Overview
As a SysAdmin at Cognativ, I support Linux and hybrid infrastructure across Microsoft Azure and on-premises Proxmox environments. My work focuses on reliable software delivery, infrastructure operations, production troubleshooting, and close collaboration with development and support teams.
Key Responsibilities and Achievements
- Configured, deployed, and maintained self-hosted Gitea and act runners for on-premises and hybrid development workflows, improving job execution speed and infrastructure integration.
- Planned and implemented resilient CI/CD workflows for multi-environment deployments, improving build control and reducing dependency on external automation services.
- Managed hybrid Azure and Proxmox environments, coordinating virtual machines, networking, storage, access policies, and workload placement.
- Administered and tuned production databases, including backups, performance optimization, user access control, replication support, and routine maintenance.
- Troubleshot application failures, deployment issues, and infrastructure incidents to maintain service continuity and reduce downtime.
- Collaborated with developers and support teams to streamline releases and resolve environment-specific issues across hybrid infrastructure.
- Executed operational SOPs and runbooks for service restarts, credential rotation, failover checks, and standard diagnostics across Debian and Nix-based Linux systems.
