About Jonas
I’m Jonas — a software engineer who likes turning messy, complex problems into full-stack systems. In my university projects I’ve been mixing machine learning with declarative logic, and professionally build and hosted full‑stack apps (Node.js, React, Svelte) and LLM setups.
On my website I’m self‑hosting projects, interests and looking for open‑source, less‑US‑centric alternatives to the defaults.
