About Me

I'm Vice President of Engineering at FP Complete, and the founder and lead developer of multiple Haskell open source projects, including Yesod, Conduit, Stack, and Stackage. My focus is creating developer-friendly, high-performance libraries that improve software quality. I specialize in using Haskell, Rust, and modern DevOps to help projects make it to market faster, with fewer bugs. I regularly speak about programming best practices and write articles and tutorials on programming and health.

I live in Maalot, Israel with my wife Miriam and our six kids.
