I'm a software engineer with 10 years of experience in software development. I've designed and built solutions as an entrepreneur, as a consultant, IC and lead engineer in companies big and small. I have a knack for backend development and strong product management intuition.
10+ years building distributed systems at Uber, DoorDash, and Jobscan. At Uber, rebuilt cadenceworkflow.io docs and consulted 50+ teams on workflow orchestration (12B+ workflows/month). Currently building Minarete - shipping soon.
Seattle-based, open to FAANG/growth-stage startups (Series B+) in infrastructure, developer platforms, or applied ML. EM or senior IC roles.
