Message

At Canindé, I built a POS and back office from scratch as the sole engineer; it’s now live at 6 restaurants. I designed the Go and PostgreSQL backend, shipped NFC-e issuing integrated with SEFAZ, and connected iFood orders and Pix/card payments.

At Azzz Smart City Innovations, I led a monolith-to-microservices migration in Go using Redis Streams and Saga-based consistency. Across my work, I’ve also built payment integrations, real-time systems, mobile apps, and production services with PostgreSQL, Docker, and Kubernetes.
