I build AI-powered investment research tools at Arch Labs. Before that: chat design at LivePerson, experimentation tooling at Agoda, community systems at Answers.com, and a decade of building systems at HBO. This is where I write about product, code, puzzles, and fiction. There's nothing I enjoy more than brainstorming — if you have an interesting challenge to tackle, I'd love to hear about it.
