About
I’m Luis, a Site Reliability Engineer in Berlin. I care about systems that stay up, scale, and heal themselves, and about the decisions behind them: what they cost, how they perform, and whether they can be maintained.
What I do
- Reliability and platform engineering: Kubernetes (EKS, OpenShift, MicroK8s), Terraform/Terragrunt, GitLab CI, incident management and on-call design.
- Observability: Prometheus, Grafana, Loki, ELK, New Relic.
- Compliance in practice: I helped take a fintech through ISO 27001 from the platform side.
- AI infrastructure: LLM routing and serving, agents, and running inference on hardware I own.
- Languages: these days mostly Rust and Go, plus Python, TypeScript and a long stretch of Java.
