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.

- Developed a hydrogen cascade fueling system with temperature-compensated fill control for Underwater Autonomous Vehicles.
- Designed and sized custom high-pressure counterflow heat exchangers using thermal analysis, heat-duty calculations, and NIST REFPROP real-fluid property data. Designed custom manifolds, high-pressure fittings, tubing, welded joints, sealing interfaces, and seal glands.
- Implemented 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, safety-critical relief devices, and other high-pressure components based on required flow capacity, pressure and temperature limits, set points, and failure modes.
- Led client-facing projects from kickoff and concept development through delivery of IFC engineering packages, commissioning, and closeout. Translated operating needs into requirements, coordinated multidisciplinary teams, and managed client reviews and approvals throughout.
