Colleagues describe him as "John is definitely the man to go to, if you need to solve complex coding problems. He has the ability to see things from the client's perspective, which resulted in practical and robust solutions for our clients. I would recommend John for anyone looking for a highly skilled web developer (and photographer!)", "John's one of those rare creatures—a diligent developer that puts his head down and gets on with the job with a minimum of fuss to deliver a great piece of work. What makes this special is that John leaps the hurdles along the way without so much as breaking his stride. While working for us those hurdles were of a magnitude that daunted lesser developers, but even tasks such as learning a new programming language, or worse—working with scrappy legacy code—never held John back. Some developers significantly add to a manager's workload, John on the other hand just seems to magically make the problems disappear. It's not magic though, it's a good old fashioned mix of raw talent and solid work ethic. Hire John. You won't regret it.", and "John was an excellent web developer whilst at Alienation Digital, capable of solving complex problems quickly and without fuss. I would highly recommend John to anyone looking for a loyal and efficient web developer."
