Hey, I'm Sanjana 👋

ML engineer focused on building production-grade systems — multi-agent pipelines, LLM-powered apps, and MLOps infrastructure that actually ships.

MS in Data Science at Northeastern (GPA: 3.81) · Graduating Dec 2026 · Boston, MA


What I've Shipped

  • Multi-Agent AutoML — LangGraph system with 4 specialized subgraphs (classification, regression, clustering, feature engineering), supervisor + planner + memory agents, MCP-exposed tooling. Reduced project turnaround from 1 week to 3 hours. Used by real clients.
  • RAG Pipeline on GCP — Gemini 1.0 Pro + Pinecone hybrid retrieval, 71% → 86% answer relevance (RAGAS), deployed on Cloud Run at 500+ daily queries.
  • MLOps Demand Forecasting — XGBoost + Prophet with Optuna tuning, Airflow orchestration, DVC + GCS versioning, automatic rollback on regression. Full GCP deployment with MCP chatbot endpoint. Demoed at Google Cambridge.
  • Knowledge Graph Builder — LoRA fine-tuned LLaMA, GGUF + Llama.cpp local inference, Neo4j graph querying.

Experience

  • Machine Learning & GenAI Intern — Seagate Technology
  • ML Intern — Transformly AI, Boston (LangGraph multi-agent AutoML, MCP)
  • ML Intern — Fuzzy Cloud Inc. (RAG on GCP, Vertex AI, Gemini)

Open Source

Contributor to traceloop/openllmetry (LLM observability SDK) and abetlen/llama-cpp-python:

  • 🟢 [Merged] Fixed model metadata parsing in llama-cpp-python → PR #2217
  • ✅ [Approved, pending merge Fixed semconv-ai version bump for GenAICustomOperationName in openllmetry → PR #3826

Stack

LLM & Agents: LangGraph, LangChain, LlamaIndex, MCP, Pinecone, Vertex AI, Hugging Face
ML & MLOps: PyTorch, XGBoost, Scikit-learn, MLflow, Optuna, Airflow, DVC
Deployment: FastAPI, Docker, Cloud Run, GCS, Cloud SQL, GitHub Actions
Languages: Python, SQL, C++, Go


Wins

  • 🏆 Best Use of Public API — MLH Hackathon (1,614 participants): fine-tuned Xception for real-time pothole classification
  • 🏆 Best All-Girls Team — MLH Hackathon (501 participants): pose classifier using TF CNN across 7 pose classes

Currently Exploring
