Security & Monitoring Implementation: Secured a budget for a new server and deployed a comprehensive monitoring system (Zabbix, SNMP) to oversee infrastructure. Enhanced security by configuring WireGuard tunnels and deploying VeraCrypt full-disk encryption.

Looking for
I am looking for a company with a trust-based, results-oriented culture that respects a healthy work-life balance. I appreciate the flexibility to manage my own time and the opportunity for a self-directed professional development.
I'm not considering opportunities in the military-tech or government sectors. A dedicated parking space would be a great benefit.
