To whom it may concern:

Vincent White was employed as Mechanical Designer at FlexGen® Power systems and known to me since 2014. During that time, Vincent was responsible for all the solid modelling work involving the packaging of our technology. Vincent has been a very dependable person with solid ownership. I have worked with several designers over my career and I would say that Vincent’s proficiency in modelling and use of the various features in Solid works is advanced.

I am happy to be a reference for Vincent and wish him well for his new job pursuits. Please feel free to contact me if you have any questions concerning Vincent.

Sincerely

Gopi Balakrishnan Vice President, Operations & Customer Engineering Direct (281) 928 1212 gbalakrishnan@flexgen.com
