About Jair Trejo

I am a Product Engineer who hates boring software. I thrive in the \"Founding Engineer\" gap—where systems need to be architected from scratch and shipped to millions of users without a roadmap.My Sweet Spot- Velocity: I once built a chess puzzle app in a single afternoon that hit #1 on Hacker News and was featured in Boing Boing- Scale: I’ve designed safety systems for 3B+ users at Meta and architected learning platforms for Amazon’s global workforce- Autonomy: I don\'t need tickets. I need a problem, a blank editor, and a team that trusts me to figure out the rest.Currently a Staff Engineer at Gusto. Previously L6 at Amazon, Senior at Meta & LinkedIn. I write code that solves human problems, from \"How does a knight move?\" to \"How do we keep Facebook safe?\"
