Hi! My name is Polina, I’m from Saint Petersburg. I currently work as a QA Automation specialist and am interested in blockchain technologies. I found out about the course through related online communities.

The material, delivery, and organization were all top-notch. Congratulations to all my classmates on completing it, and I wish everyone the best of luck in their work!

Hi! My name is Kirill, and I live in Moscow.
Currently, I work as a teacher at a programming school, teaching C++ and Python to high school students. About a year ago, I started studying blockchain technology and everything related to it, and I began writing a blockchain course for school students.

The course is now complete, and I teach it successfully, while my interest in blockchain technology continues to grow. I’m eager to dive into real blockchain development! Very happy to be here among like-minded people.
