Email is the surest way to reach me. I read everything, and I answer most of it. I'm in London, usually somewhere between an Xcode window and a document nobody asked me to write.
For anything at all: work, questions about Feat, or a talk you'd like me to give.
Short updates on what I'm working on, and the quickest route if you'd rather message than email.
Longer writing on iOS, testing and applied AI.
Side projects, experiments, and the occasional thing I open-sourced.
