What I'm looking for

I'm seeking remote opportunities where I can contribute to global development teams.

At Vixteam, I contributed to industrial software for Usiminas and Arcelor Mittal, including real-time applications built with Quarkus or JAX-RS and Angular.

For the RGTE ironmaking slag system, I created an SVG map with D3.js from client-provided information. It connected with Kafka and WebSocket to support real-time updates as operators moved machines on the map.

I also helped replace a legacy SAP system by reverse engineering its logic and rebuilding it with Quarkus and Angular. I contributed to modernizing Vixteam’s Team Audit risk and compliance system with Spring Boot and Angular, addressing performance and usability expectations.
