At Vale Telecom, I architected and maintained management platforms, delivery software, and backend modules. I also engineered banking integrations, including Sicoob services and real-time BolePix payments.
As a contractor at Vale Telecom, I developed backend features for Fala Ipatinga, the official Ipatinga City Hall municipal management platform. I built services with PHP and Laravel and worked on MySQL schema design and query optimization.
At Grupo Adriano Cobuccio, I developed financial systems with PHP, Laravel REST APIs, and React. I also extracted an INSS payroll loan system into an independent API microservice.
Across my other roles, I worked on CRM, consortium, e-commerce, healthcare, and ERP systems. My work included a PKI-compliant electronic signature module and an MVP architecture for real-time PIX payments.
