What I'm looking for

I seek senior engineering roles leading greenfield cloud/data platform projects—hands-on full-stack work, LLM/AI integration, product ownership, and a collaborative, fast-moving startup environment.

I am a senior software engineer with eight years building SaaS and data-driven cloud platforms using React/Next.js, Go, and Python. I turned zero-to-one ideas into products that drove 10x subscription growth, cut defects by 80%, and sustained 99.9% uptime through modern architecture and developer workflow improvements.

I've led greenfield full-stack teams to ship LLM-integrated dashboards, implemented point-in-time Postgres branching with Debezium, and modernized widget platforms to slim bundles 60% and reduce release bugs 82%. I now build Klay, a local-first wealth-management product, and seek roles where I can lead hands-on engineering teams focused on product impact and measurable outcomes.
