Projects

Check out my portfolio website to get details about my career journey including companies and industries I have worked for.

Helping founders stop hiring blindly and start hiring based on their demands so every euro goes toward execution, not mistakes.

A WordPress plugin that lets Claude, Cursor, ChatGPT and other AI agents safely run your site - posts, WooCommerce, SEO, images and more.

Registration-free group video calls - create a room, share the link, and talk face to face in seconds. Screen sharing and chat included.

Learn a language by doing nothing - ambient vocabulary that drifts by while you work, on desktop and mobile. 7 languages, fully offline.

A city guide for Berlin on a vintage treasure-map. See the landmarks, read their history, and save your favourites. Works offline. Coming soon to iOS & Android.

An open-source, AI first CMS you run from your AI assistant. Manage content, media and moderation from Claude Desktop, ChatGPT or any MCP client.

Realtime group chat with no sign-up - create a room, share the ID and password, and talk live over WebSockets. No accounts, no database, ephemeral by design.

A calendar-memories app - pin your photos to the days they happened, follow friends, and comment on and tag people in each other's moments. Built with React Native and AWS Amplify.

A 133-step, build-in-public path from an empty machine to a multi-cloud, Zero-Trust system, ending with 26 real big-company outages rebuilt in miniature. Build one real app with an AI coding agent and learn to defend the decisions.

Learn data structures and algorithms once and actually remember them. Each one taught from plain theory and the real place it runs, with an AI tutor that drills you until it sticks.

One canonical set of engineering practices for AI coding agents, loaded only when a task needs them. Works with Claude Code, Codex, Copilot, Cursor and Antigravity, plus a tool-agnostic test gate on git push.
