What I'm looking for

I'm looking to solve complex backend and distributed-systems challenges, modernize reliable financial platforms, improve software quality, and collaborate with multidisciplinary teams that share knowledge.

At CI&T, I build and modernize backend services, integrations, microservices, and BFFs for a major bank’s digital banking and investment portability platforms. I work end to end across technical refinement, implementation, testing, deployment, databases, and infrastructure.

I’ve led Java 8-to-17/21/25, Spring Boot 2.x-to-3.x/4.x, and Gradle 8-to-9 migrations, improving compatibility and build lifecycle consistency across multi-module services. Previously at EPD/VR, I modernized PHP and Java legacy systems, built ERP applications, and worked with Oracle, PostgreSQL, and MySQL.
