Hey, I'm Gabriel 👋

Lead Engineer @ Lerian — building the platform that powers our fintech.


🔭 What I'm up to

  • Leading the Infra-Tools team at Lerian — the internal platform that powers every other application in the company, including the high-throughput ledger running our core fintech operations.
  • Building the foundations other engineers build on top of: IAM (OAuth2/OIDC), observability, and software licensing services.
  • ~10 years in backend. I care about reliable platforms, great DX, and shipping code that scales without overengineering. Big on pragmatic engineering, clean architecture, and TDD.
