▍Summary

DevOps Engineer with 5+ years focused on infrastructure and 15+ years across IT, databases, and data platforms. At Wazuh, one of the world's largest open-source security platforms, I maintain the 6 public deployment repositories (Docker, Kubernetes, Puppet, Ansible, virtual machines, installation assistant) and coordinate release engineering across them — coordinating cross-repo version merges, changelogs, and LTS branches. I build and maintain CI/CD pipelines (Jenkins, GitHub Actions, AWS CodeBuild) for demo, training, and test environments, having shipped 1000+ PRs with a 93% merge rate. Experienced in AWS and Oracle Cloud, container orchestration, configuration management, and deep database expertise spanning Oracle, SQL Server, and data warehouse tuning on Exadata.
