What I'm looking for

long term contract

At Solve With J, I deliver architecture, cloud transformation, modernization, quality engineering and AI initiatives for enterprise clients. My work spans healthcare, finance, education, transportation and data science across the USA, EU and Brazil.

For Certiverse, I led AI-assisted engineering with Claude, GitHub Copilot and Codex, accelerating delivery on a large-scale platform, and supported its migration to .NET 10. At RXSense, I supported benefit accumulator and copay systems in an AWS-hosted microservices architecture and contributed to a .NET migration.

At Listo Tecnologia, I restructured the Listo Fácil payment gateway from a monolith into distributed services. I owned pre-transaction processing, reconciliation and anti-fraud processes, and guided the team on transaction integration.

Earlier, at Case Imagine, I was lead backend developer for Job Manager, an event-management ERP with a global multi-language version, and its integrated portals WCase, ICase and The Perfect Staff. I’ve also modernized platforms, delivered cloud migrations and developed automated testing across a range of enterprise projects.
