What I'm looking for

Busco oportunidades desafiadoras em backend e cloud onde eu possa aplicar Java, microservices e práticas ágeis para criar soluções escaláveis e impactantes.

Sou desenvolvedor backend sênior com mais de 16 anos de experiência em Java, atuando com microservices, Spring Boot e arquiteturas monolíticas. Trabalhei em projetos internacionais para empresas como Dell EMC, eBay e Lenovo, entregando soluções escaláveis e de alta qualidade.

Tenho forte experiência em ambientes de nuvem (PCF, Azure, AWS, GCP), bancos de dados (Oracle, PostgreSQL, SQL Server, MongoDB) e ferramentas de CI/CD e containerização como Jenkins, GitHub Actions, Docker e Kafka. Desde 2018 foco em Java 8+ (incluindo 11, 17 e 21) e práticas ágeis (Scrum, Kanban).

Sou um aprendiz apaixonado e jogador de equipe, com histórico de liderança técnica e colaboração em squads multidisciplinares; busco desafios onde possa aplicar minha expertise em microservices, cloud e automação para causar impacto significativo.
