About

IT professional focused on system administration, virtualization, and resilient infrastructure. I keep production environments stable, secure, and easy to scale through clear documentation, consistent monitoring, disciplined backups, and pragmatic automation.

~/documentation

Clear, current runbooks so systems are understandable — not tribal knowledge.

~/monitoring

Consistent visibility and alerting to catch issues before users do.

~/backup_dr

Disciplined, tested backups and recovery paths you can actually rely on.

~/automation

Pragmatic scripting to remove toil and keep changes repeatable.

// result
Faster, repeatable provisioning and fewer config-drift incidents.
LinuxRunbooksDocumentation

~/virtualization

Virtualization & Resource Optimization
