About
I'm a full-stack engineer, strongest on the backend (Node, TypeScript, NestJS, Go). I like getting into the business for real: sitting with the people who use the system, learning how the operation runs, and building for the result instead of the ticket.
At Singular Pharma I architected Compound360, a management platform connecting 16 units across 3 states in Northeast Brazil, and I lead Prescreva+, a medical prescription platform with 600+ compound formulas and 500+ registered prescribers. I also drive the group's AI work: RAG pipelines with LangChain and PgVector for semantic search, integrated over WhatsApp.
Before that, at Blue Saúde, I owned the Document Analysis API, 1,000+ documents a day with Google Document AI and async queues. I started at Casa Serrana, where I taught myself to code and built automations that cut default rates by 15%.

What I've been building
A sample of my recent work. The ones that took the most effort, and that I enjoyed most.
Pharmacy management platform that connects compounding pharmacies and their branches with real-time dashboards, sales tracking, production monitoring, and prescriber management. Replaces fragmented spreadsheets and manual reporting with a unified view across all units.
