Gabriel Handford

I build full-stack products, developer tools, and agent infrastructure across web, backend, desktop, and mobile.

Currently at Instacart. Previously at Keybase and Yelp. I work across product surfaces and systems—from SwiftUI and web interfaces to Rust CLIs, Go services, and product backends—with a recurring interest in developer experience, security, and making complex systems feel simple.
