Senior Eng + Former Founder

Hi! I’m Yasyf. I’ve spent my entire life building: software, teams, and companies. You can throw me at any problem and I’ll make progress.

My interests are in developer tooling (I built a security x devtools company), open-source frameworks (I was a Rails contributor), and language design/compilers (I taught MIT’s grad compilers class).

My eternal love is Ruby, but recently I’ve been building a better Google Flights in Elixir to check out what all the hype is about.

My ideal role is heavily technical, while taking advantage of my background as a product leader and executive.
