Engineering for systems that can't stop. Modernizing enterprise systems, connecting technologies and solving real-world problems.
I'm a Software Developer / Full Stack Developer focused on the development, modernization and integration of enterprise systems.
My strongest expertise is in Progress OpenEdge ABL and TOTVS Datasul, working with critical business processes, APIs, integrations and legacy modernization.
I also develop back-end solutions with Java and Spring Boot, and web interfaces using Angular, TypeScript and PO-UI, integrated with the TOTVS Datasul ecosystem.
My work sits at the intersection of business-critical legacy systems and modern software engineering.
