00About
Senior software engineer with 10+ years building production systems across consumer scale, aerospace, and defense. I design the architecture, build the backend, wire the integrations, and automate everything that shouldn't be done by hand.
My foundation is high-reliability engineering — subsystem test automation and hardware-software integration at Lockheed Martin and Space Systems Loral, where failure isn't an option. Today I build backend services and internal tooling at Google, and ship full-stack products, AI features, and automation for teams that need software done right.
