John has provided expert knowledge and advice on multiple occasions that have helped me better serve my clients. John is a Rockstar!
Not only is John a very talented programmer and developer, he is also an excellent communicator. He has a talent for taking complex subjects and communicating them in terms that anyone can understand. This is a rare combination. This ability has enabled me to take my skills and knowledge to the next level. Thank you John for for all that you do.
John is top-notch and a great guy to work with.
John is a fantastic and patient tutor, who is not just able to share knowledge and communicate it very effectively – but able to support one in applying it. However, I believe that John has a very rare ability to go further than just imparting knowledge and showing one how to apply it. He is able to innately provoke one’s curiosity when explaining and demonstrating concepts, to the extent that one can explore and unravel their own learning journey. Thanks very much John!
John has a particular knack for the development and training of others.
John has a habit of over-delivering on the expectations he sets up. That’s why he’s the best.
John did an outstanding job on my project. I highly recommend him and look forward to working with him on future projects.
John is an excellent teacher.
John and I have worked together on numerous projects. John is very quick and efficient and was a pleasure to work with.
I recommend John every chance I get. If every person I worked with were as committed to excellence, punctuality, value, and unquestionable integrity… the world would be a better place. Highest recommendation.
John really delivers!
