Senior full-stack engineer based in Sweden. Building AI-native developer tools, on-device AI for mobile, and accessible OSS libraries.
I care about shipping software that does one thing well, doesn't trust the cloud by default, and stays kind to whoever inherits the codebase.
On-device AI for mobile: downloadable knowledge packs, local LLM inference, RAG without a backend. AI-native developer environments: multi-pane terminals with shared agent memory and MCP coordination. Accessible web components: small, focused libraries that solve one thing properly.
TypeScript · Rust · Go · Python · Swift · Kotlin · Flutter · React Native · Next.js · PostgreSQL · Tauri · Docker
Plus the agent layer: Claude, local Ollama, MCP servers, and whatever wires them together.
