Igor is very good teacher. He helped me with learning and understanding of MySQL and Im grateful for his support. From the outset, Igor demonstrated a profound knowledge of MySQL, and his ability to convey complex concepts in a clear and accessible manner greatly facilitated my learning process. In conclusion, Igor's proficiency, teaching style, and dedication have made a great impression on me.

He is a nice guy ans have a good experience and knowledge of programming. With patience, he managed every single questions in an understandable way and gave some examples to make the new knowledge become much more easier. Moreover, it is very nice that he did share his valuable experience about how to program readably and often gave some advices on how to improve the coding skills. In my opinion, having a talk with him about the coding skills and listening to his explanations were somehow a good opportunity for the beginners to find the interest in programming.
