Professional Summary: Over 20 years of experience with GNU/Linux distributions and 10+ years delivering custom enterprise IT solutions. For the past 5 years, I have specialized in the architectural design, deployment, maintenance, and monitoring of on-premise infrastructures, managing complex networking and critical self-hosted services to ensure corporate data sovereignty. I approach every deployment not only from the software layer, but with a deep understanding of the underlying physical hardware and network topology. I have a proven track record of absolute long-term reliability and multiple client rehires, including over 1,200 hours on a single continuous contract. My technical and strategic focus prioritizes security, system resilience, and the automation of operational processes to minimize risk and optimize infrastructure costs.

Key Achievement: Disaster Recovery Under Extreme Conditions During the onset of the 2022 geopolitical crisis, a physical data center was trapped in an active conflict zone in Eastern Europe, facing an imminent risk of destruction without prior warning. I planned and remotely executed the emergency migration of the entire infrastructure to Hetzner cloud within 7 days, while the hardware was being dismantled on-site under the constant threat of bombardment. I improvised a temporary network topology and a high-availability cluster with minimal downtime. The Result: Zero loss of corporate data. Months later, after the hardware was extracted across international borders, I remotely coordinated the re-architecture, the physical hardware deployment, and the data repatriation to a new, secure data center within the European Union.
