Beyond the storefront: double-entry accounting with automatic posting and bank reconciliation, rider dispatch for deliveries, a referral and reward-balance engine, a recommendation engine built on order history, retrieval-augmented product search, and self-hosted real-user monitoring with web vitals.
AI Employees — self-hosted multi-agent platform. AI agents are arranged as a company (CEO → departments → employees) and collaborate over the Model Context Protocol, with Markdown files as the cross-tree channel. NestJS and Prisma on PostgreSQL, LangGraph orchestration with a Postgres checkpointer, Redis-backed Socket.io, and a React front end with a Monaco editor and a node-graph view for watching agents work and chatting with them directly.
Earlier — as sole backend developer on a series of Flask products: a large-file transfer service handling transfers up to 40 GB, a cloud storage product with shared folders and per-member permissions, and a centralised log management system built on Elasticsearch. Also a Zoom-style video conferencing app on mediasoup WebRTC, and a React Native scheduling app.
Dummy Spice — a self-built demo, not client work. Most of what I build is under NDA and cannot be shown, so this exists to demonstrate the interaction and animation side directly: React and TypeScript with Framer Motion page transitions and product-card open/close, tuned so the mobile experience reads as a native app rather than a web page.
