Kilian Weinzierl

Hey, I’m 21 and live in Regensburg, Germany.

I craft the surface. The part people see, hear, and interact with.

It should feel good, hold up in practice and look clean. Every element earning its place.

I work most days, and I design directly in code. No static mockups, no second version living in another tool.

I’ve started a handful of projects: iOS and macOS apps, web apps, a desktop app and some smaller tools. Mostly TypeScript and Swift, with Rust and Python where they fit.

I left BMW in 2026 to build my own things full time. One of them is Warning Room, a group chat that lists the (in my opinion) most relevant AI warnings, straight from the public statements of frontier AI teams.
