I build reliable cloud platforms, Kubernetes delivery, and AI infrastructure at scale.
SpainWhat I'm looking for
At KRAM, I design and operate production CI/CD pipelines for cloud-native, Kubernetes, and AI workloads using GitHub Actions, GitLab CI/CD, and Argo CD. I build reusable Terraform, Ansible, CloudFormation, and AWS CDK modules across AWS, Azure, and multi-cloud foundations.
I reduced time-to-root-cause by 35% through Python and Bash diagnostics for Linux, container, and Kubernetes node failures, supported by runbooks and automated remediation. My work also extends into MLOps and Generative AI/RAG workflows on AWS Bedrock, covering secure model access, IAM, secrets, monitoring, cost controls, and release governance.
Previously at Comunica Telecomunicaciones, I migrated OpenShift 3.11 to multi-AZ OpenShift 4.10 on AWS with zero unplanned downtime. I increased release frequency by 300% with Argo CD ApplicationSets and GitOps delivery, reduced change-failure rate to 2%, and cut critical CVE exposure from 14 days to 48 hours.
Across Lemonvil and Telfy Telecom, I improved uptime, lowered infrastructure costs, automated Linux and OSS operations, and built observability practices with Prometheus and Grafana. I enjoy enabling engineering teams to ship faster without sacrificing stability, security, or operational clarity.
