Again, Rick is incredibly fast, fundamentally understands how servers and Django functions and is pleasant to work with. He's been incredibly helpful and makes great recommendations.

This mentor really helped me overcome problems with Python. He also helped me improve my skills by explaining exactly what he was executing. A great mentor all round.

Rick van Hatten is confident, knowledgeable, patient, and an excellent mentor. I am a beginner, but worse, the kind of person who asks many questions. Rick was able to answer all my questions, clearly and concisely. When I need help, I will be hoping he's available.

Rick provided me the consultation and actionable direction I needed.

Experience shows clearly when you can identify problems quickly. You can tell when someone thinks clearly. Does not matter what the problem is.
Asle Benoni Jun 24, 2015

Did a great job, quickly wrote the query and optimized it.
Jeffrey James Jun 23, 2015

Clearly knows his stuff but we seem to have run into a Python bug combined with a badly configured server so not much luck resolving the problem.
Sebastian Jun 23, 2015

Rick was great, helped me fix my issue quickly and was super responsive
Bryan Pellegrino Jun 15, 2015
