What I'm looking for

I'm looking to build impactful backend systems and APIs, improve operational processes through automation, and grow within teams using Java, Spring, microservices, and clean architecture.

At Grupo Gasômetro Madeiras, I maintain and evolve an Oracle-based ERP, optimize critical Java and PL/SQL routines, and build operational tools that reduce manual work. I delivered a Java AI-integrated HelpDesk triage system that cut manual demands by over 55%, plus automation that reduced shipping-map date corrections from 40 minutes to under 2 minutes.

I've also built data-driven backend services at Fabrízia Belo Consultoria, helping grow revenue by 900% through a shift to digital service. My projects include Pontex, an electronic health record and smart clinic queue built with Java, Spring Boot, WebSocket, SQL Server, MongoDB, and FastAPI, as well as a React and Spring Boot interactive quiz platform.
