I like building things that work well — from AI-powered tooling to full-stack apps and system integrations. Helping teams ship great products, faster.

• 🏃 Strides — Couch to 5K, built for people who don't run yet. A private, science-backed run/walk coach: personalized plans, a run/walk timer with audio cues, and progress tracking. Expo / React Native · strides.legend.re
• 🩹 Rebound — Track how an injury feels, body and mind. A private, local-first recovery companion: a daily check-in, a 0–100 Body & Spirit Score, and a weather-style calendar. Expo / React Native · rebound.legend.re
• 🚂 zug — Search European trains from the command line. 8 providers (DB, Trenitalia, Renfe, SNCF, OBB, SBB, iRail, Rejseplanen), prices, MCP server for Claude.
• ✏️ inku — The cleanest markdown editor. Electron + CodeMirror 6 + React + SQLite.
• 💬 Loop — Self-hosted feedback widget for any web app. A floating button to capture a screenshot, annotate it (box, arrow, pin), and send — each report becomes a Linear issue. Framework-agnostic, shadow-DOM isolated, ~21 kB. Vanilla TypeScript.
• 🧰 skills — A toolbelt of agent skills for Claude: self-contained SKILL.md playbooks for niche, real-world procedures (DB Fahrgastrechte claims, Rundfunkbeitrag account changes), driven in the browser via Claude in Chrome.

• AI/LLM tooling — building intelligent integrations into real products
• Freelancing — helping companies ship faster and modernize their stacks
• Startup nerd — always down to talk about what's new in tech
