At Grupo Zaffari, I’ve worked on stabilizing and continuously improving a PCI-sensitive payment application for in-store e-commerce pickup orders, running on Gertec GPOS devices. I investigated production failures across the Flutter app, Android configuration, backend dependencies, local data handling, and device constraints; after a year of continuous improvements, the team reached zero reported incidents.
At CXD.dev, I’ve built and maintained Flutter applications for clients in areas including telecom, retail, e-commerce, and financial services, ranging from customer self-service apps to seller tools and white-label cloud storage products. I’ve also developed supporting tools for store operations and contributed to Meu Lar de Volta, a project helping organize cleaning efforts for families affected by the 2024 floods in Rio Grande do Sul.
