About

Senior Mechanical Maintenance Engineer with 20+ years of hands-on and leadership experience in the nuclear power sector. I specialize in ensuring the reliability of critical thermal-mechanical systems and coordinating large-scale maintenance campaigns at VVER-440 facilities. My expertise spans the entire lifecycle of safety-class equipment, including high-pressure pumps, heat exchangers, steam generators, and specialized HVAC systems. As Deputy Head of Maintenance, I lead cross-functional teams of 30+ specialists, bridging the gap between strategic outage planning and field execution. Key Expertise: • Outage & Maintenance Leadership: Led 15+ refueling outages with a focus on zero-incident safety culture. • System Reliability: Reduced unplanned downtime by 20% through optimized preventive maintenance and Root Cause Analysis (RCA). • International Standards: Guaranteed 100% compliance with IAEA and WANO safety and QA protocols. • Project Coordination: Managed procurement and technical documentation for complex modernization projects. I am deeply committed to global nuclear safety and operational excellence. Currently open to international opportunities (USA, Europe) in Maintenance Engineering, Outage Coordination, or Plant Operations. Ready for relocation and visa sponsorship.
