Hello, I am Lucas Barbosa Rocha 
.
Backend Developer with 4+ years of experience in Java, building REST APIs and microservices using Spring Boot and Quarkus.
Currently working as a Senior Developer, focused on system integrations and scalable cloud solutions using AWS and Apache Kafka. I also use Python for automation and have been exploring AI-assisted development workflows with tools like Cursor.
You can find my academic profile on Lattes and my ORCID is 0000-0002-9606-2569.
you can see my beewcrowd profile on beewcrowd (old URI).
Feel free to visit my personal Github and my academic Github profiles.
Beyond tech, I love animals and I’m an aspiring amateur cellist 🎻.
