"JR Simma is one of the best software engineers I have ever worked with. He is a member of the rare breed of software engineers who can not only write good, efficient, bugless code, but also understands the hardware enough that he can debug both HW and SW problems."
-- Ray Suda Hegemon Electronics

"JR Simma is one of the finest software engineers I've worked with. He quickly comprehends new technologies and is likely to improve upon them in the process." *

"I have worked directly with JR for more than 2 years designing and developing embedded software and systems. I have found him to be hard working, honest, and thorough. He communicates well, works in both a team environment and as an individual, and pays attention to detail. JR is also a top notch programmer, who maintains an excellent system perspective throughout code development. In addition, his extensive experience in data link communications has been valuable many times, quickly identifying issues that would take others much longer to find. I highly recommend him for any embedded systems project." *

"JR Simma is by far the best programmer I've ever met. I work in a large scale company providing software support. I've supported software on numerous enterprise applications and have examined software written by hundreds of designers. I've debugged problems down to the bit level many times. On a few occasions I've been completely stumped. I've called JR Simma on the phone and described the problem symptoms and what I know about the problem. Literally over the phone without seeing any code, he has pin pointed the problem. That is amazing. No other software programmer I know comes close to him in depth of knowledge." *

"Every time I see a semi trailer stop safely, I thank Simma Software." *
