Mechanical Engineer-in-Training
Jenmar Concepts
After graduating, I joined Jenmar, an engineering consulting firm focusing on hydrogen and alternative energy applications. My work spans custom hardware, thermal-fluid analysis, process controls, instrumentation, and field implementation. I also lead projects directly with clients, carrying them from kickoff through detailed design, commissioning, and closeout.

- Designed hydrogen cascade-fueling systems with temperature-compensated fill control for Underwater Autonomous Vehicles.
- Engineered hydrogen and oxygen heat exchangers using heat-duty calculations and NIST REFPROP real-fluid properties to meet thermal and flow requirements.
- Developed a hydrogen-blending installation for existing networks, evaluating blends up to 25% for pressure drop, flame behavior, gas dispersion, ventilation, hazardous-area classification, and low-ppm leak detection.
- Defined control systems, I/O, valve sequences, fail-safe states, and emergency-shutdown logic; selected transmitters, flow meters, and actuated valves for the required process conditions.
- Sized and selected regulators, relief devices, and other high-pressure components based on required flow capacity, pressure and temperature limits, set points, and failure modes.
- Led client kickoffs and design reviews, translated operating needs into requirements, and coordinated teams for multi-stage projects from FEED through detailed design, IFC, commissioning, and closeout.
