What I'm looking for

I'm looking for global B2B or independent-contract opportunities modernizing mission-critical systems, designing cloud-native architectures, and solving high-concurrency backend, API, and data-engineering challenges.

At Mobilize Financial Services, I lead modernization of transactional backend applications, moving Java 8/11 and Spring Boot 2.x systems to Java 17/21 and Spring Boot 3.5. I build and maintain microservices across AWS, EKS, Rancher, and Docker while supporting OpenBanking and OpenFinance integrations.

Across 25+ years in software engineering, I’ve built database-integrated code generators, modernized legacy web platforms, and transitioned monolith modules toward asynchronous Java, Node.js, GraphQL, and PostgreSQL architectures. At UTFPR, I led agile squads, governed APIs through Swagger/OpenAPI, and mentored junior developers and interns around Clean Code.

I also bring deep database, infrastructure, and legacy-system experience, including FirebirdSQL consulting, disaster recovery, performance tuning, Delphi migrations, and Linux systems operations. I’m an M.Sc. in Computer Science, a Firebird Developer’s Day speaker, and an open-source contributor publishing Svelte UI libraries.
