At Globant on the Unity Technologies account, I designed and maintained Python, FastAPI, and PostgreSQL services for enterprise platforms, including external API ingestion and Gemini-powered workflows that cut executive reporting turnaround by about 80%.

I also built and sold a production loan and portfolio management system using FastAPI and Supabase/PostgreSQL. I lead Git-based pull-request reviews, model relational data, and build validated REST APIs with Pydantic.
