Recommendations

It is my pleasure to provide a strong letter of recommendation for Josh. I have known and employed Josh for 12 years. He has been a consummate programmer, both for the UI design elements, as well as the implementation side. In addition, his support of customers has been outstanding. Indeed, his contributions resulted in a scientific publication that detailed the program he helped develop. I hired Josh to write two different applications, SPICE and Pestle. Josh’s expertise in UI/UX was highly evident throughout this process. He developed a modern Mac UI that users could quickly grasp and work with. Particularly with SPICE, for which the analyses can be very sophisticated, this became paramount. Josh is an outstanding programmer, who excels in UI/UX design and implementation. He is certainly very clever, inquisitive, and is an excellent resource. He is someone who interacts extremely well with users and engineers alike, and I am sure he will enable any programming effort synergistically.

Dr. Mario Roederer, 2019

Josh is one of the best developers I have ever worked with. He is truly interested in software development and is keen on expanding his skill set in Objective C and Xcode. He is fast in understanding complicated system and is able to contribute unique ideas in system design and implementation. Besides technology, he is also interested in identifying and utilizing best practices in software development. Josh also likes to work with other developers and share his knowledge with others. He has strong communication skills and a good sense of humor.

Dr. Yongjian Guo, 2010

I hired Josh as a software developer for a very challenging scientific project. Josh was able to acquire the complex subject matter knowledge in a very short time and used his critical thinking and outstanding technical skills to deliver a very high quality product. Josh works well with his peers, is always ready to lend a helping hand and contribute his knowledge, and has forged very solid relationships with our scientific community.
