About
Full-Stack Developer specializing in backend engineering with Node.js, TypeScript, and NestJS, building scalable, high-performance solutions across the entire development cycle.
Currently serving as Tech Lead at Singular Pharma, where I architected Compound360, a pharmacy management platform connecting 16 units across 3 northeastern Brazilian states, and am leading Prescreva+, a medical prescription platform with 600+ compound formulas and 500+ registered prescribers. I'm also driving the group's AI strategy, building RAG pipelines with LangChain and PgVector for semantic search, integrated via WhatsApp Business API.
Previously at Blue Saúde (healthtech), I owned the Document Analysis API, processing 1,000+ documents/day using Google Document AI and async queues. I started my dev career at Casa Serrana, where I taught myself to code and built automations that reduced default rates by 15%.
