lbarrosby/README.md

Lucas Barros

Based in Rio de Janeiro. I design and operate Kubernetes platforms for teams that ship to production every day, mostly in financial services.

Over the last years that meant running a fleet of 330 clusters behind ArgoCD, Atlantis and Rancher, turning EKS provisioning from a two-day manual process into a 40-minute Terraform/Terragrunt pipeline, moving a 3,000 jobs/day Jenkins farm to immutable infrastructure, and treating cloud cost as an engineering metric rather than a finance report.

I care about boring, predictable infrastructure: everything in code, every change reviewed, upgrades that nobody notices.

Open source

Contributing upstream across the cloud native ecosystem: CNCF projects like Kubernetes, Envoy, Prometheus, Argo, Crossplane, Headlamp and CoreDNS, plus Terraform providers, Helm charts and AI infrastructure tooling (NVIDIA device plugin, Ray, deepwiki-open).
