This was my firs session with Nejc and I cannot express how grateful I am for having the opportunity to pair program with him. He was really patient, non-judgmental and was willing to go beyond the mile to help me get unblocked and understand the problem I had to solve + I learnt skills for debugging code as well! You can tell he is very fond of mentoring people and many junior developers like me appreciate that. I am looking forward to keep working with him in the future :)
