What I'm looking for

I'm looking to apply my systems-level power experience to scalable, mission-critical infrastructure, particularly data center environments spanning utility interfaces through critical facility distribution.

I've engineered high-reliability power infrastructure for Kinectrics and NextEra Energy across commercial nuclear generation, spanning 120 VAC through 345 kV systems. My work covers critical AC/DC power, batteries, chargers, inverters, UPS, MV/HV distribution, large motors, protection, and contingency analysis.

At Kinectrics, I lead complex electrical design modifications, power-system studies, ETAP model development, equipment evaluations, and field implementation. I led an IEEE 1584-2018 arc-flash modernization, a safety-related 480 V MCC retrofit, and electrical scope for an approximately $2M instrument-air relocation supporting 4.16 kV compressors and 480 V auxiliary loads.

At NextEra Energy, I designed and analyzed high-, medium-, low-voltage, and DC systems, including temporary 13.8 kV distribution, safety-related 125 VDC alternate-source power, and critical cooling additions. I bring a systems-level power perspective to scalable data center infrastructure and reliability decisions.
