Senior software engineer at McKinsey who built Azure OpenAI and RAG features for client-facing tools.

At McKinsey & Company, I took a client analytics reporting feature from a rough problem statement to launch, owning its Postgres schema, Node and TypeScript API, and React interface. I also integrated Azure OpenAI into client-facing tools and built a retrieval-augmented feature over client document corpora.

At RVO Health, I owned APIs for Healthline, Medical News Today, Greatist, and Psych Central, and cut p95 latency from 620ms to 180ms. Earlier, I built booking, pricing, and advertising platform features at Evolve and VidMob.
