Engineering leader at Kumojin who cut UseDrop's cloud and AI spend by 30%+ while improving reliability.

At Kumojin, I run an 18-person engineering organization, drive hiring and performance decisions, and led the adoption of AI coding agents across the org. I also stay hands-on, including event-driven architecture work for Prediko and Go backend code for Paren.

As fractional CTO for UseDrop, I own technical strategy, cost, reliability, and modernization for its multi-tenant SaaS. I cut AWS, Datadog, and OpenAI spend by 30%+, upgraded 12 projects, and set up SLOs and blameless postmortems.
