Developer from the Netherlands 🇳🇱 · local-first apps, terminal tools and small AI models that run on your own machine
- 🔒 I like software that keeps your files, photos, voice and searches on your own computer
- ⌨️ I write terminal tools in Go and Rust, and web apps in TypeScript
- 🤖 I fine-tune and quantize small vision-language models to run locally (MLX, GGUF, llama.cpp)
- 🪟 Soft spot for retro interfaces: Windows 98, 8-bit, turntables, liquid glass
- 🐕 Many projects star Spot, a black labrador My portfolio has a website, terminal and Windows 98 view, with a docs page for each project.
