Hi, I'm Rafael — Platform & Backend Engineer

20+ years designing and building the systems other developers rely on to ship.

Working with: Rust, TypeScript, Kotlin, Java · Kubernetes, AWS, Terraform · Distributed Systems

What I do:

  • Internal frameworks and platform tooling
  • Polyglot system design (Rust ↔ TypeScript ↔ Java/Kotlin)
  • Systems-level performance and reliability

Recent work:

  • Led Node.js → Rust migration of production customer-facing services (~15 services)
  • Architected self-managed Kubernetes consolidation on AWS — 50% cost reduction, 14→3 AWS accounts
  • Designed telemetry ingestion platform for Brazil's Open Finance ecosystem
  • Built the Vivere Framework — internal application platform deployed across 6 major banks, zero per-tenant code changes

Outside of code: musician, motorcycle traveler, maker and 3D printing enthusiast.
