Software engineer building peer-to-peer applications (Nostr / Bitcoin) in my free time.
Peer-to-peer accommodation marketplace using Nostr. The repo pulls together a Flutter client, Dart SDK and CLI, custom Nostr event models, escrow services via Cashu and EVM, AI/MCP automation, Terraform infrastructure, and Dockerized local services for relay, Blossom, EVM, and observability.
Hackathon project NIP-29 spatial-office prototype for Nostr groups. It combines React, TypeScript, Phaser, NIP-07/NIP-46 login paths, NIP-42 relay auth, encrypted session storage, deterministic shared maps, ephemeral presence events, and WebRTC call-grid experiments.
Nostr Markets Development Kit: a reproducible workspace for marketplace protocol work. It aggregates protocol drafts, Nostr runtime branches, demo clients, Cashu and EVM escrow drivers, regtest Lightning/EVM/Cashu stacks, scripted test/capture flows, and local HTTPS development infrastructure.
