into an extraction record; connect the original catalog diagram to its family; open and separate the drawers/doors; align known facts and leave unresolved fields amber; reveal the recorded interior render; construct the room and slide the cabinet into a measured illustrative bay; retain that final room while assembling the reviewable handoff. Scrubbing must reproduce each state, including wall growth, cabinet position and fit marks.
| Hook | Audience / real proof | Incentive / CTA / share moment | Privacy boundary | Decision |
|---|---|---|---|---|
| Find the original callout | Architect; original drawing crop | Follow the scan; play the story; save the source-to-code reveal | Existing minimal public crop | Opening |
| A code becomes a record | Document-AI engineer; native page/coordinates | Inspect extraction; source notes; share mentions-versus-quantity distinction | Selected extraction fields only | Extraction |
| Diagram becomes cabinet | Design technologist; catalog p. 27/28 | Compare families; open 3D; send the one/two-drawer difference | Existing minimal public diagrams | Match |
| One drawer or two | Product designer; grounded family construction | Open/explode; select a part; save the exposed shelf view | Authored geometry labeled | Inspection |
| Keep unknowns visible | Estimator; reviewed known/pending fields | Change nominal width; read sources; share the review boundary | No invented quantity/price | Review |
| See the recorded result | Engineering lead; actual ImageGen outputs | Inspect the recorded render; open full workflow; share source-to-result contrast | Existing public concept images | Render |
| Will this cabinet fit? | Architect; nominal width and authored bay | Adjust the bay; inspect room; share clearance/shortfall response | Authored room and site unknown labeled | Room fit |
| Carry the result forward | Engineering lead; recorded review and exports | Keep final room; open full demo; share the recorded handoff | Reviewable export fields, no full raw sheets | Closing |
Room controls use millimetres for available bay width and the catalog's nominal inch width converted to millimetres. Report equal side clearance or the width shortfall; do not imply installation, door-swing clearance or fabrication approval. Keep the existing full functional demo linked for actual agent execution and artifacts. The film explains its recorded examples; it does not replay live jobs. Use warm plaster, oak, stone, window light and contact shadows for the room; cyan identifies source connections and bay guides, amber marks unresolved or non-fitting states. No synthetic document evidence or invented price/quantity.
The full 64-second film is 1920×1080 at 24 fps. The home preview retains the existing non-blocking placement and playback policies. Phase labels stay in HTML for small screens; the capture includes readable phase explanations and captions. Verify real asset hashes, all eight actual scene states, positive/negative fit, deterministic seeking, mobile framing, fullscreen fallback and keyboard controls.
Reserve separate, opaque rows for the model surface and its captions. Documentary boards, room edges and dimension guides must fit inside the model row with a visible margin. Text on a physical label uses a coplanar mesh and ordinary depth testing; it must never float through walls or outside its plate. Room placement and final handoff share one fixed room framing. Use restrained fades between chapter compositions, smooth object easing, and an uninterrupted room-to-result camera. Keep original documents and the recorded render intact.
A separate visual reviewer inspects decoded stage frames, chapter boundaries and the small preview. Automated composition checks cover the entire timeline and responsive views; stable GPU readback alone is insufficient for a visual pass. Retain defects and the revised review separately from earlier release records.
Use a teaching/workroom concept informed by the recovered elevation's casework context. Choose an adjoining millwork run over a solitary cabinet or an unrelated residential kitchen: two catalog-allowed 24-inch B3000 neighbors, an opening for the selected family, one continuous counter, upper storage, a worktable, chairs and a small courtyard beyond the window. The layout, neighbor quantity, other furniture and exterior are authored. Do not imply recovery of a measured site.
The default 914.4 mm opening exactly matches the 36-inch nominal cabinet. Other opening widths use visible symmetric infill or reject an oversized cabinet. Align the approach in front of the counter before inserting straight into the opening. An oversized cabinet stays in front with the opening visibly empty. Show actual geometry alignment, floor contact and numeric width/height/depth checks. Keep the selected oak cabinet dominant against quieter adjoining units. Retain stable framing and separate caption rows. Recheck both families, all nominal widths, exact/wider/narrower openings, responsive views and actual film.
The curated snapshot covers both public contributor accounts, including earlier merged mobile-inference, signature-bot and documentation work. Neuralink has seven merged PRs and the netCDF4 correction is merged. All public open or merged PRs found in the complete external-repository searches are represented. Personal repository avatars identify the contribution source alongside existing company logos; they do not indicate employment or endorsement. The GitHub profile keeps earlier small contributions in one native disclosure so recent ML work remains easy to scan. Its current experience and research descriptions match the portfolio.
Chrome statistics describe the observed public publisher-search page and only current detail-page rows with a visible count. The count of observed listings is not a complete developer-dashboard total. Unavailable counts are omitted from current totals; a failed source retains its previous dated snapshot.
