Top SchoolCelso Martins is a software engineer based in São Paulo with 11 years of experience building and sustaining financial-services systems using Java (SE/8), Spring Boot/Batch, JavaServer Faces, Oracle SQL and CI/CD tools like Jenkins and Docker. He has moved from intern and junior support roles into core product development at Cartão Elo and now PagSeguro PagBank, combining incident response, process automation with feature delivery in DevOps-adopting teams. Comfortable in SAFe/Agile rituals and test-driven practices (Cucumber/Gherkin), he focuses on reliable integrations and operational maturity for payment products. His background in computer science and early teaching experience supporting computing classes hints at both strong fundamentals in algorithms/OOP and an ability to communicate technical concepts to non-specialists. He brings a pragmatic balance of sustaining production systems and introducing technical refinements to reduce debt and accelerate continuous delivery.
