Background
What I'm building
I build developer tools, AI-native interfaces, and things that bridge the gap between how people think and how machines read. Dewey came out of watching coding assistants struggle with real-world codebases — not because the models are bad, but because the docs are.
I also make Talkie (voice-first capture for developers), and a lot of other things — declarative design systems, spatial note-taking agents, programmatic video tooling. I believe typing is a bottleneck and that the best tools meet you where you are.
