What Clients Say

“Christian is an exceptionally professional freelance engineer my company has the pleasure of working with for almost a year on several projects. He is engaging and solution driven, and often found clever solutions to any problem encountered during project development. His skills cover a large breadth of design aspects, and his experience with a variety of nuanced topics frequently provided insight into design aspects not previously considered. He is expedient, reliable, highly communicative, and capable. Easily the best freelance engineer we've worked with.”

“Christian did an excllent job on this project. He is organized and thoughtful in his approach. We highly recommend him.” customer
“Christian's work is outstanding. The level of detail and expertise was well beyond our expectations. When problems came up (as they always do) he was quick to explain what was going on and how it was going to be fixed. He worked diligently and quickly to make sure we were up and running and he always made certain that we understood every part of the implementation. We could not be happier with the results.”
“I feel that the company is very reliable, knowledgeable, the quality of work is excellent. They are always on time. I would recommend them to everyone.”

“We were lucky enough to be introduced to EE Proto after a large project fell stagnant with another company. Christian was able to put our project back on track with answers to the problems in the first 30 minutes we spoke. After sharing ideas and our goals the project is nearing completion in record time.

I would suggest speaking with Christian / EE Proto, LLC before making any decisions with another company. You won’t be disappointed.”

“I am a 30-year aerospace engineer and now business owner and have worked with many professional engineers of all disciplines over the years.

Christian with EE Proto was recommended to us by a local business. We issued Christian the project specifications and timeline and Christian produced exactly what we wanted. His MCU coding and PCB development work is excellent.

I highly recommend EE Proto engineering services.”
