ABOUT ME
Author of Mastering Python (https://www.packtpub.com/application-development/mastering-python), a book to teach advanced Python programmers everything they need to master the language. No cure, no pay for specific problems. I only accept issues if I'm confident I can fix them in a short amount of time. Always happy to give advice :) Over the last 15 years I've started several companies and according to Stackoverflow I've helped ~3.2 million people using my knowledge. I'm one of the top Python contributors on Stackoverflow and have over 30k points. My main interests are scaling of large infrastructures and websites to millions of users as I did with my last large startup (fashiolista.com). I have many years of experience consulting people and companies with varying programming, dba and sysadmin problems. My profile only shows my main expertise but I have experience with a vast array of technologies so please don't hesitate to ask for advice on any matter. Generally I am available from 10:00 to 0:00 Amsterdam time (GMT+2).

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.
Francesca Jul 10, 2015

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.
Jarad Jul 05, 2015

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
