Software engineer with 8+ years building high-throughput backend systems and APIs — most recently at DataStream Inc., where I led a monolith-to-microservices migration that cut deployment time by 60% and reduced p99 latency from 800ms to 210ms. I care about clean architecture, observable systems, and mentoring engineers who are earlier in their careers. Looking for a senior engineering role at a team that takes craft seriously.
