Rockstar🎓
Top SchoolRanieri Junior is a Senior Software Developer based in Rio de Janeiro with a decade of experience building backend and mobile systems across startups and enterprise teams. He blends strong backend engineering—Node.js, Go, MySQL/MongoDB/DynamoDB—and cloud CI/CD automation with hands-on game development using Unreal Engine 5 and his own RanEngine, showcasing both production-grade services and creative real-time systems. At Zup Innovation and previously MadeiraMadeira and Compasso UOL, he led services deployed via Terraform and AWS Lambdas while maintaining a pragmatic full-stack background (TypeScript, Vue/Next, Python). Comfortable moving between backend infrastructure and gameplay programming, he brings a rare mix of scalable system design and low-level C++ engine work, plus a public project showcase on YouTube that highlights his self-driven craftsmanship.
