I'm a full stack developer who moved from banking into software, with a background in Instrumentation Engineering. That shows in how I build: measure first, instrument everything, and make systems that fail safely.
Today I ship end-to-end products across web, mobile, backend and AI tooling, from a payments-grade booking platform to an MCP server that lets AI assistants query it.
| 🔭 Now building | ChessReview — an engine-powered chess game review app (going open source) · FD/RD Manager — an offline-first Android app (pre-release) |
| 🤖 Exploring | Model Context Protocol (MCP), agentic workflows with Claude Code, local LLMs with Ollama, ComfyUI |
| ⚡ Strengths | MERN · TypeScript · React Native · PostgreSQL · RBAC · payments · background jobs · automated reporting |
| 🎯 Goal | High-performance systems that solve real-world problems, with AI as a first-class interface |
Import your games, run Stockfish analysis through a background worker queue, and browse a move-by-move review.
- ⚙️ Architecture: Express API + BullMQ worker pool + Postgres + Redis, fully containerised with Docker Compose
- 🧠 Engine: Stockfish 19, run server-side in workers and in the browser (WASM build) for instant client-side analysis
- 🎨 Frontend: React 19, Tailwind CSS 4, shadcn/ui, with Lichess piece sets, board themes and opening (ECO) data
- 🔐 Backend hardening: JWT auth, Helmet, Redis-backed rate limiting, Zod validation, structured Pino logging
- 🌍 Plan: release under AGPL-3.0. The repo is currently private while I get it ready for open source.
React 19 Tailwind 4 Node 20 Express Prisma BullMQ Redis PostgreSQL Stockfish Docker
A complete, multi-surface product: customer web app, admin panel, REST API, mobile app, and an AI/MCP server, all sharing one backend.
