I can teach you Python & more. Systemically. Pragmatically

I'm lucky that I had a chance to be Ivan's ward. He's a fantastic mentor who always makes you think harder, looks deeper into the root of the problem, and never forgets about your code's performance, readability, and complexity. When you resolve your task you need to be ready to answer these questions "What is computational complexity of your solution? Can we make it better?".  I learned a lot from Ivan: how to find documentation and ask right questions, different data types, algorithms, TDD, better naming and many other things. His incredible work inspired me to work on my own mentor skills.

Ivan is an exceptional professional coder ready to share his knowledge enthusiastically! I was pleasantly surprised that he could explain a problem in an accessible way and propose related materials for further study. And all of this in a friendly and welcoming manner.

Ivan and I held several pairing sessions discussing some algorithms. In particular, the session on Prefix Tree helped me a lot due to the apposite format – walking through the problem via hint questions instead of just providing a ready-to-use explanation. Thanks to this, the topic was easily understood and remembered) Also I liked in this format that the lesson topic always adjusts to an individual request.

Perhaps, I was the first student of this guy about 10 years ago.  I was hoping "to enter the IT-sphere".  And again, I want to say Thank you, I didn't even imagine how far this would take me through the life.

Ivan will always suggest effective methods for solving non-trivial problems, telling interestingly about complex ones. Explains boring theory with simple examples. He will teach you  the intricacies of python and motivate you to learn even more by your own. Thanks for all the discoveries in the Python World!

I met Ivan at work and he offered me his mentoring with this: "You have a craving for beauty. I can help you to implement it!" And we did it! Thanks to his efforts, I not only write readable and well-structured code, but also fully understand how optimized CPU and memory are, or how much load my program can handle. We also studied Design Patterns and applied some of them in our work projects. Overall I fell in love with Python and programming!

Ivan taught me how to make my life easier and improve the quality of my code.  How solving a large problem is easier in smaller pieces.  Complex algorithms are easier if written in plain words first and then in machine code.  And then rewritten a few more times, because almost always there is a better way.  And not trust anyone, not even yourself. Check EVERYTHING with tests.

Given: a student graduated as an economist, who is working in advertisement business having a strong desire to become a software developer trying Python for a month. What if Dr. Strange speed up the time and looked in which future variant I’d had a chance to get offers from two biggest IT-companies in my country in a year?  I suppose the answer would be 1 to 14 000 000.  And this was the chance where I got Ivan’s contact info and dare to text him.  From this day on my education got much more vivid colours.  I got rid of the feeling that you are maybe doing something wrong or are stuck on something.  Sometimes it feels like Ivan is capable doing everything.  He explains tech while drawing great diagrams and give an advice on next steps in career development, guide how to behave on interviews and how to deal with impostor syndrome 😂 Honestly, I consider Ivan as my lottery prize.

Ivan is a mentor with a capital M, a person with great patience and a holy desire to teach and explain to the student how to do it correctly and beautifully. Nobody else teaches this, not a single article on "Medium" will tell you how really correct and high-quality code should be written with the prospect of long and happy life (of the code). I learned this from Ivan, for which I am very grateful. And I use it with success in my daily work. His lectures are always useful, the practice is interesting and clear, the work on errors makes you take a fresh look at the programming approach in general. Super Teacher! Super Mentor! Thank you very much for your patience and faith in the students! Thank you very much for your patience and faith in students!  #supermentor

I accidentally saw Ivan's post about mentorship and texted him on the same day. I know him from his work at DataRobot – he conducted a 4-days Python workshop. Even then, I saw how his eyes were shining while doing coaching and mentoring, he really gets high when people get the ideas that he is trying to convey. Plus, we had many of aha moments ourselves)) Being engaged individually, everything is an order of magnitude steeper, since Ivan always analyzes and explains the best solutions to problems. Also, you can turn to him with questions at any time – he will always prompt. The lessons with him are not boring, fun and super useful. I definitely recommend it!

In the lessons, Ivan and I worked in two areas: preparation for a technical interview and an application project. In addition to this, Ivan regularly shared interesting materials and promptly answered my questions by text. I had the best impressions, both due to all of the above, and due to the kind atmosphere that reigned in the sessions. I recommend this wonderful mentor to everyone :)

It is a pleasure to talk with Ivan. He is a well-educated, intelligent, cheerful person with a strong charisma,  good humor, and a genuine desire to help others improve. For three months of working with him, I learned several Python "tricks" that I had never used before; I learned a lot about algorithms, data structures, and their efficiency, the importance of naming variables, soft skills, valuable programs for pairing; stopped being stuck in the face of unknown tasks; I believed in myself – that I understand it right and I can do it by my own.

Ivan, thank you for helping me to discover Python. One must have great patience and a sincere desire to help while dealing with newcomers. You have these qualities in abundance. Perhaps someone would say that it is not so difficult to grasp the basics of Python when knowing PHP and JS, but my experience shows that a nudge, advice, and encouragement will not hurt!

I got familiar with Python couple of years ago at one of the trainings organized by Ivan. After introducing the Python world, Ivan organized weekly lessons to continue learning. I liked the relevance of the knowledge gained, their suitability – ultimately the goal was to start using Python for work tasks. In my case, after a couple of months I was offered a place in the development team and this is how my new career path began. On my own behalf, I can only express my gratitude to Ivan for the knowledge and skills transferred!

Ivan is a remarkable mentor and teacher. His technical knowledge, tireless enthusiasm and practical tasks from the world of actual development will allow you to pump your Python skill to level 80 in the shortest time possible.
