# Kai Lukas Marquardt > Software developer building local-first AI integrations, high-performance systems, and privacy-conscious software with Rust and TypeScript. ## Profile - Website: https://kaimdt.dev - GitHub: https://github.com/kaimdt - Focus: local AI, Rust, TypeScript, system design, homelab infrastructure, and developer experience. - Philosophy: keep private context on the device when possible; use cloud services deliberately. ## Main pages - [Interactive portfolio](https://kaimdt.dev/) - [Blog](https://kaimdt.dev/blog) - [Experiments](https://kaimdt.dev/experiments) - [Public PGP key](https://kaimdt.dev/pgp) ## Articles - [Local AI without pretending the cloud does not exist](https://kaimdt.dev/blog/local-ai-without-the-cloud-tax): A practical boundary between private work on the device and the parts a cloud service is genuinely good at. - [Where Rust earns its place in a TypeScript application](https://kaimdt.dev/blog/rust-at-the-edge-of-a-typescript-app): I do not reach for Rust everywhere. I use it where a smaller, stricter boundary pays for itself. - [Why I keep a technical notebook](https://kaimdt.dev/blog/welcome): A small place for the details that are easy to forget once a project finally works. - [The boring parts are what make software scale](https://kaimdt.dev/blog/scalable-applications): Scaling usually starts with clearer boundaries and better measurements, not a larger infrastructure diagram. ## Feed - RSS: https://kaimdt.dev/rss.xml
