Senior software engineer specializing in Java microservices, delivering high-performance systems and faster APIs.
BrazilWhat I'm looking for
I’m a Software Engineer with 6+ years building scalable, high-performance distributed systems using Java (Spring Boot, Quarkus) and Angular. I focus on microservices architecture, REST APIs, and system integration, including performance optimization like eliminating N+1 patterns and reducing API response times from 3–5 minutes to ~20 seconds.
Across enterprise environments, I’ve delivered microservices for high-concurrency workloads (112K+ users) and integrated authentication/validation flows with gov.br for the CNH Social program (6K+ users). I also build reliability through automated testing (JUnit/JUnit + Mockito) and maintain CI/CD using Jenkins, YAML pipeline configuration, and Agile/Scrum collaboration.
