Gabriel Baldez

Java Backend Engineer · 6+ years · Brazil 🇧🇷

I build systems that scale — from REST APIs and microservices with Spring Boot to event-driven pipelines with Kafka and RabbitMQ. I care about scalable architecture, data governance, and making systems talk to each other. When I'm not in the backend, I'm building tools I actually want to use. I also love contributing to open source — giving back to the tools and frameworks I rely on every day.
