Staff Backend Engineer Rails Distributed Systems Applied AI Open Source

I build backend systems that scale without becoming harder to operate.

Specializing in high-performance Rails, distributed systems, and production AI infrastructure. No magic, just systems. I believe the best engineering decisions are those that eliminate operational complexity and remove layers of magic from software.
