Reliable Linux System & Network Engineer – VPN, Pr

I am an experienced IT infrastructure and network administrator with a strong focus on Linux systems, virtualization, and secure networking solutions. Over the last three years, I have worked as the lead network and server administrator for a group of companies, where I was responsible for designing, implementing, and maintaining critical IT infrastructure.
My background combines formal education in electrical engineering and information technology (SPŠE Plzeň, 2020–2024) with hands-on, real-world experience. After continuing my studies at the Faculty of Applied Sciences at the University of West Bohemia, I decided to fully dedicate myself to professional IT practice, where I found the most value for both myself and my clients.
Core skills and expertise:

• Linux server administration (Debian/Ubuntu) – installation, configuration, security hardening, updates, automation.
• Virtualization with Proxmox – building and maintaining virtualized environments, high availability clusters, backup and restore strategies, efficient resource allocation.
• Networking & Security – routing, VLANs, firewalls, site-to-site VPNs, remote access VPN (OpenVPN, WireGuard, Strongswan/IPsec).
• Monitoring & Maintenance – proactive monitoring solutions to detect issues before users notice, log management, uptime optimization.
• Infrastructure design & deployment – from small office networks to multi-branch VPN-connected environments.

Experience highlights:

• Led the migration of legacy servers to Proxmox virtualized environments, reducing downtime and hardware costs while improving scalability.
• Designed and implemented secure VPN tunnels between multiple company branches, ensuring reliable remote access for employees.
• Built network segmentation (VLANs, firewalls) to separate internal departments, guest networks, and production environments, significantly increasing overall security.
• Introduced monitoring solutions that alerted IT staff before end-users noticed issues, helping minimize disruptions and maintain continuous service availability.
• Worked closely with teams and management to translate business needs into technical solutions that were cost-effective, scalable, and future-proof.

What I bring to clients:

• A problem-solving mindset – I don’t just implement tools, I deliver solutions tailored to the client’s real needs.
• Attention to security and reliability – ensuring data integrity and compliance with modern standards.
• Clear communication – I can explain technical details in a way that decision-makers and non-technical staff can understand.
• Flexibility – available for one-time projects, long-term support, or consulting.

Whether you need help with a one-time infrastructure project, an audit and improvement of your current environment, or an ongoing IT partner, I can deliver professional solutions based on proven experience and best practices.
