kekofigueroa-dev/README.md

My real name is Sergio (AKA Keko)

TechOps Data Analyst @ Stripe. Back-end/Data/AI. Python · SQL · Linux.

I build systems that are meant to survive contact with reality: messy data, retries, incidents, and money moving through third parties. I’m allergic to “clever” solutions that can’t be reproduced—give me verifiable steps, good logs, and pipelines that don’t flinch.

What I work on

  • Detection + monitoring pipelines (risk/fraud/card testing signals)
  • Data-driven incident RCA (queries, dashboards, and “what actually happened?” tooling)
  • Automation that turns chaos into workflows (without magic)
