What I'm looking for

I'm looking for sysadmin, infrastructure DevOps, or defensive security work where I can operate and harden Linux, cloud, and network environments, investigate incidents, and contribute remotely or on-site in an international setting.

I've administered Linux servers, VMware virtual machines, Docker Compose applications, PostgreSQL databases, and GitLab EE for a public-sector government contractor in Bogotá. I led a migration of approximately 376 GitLab projects from AlmaLinux to Ubuntu Server and maintained monitoring, TLS certificates, and centralized authentication.

I've investigated a compromised GCP VM, tracing Behinder C2 webshells, privilege-escalation logic, and hidden database users before leading remediation and credential rotation. I'm targeting systems administration, infrastructure DevOps, and defensive security roles in international remote or on-site environments.
