Full-Stack Engineer · AI-Native

Building Reliable AI Systems

15+ years of full-stack engineering. I've worked on advertising systems at Amazon and financial infrastructure at Stripe, where reliability and performance matter.

Now I'm focused on building agentic AI systems with the same care: solid integrations, dependable reliability, thoughtful UX. AI as foundation, not an add-on.

Committed to engineering excellence and AI that meaningfully complements product experiences.
