What I'm looking for

I’m looking for a backend engineering role where I can build async Python services with FastAPI, ship microservices safely, and apply hybrid retrieval + grounded LLM experiences for real search and AI Q&A impact.

I’m a Senior Software Engineer specializing in Python backend systems and microservices, focused on building async FastAPI services for search and AI Q&A. I design scalable systems that blend retrieval with generation to deliver accurate, grounded answers.

At AlphaSense, I led the migration to async FastAPI, reducing API latency by 30% while doubling throughput. At Hebbia, I built secure enterprise search and AI Q&A services, implementing hybrid retrieval with Azure AI Search and grounding responses via OpenAI and Gemini APIs.

I also bring strong delivery fundamentals—authentication/authorization with OAuth2 and OpenID Connect using Entra ID, plus CI/CD with GitHub Actions and Docker to cut release cycles by 40%. Earlier, I developed cloud-native backend platforms on AWS with Django, Django REST Framework, PostgreSQL, and event-driven microservices, with thorough testing using pytest and TDD.
