At Semantic Health, I led full stack delivery for an enterprise healthcare SaaS platform, from React and Next.js interfaces to NestJS and FastAPI services on AWS. I shipped production document automation, semantic search, and AI assistants using OpenAI APIs and LangChain.

I built the RAG retrieval layer and tuned retrieval quality and response latency. I also cut API response and page load times by roughly 35% through caching, PostgreSQL query tuning, and frontend optimizations, while mentoring engineers through code review and pairing.
