I've built backend services for Assis's WhatsApp-integrated sales platform, including AI classifiers, product-action notifications, and end-to-end task, deal, and contact management. I work across Go, TypeScript, GraphQL, PostgreSQL, NATS, Kubernetes, Temporal, Stripe, and GitHub Actions.
As technical lead for Banestes's Pix team, I delivered regulated instant-payment capabilities including QR code flows, Automatic Pix, and Central Bank SPI integrations. I've also taught back-end development at Alura and built production full-stack products, including an AI-powered personal finance tracker on WhatsApp.
