Summary
🎓
Top SchoolSergio A is a SecDevOps/SRE engineer based in Madrid with eight years of hands-on experience building and operating resilient infrastructure across Linux, CI/CD, container orchestration, and automation tooling. He has led DevOps/SRE teams and driven platform reliability at Making Science, and now focuses on SecDevOps and site reliability at Holafly while maintaining long-term operational responsibilities at Abastores. His background spans Debian/RHEL administration, Terraform and Ansible automation, Docker/Docker Swarm, reverse proxies and caching (nginx, HAProxy, Varnish), and monitoring stacks like ELK and Nagios. Comfortable across cloud-native and traditional environments, he blends sysadmin discipline with automation-first practices to reduce toil and improve observability. A practical problem-solver, he pairs formal technical training with a curiosity-driven, sometimes self-deprecating approach to continuous learning implied by his Github bio.
