What I'm looking for

I seek senior engineering roles where I can lead frontend architecture and AI-enabled full‑stack projects, drive cloud-native modernization, mentor teams, and improve reliability and delivery.

I am a senior frontend-focused full‑stack engineer with 12+ years building AI-enabled, cloud-native, and distributed systems for enterprise, e-commerce, and healthcare platforms. I design scalable frontend architectures, reusable component systems, and backend microservices that handle millions of users and high-volume transactions while improving latency, reliability, and operational metrics.

I have delivered measurable results including AI RAG/LLM workflows that cut manual effort by 40%, observability and CI/CD improvements that reduced MTTR and deployment errors, and mentoring that accelerated delivery by roughly 30%. I take full production ownership and focus on performance, accessibility, and platform modernization across the stack.
