Josh Cook
Product Manager (TotalTV) at Rovi

I worked with Joshua on the TotalTV project where he was the lead engineer. He was responsible for the backend services, code reviews, system architecture, devops, and many other critical functions. The project would not have moved as blazing fast without his quick thinking, impressive coding, and leadership. His breadth of knowledge and ability to quickly learn new things are critical qualities for anyone in a lead position.

Josh is an extremely capable individual who's personal drive and motivation to provide simple, well thought out solutions and systems for complex and integral projects have been a key factor to the continuing and future success of the Ultraspeed Group. It's rare to see such attention to detail and pride in one's work in someone of his age. I'm positively refreshed by his attitude to take an active interest in other areas of the business in implementing his development projects.

Josh is a first-rate developer. He has a passion for doing it the right way, combined with a blazing output rate. He also does a very good job and keeping track of the latest trends and projects that improve the performance, maintainability and scalability of web applications.

Josh is a creative and motivated team leader. [His] accomplishments and professional presence is comparative to someone who has been in the work force for 20 years. He continually finds ways to implement new concepts and existing concepts in a more efficient fashion. Always dedicated to the projects at hand and making the best decisions to assist his coworkers and the companies needs. I fully recommend adding Josh to any team that requires growth, he will drive the project to fruition.
