What I'm looking for

I am seeking senior-level roles in power generation or facilities maintenance where I can lead reliability-focused teams, oversee emergency power/HVAC systems, and apply hands-on diagnostics and project management to improve uptime and resilience.

I am an accomplished Mechanical Engineer with 30 years of hands-on experience in power generation, HVAC systems, and mission-critical data center operations. I have overseen installation, maintenance, and quality control of emergency power plants from 50 kW to 2 MW, supervised large generator fleets, and operated SCADA/BAS control systems across commercial and secured government sites.

My strengths include generator engine diagnosis and repair, HVAC commissioning and maintenance, team leadership in austere and high-security environments, and project ownership from commissioning to long-term maintenance. I hold multiple certifications in diesel and power plant systems and have consistently delivered reliable emergency power and environmental control solutions on complex, high-stakes projects.
