Sizing and designing refrigeration based technologies for exploratory Heat Pump markets. Decarbonizing markets that currently require fossil fuels for heating and cooling industrial processes.

Cognizant Engineer for most of the Helium Recovery Suite of products from design to Customer Service. Including all Helium Liquefiers, Purifiers, High Pressure Recovery Systems. Consultant for complete liquid helium systems from drafting to installation specializing in Material Physics research laboratories, MRIs and MEGs. I am very excited to help improve and configure some of the best products in the world, for the most prestigious Physicists, especially in the emerging field of Spin-tronics.

Testing and engineer cryogenic equipment. Specifically I work with Liquid Helium production and all ancillary products such as purification and distribution. After taking over the plant engineering I have taken a helium loss rate of 800$/day down to only 200$/day. Saving over $200k annually.
