Awesome mentor!
Pretty good
Could've been better
Needs improvement

I was having a complex challenge in my Python web app, that got me stuck for 2 days. I initiated a session with Martijn then. He found where and why things did not work, fixed the code, and help me understand it, all within 30 minutes. Very knowledgable and fast. Will use again.

The mentoring was great but the call was terrible. I'm using Debian (GNU-Linux)

Great Session! Has helped my answer all my questions and more. Looking forward to next time!

Martijn's tenacity to help superseded fiscal contexts in his outreach to assist a question posted on a free-forum. Often these open forums exhibit answers or responses minimal in their conclusive assistance, yet in this circumstance Martijn persisted in providing options, ideas, and outside resources to find a solution. To notch mentoring!

Excellent session, very clear and knowledgeable. He helped me solve a particularly hard problem with regular expressions I had, and I also learned and understood how it worked in the process

I learned more in an hour than I could studying weeks on my own. Martijn is brilliant and patient.

From the stance of a novice program hungry for knowledge, I can easily say I left this short mentor session satisfied. It seemed as though this mentor was able to quickly to asses my level of skill and appropriate his descriptions and guidance to best convey solutions to what was sought. Through which, much progress was made in only a short amount of time with respect to actual repairing of coding, and as well broadening my understanding of concepts associated with the Python language. I highly recommend this mentor for Python programming assistance. Hats off to Martijn Pieters! Cheers, J.M.K.
