I've led greenfield Java and Spring Boot architecture at TCE-MG and modernized legacy EJB systems into Spring Boot, improving transaction performance and reducing maintenance costs. I also implemented containerized solutions with Docker and Kubernetes, messaging integrations, and SQL tuning for executive reporting.
At VILT, supporting Porto Seguro, I delivered technical enablement and Java architecture learning paths focused on Spring Boot, JPA, and Clean Architecture. Earlier, I built highly available fintech checkout services with Spring Boot and PostgreSQL, customized TOTVS RM ERP modules in C#/.NET, and led telecom operations teams of up to 10 people at Oi.
