Backend-focused, currently freelancing while looking for a junior software engineering role in the Öresund region. I care about understanding every layer of what I ship: database, API, frontend, deployment.
Currently building production web applications on TypeScript/Fastify/Next.js/Prisma for clients. Reach for Go when concurrency or systems work is needed. Still love Ruby.
- p2pchat — full-mesh P2P chat in Go with UDP discovery, TCP connections, and concurrent goroutines. Built from first principles to understand how networking actually works.
- wclogs-cli — GraphQL API client in Go with OAuth2 auto-refresh. Discovered an undocumented field (extraAbilityGameID) through systematic curl exploration.
- stock-trading-simulator — Flask + PostgreSQL web app deployed to production. CS50 final project and the first thing I ever shipped to a real server for real users.
- weather-intelligence-system — Go + Python pipeline with cross-language JSON communication, containerized with Podman.
Professional client work is not public, but the blog covers the decisions and architecture.
