About
Fullstack Software Engineer based in Salvador, Bahia, Brazil. Graduated from IFBA (Instituto Federal da Bahia) and coming from a graphic design background, I leverage my deep appreciation for visual arts and UI/UX to bridge engineering patterns with aesthetic details. I specialize in Angular, React/Next.js, Node.js, and NestJS, with a heavy focus on software architecture, AI engineering (including prompt engineering and RAG systems), and SQL/NoSQL databases like PostgreSQL and MongoDB. Passionate about modular codebases, containerized dev workflows, and delivering fast, context-aware web solutions.
