What I'm looking for

I'm looking to build scalable, reliable backend and distributed systems, with opportunities to work on concurrency, event-driven architecture, cloud infrastructure, and performance-focused engineering.

I've built backend services and event-driven systems with Go, Java, Kafka, and gRPC, with a focus on concurrency, scalability, reliability, and performance.

At Universidade Federal do Cariri, I reduced average deployment time by 20% through pipeline automation using Go, Docker, and GitHub Actions. I also designed an Apache Kafka event-driven architecture and migrated a legacy service to a Golang backend using asynchronous communication patterns.

I've contributed to SAP Ariba Category Management and built systems from scratch, including GoVoid, an in-memory NoSQL database in Go, and Cannon, a high-performance load testing tool in Rust. My projects also include a Java and Go financial ledger and Golang microservices for real-time text and video chat.
