What I'm looking for

I’m looking to build user-facing AI products—LLM agents and RAG—end to end, partnering cross-functionally to deliver reliable performance, usable experiences, and measurable business impact through scalable cloud deployments.

I’m a Senior AI Product Engineer and full-stack engineer with 9+ years of experience building production-ready software systems, AI-powered applications, and scalable cloud platforms. I specialize in LLM applications, AI agents, RAG systems, and conversational AI, and I pair strong engineering expertise with product thinking to turn ideas into reliable AI solutions.

I’ve led multiple 0->1 efforts, including architecting and building an AI Healthcare Voice Agent Platform integrating with 80+ EHR systems to enable intelligent automation and scalable healthcare workflows. I also bring enterprise engineering experience from Google and Adobe, where I developed distributed systems and scalable solutions—and I stay focused on transforming emerging AI into dependable, real-world, user-facing products with measurable business impact.
