Hi, my name is
John Moorman.
I write software that pays for itself.
Software engineer in Berlin. I built an automation suite that saved a company €74K/year, letting two part-time administrators do the work of four. Now I ship AI-native software for clients, picking up whatever stack the project needs and delivering on tight timelines.

Open Source Projects
Things I built because I wanted them to exist. No client, no brief, every one of them shipped.
Diet-focused macro tracking app for a middle-aged and older audience. Natural-language meal entry as the headline feature. Built for Android and iOS with React Native.
Real-time browser multiplayer Skip-Bo with lobby, rooms, custom drag-and-drop, raw WebSocket server, and single-box AWS deploy.
Open-source, self-hosted text-to-speech reader with five swappable TTS engines, voice cloning, and offline PWA support.
Interactive multi-step wizard that calculates net salary, estimates living costs by Berlin district, and walks you through visa and admin steps. Angular frontend, Kotlin/Spring Boot backend, OpenAPI validation.
An open-source, self-hostable version of Drop with full model configurability: run it against local models via Ollama, or bring your own API keys for any provider.
This site, rebuilt from flat HTML to Next.js with an AI chatbot, MDX content pipeline, and streaming Anthropic integration. 95+ Lighthouse score.

10-in-10, Week 8: Skip-Bo Realtime Browser Game
A browser-native multiplayer Skip-Bo game with a pure-TypeScript engine, a from-scratch drag-and-drop stack, a raw-ws WebSocket server, and a single-box AWS deploy. Built deliberately without frameworks that would have abstracted the learning goals away.

10-in-10, Week 7: Young Artist Community
A directory and review platform for Young Artist Programs in classical music, built in 21.5 hours. The system design work I did before writing a single component is the reason it came together so quickly.
