EN PT

Senior Software engineer. Backend, Rust, Ruby, Python, Node, DevOps, infrastructure. Lately experimenting with agentic engineering — shipped a full-stack app for $2.96. I tend to believe the best code is the one you do not have to write.

Things I like

  • Polyglot backend development
  • Technical leadership and mentorship
  • Infrastructure, cloud, and DevOps
  • Agentic engineering and vibe coding
  • Niche frontend frameworks
  • Unix-based tools and systems
