@rafaelcarv
Senior software engineer specializing in scalable full-stack systems.
BrazilWhat I'm looking for
I am a senior software engineer with extensive experience designing and building scalable full-stack systems using Ruby on Rails, Python, Java, and related technologies. I focus on delivering reliable, maintainable products and driving technical decisions that improve performance and developer productivity.
Throughout my career I have led migrations and optimizations—such as moving a CLI from Ruby to Crystal—implemented robust CI/CD and deployment workflows with Docker, AWS, Puppet and GitLab CI/CD, and contributed to distributed systems research and implementations. I regularly mentor peers, run design discussions, and raise code quality through thorough reviews and testing practices.
My background combines hands-on development, DevOps capabilities, and academic research in distributed systems, enabling me to contribute both to product delivery and long-term architectural strategy.
