Summary
🤩
Rockstar🎓
Top SchoolRafael De Campos Passos is a Staff Software Engineer based in São Paulo with 10 years of experience building data-driven backend systems, cloud infrastructure, and streaming platforms. He blends hands-on engineering in Go, Python, Rust and JavaScript with platform strategy—leading migrations to Kubernetes, cost-saving data-lake architectures, and production tracing and security (Cloudflare ZTNA). Rafael has a strong research background (visiting researcher roles and ongoing PhD) and brings that rigor to practical problems, from implementing ltree support in connector-x to improving resource cleanup in the git-bug project. He mentors and scales teams as a chapter lead while still delivering high-impact technical work, such as designing an async streaming service serving thousands of viewers and replacing Spark-based ETLs with cheaper, faster pipelines. Colleagues rely on him to translate complex requirements into observable, maintainable systems and to introduce new tooling and practices that stick.
