Colleagues describe him as "I am writing this recommendation months after leaving Tapjoy only because I continue to apply all the valuable lessons he has taught me during my 2 years there, and I need to give the man some credit. John was the Director of Engineering at the time, but he took it upon himself to always make time for each one of us at the Boston office to listen, give advice, and/or talk about random nonsense. His advice on communication skills and engineering principles will remain a priceless memory of my Tapjoy days, and I couldn’t be more grateful. Thank you John.", "JR is one of the most competent folks I have ever worked with. He's an outstanding, level-headed leader with a great deal of technical acumen who doesn't get rocked by the trials and tribulations of working in a fast paced environment. Any team is lucky to have him!", and "John is the nicest and most brilliant software architect I have ever had to work for. I have been very fortunate to have him as a mentor. He has a breadth of knowledge and technical depth that is almost unequaled. He is an inspiring technical leader and a great human being."
