I'm based in Germany. I write backend services in Go and ship frontends with TypeScript and React.

I use AI to optimize and orchestrate my development workflow — , , and — so architecture and product decisions stay mine.

Selected work

Personal site and writing — an editorial layout for projects, posts, and what I'm up to right now. Built with Next.js 16 and Keystatic, with typography and motion as first-class concerns.

Keystatic CMS for MDX posts with an in-browser editor.
Live Spotify now-playing on the home page; a /now page with Berlin local time.
Scroll reveals, reading progress, and glass navigation — all respecting reduced-motion preferences.
Deployed on Vercel with analytics; developed locally with Bun.

Anticheat systems that detect exploits and abnormal client behaviour.
Authentication with public/private key encryption — no native dependencies, pure Lua.
Modular inventory, jobs, and utilities with shared configuration and a clean event API.
MySQL-backed persistence for player state.
