Acerca de Kai
I ship software end-to-end, from idea to deployed product. Recent work: a paid macOS menu bar app distributed to university students (Python, Playwright, Lemon Squeezy payments, code-signed .dmg, Netlify) and an iOS social driving app built solo in React Native and TypeScript (~44k lines, Supabase Realtime, App Store pipeline). I handle the full stack: backend automation, browser scraping, mobile frontends, payments integration, and deployment. Native German and English speaker, useful if you need someone who communicates clearly across the DACH market. Available for automation scripts, macOS/iOS apps, backend integrations, and AI tooling.
