Full Stack Developer
From breaking apart Rails monoliths into Kafka-driven microservices at Upstart, to shipping Chrome extensions and data tables at Seamless.AI, to building Filevine's F2 finance platform, I've spent the last decade making complex systems feel simple. I care about clean architecture, sharp craft, and shipping software people actually want to use.
