Community Service
Code Club
I am a mentor at CodeClub, an international non-profit organization that helps teenagers from 160+ countries worldwide learn to code.
I started working at the Ukrainian branch of the organization two years ago, and became the youngest mentor there.
Since then, I've taught 40+ young people from different parts of the country. Not only did they acquire a solid knowledge of the basics of coding, but, what's more important, they got interested in programming, and many of them decided to link their future lives with it.
I mentored different students. Some have written their first line of code with me, while others had prior programming experience and were looking for opportunities to boost their skills.
I conduct weekly online lessons via Zoom, which last about 2 hours on average.
To improve students' learning experience, I built an online LMS (learning management system). Now students have everything in one place, just one click away from them: from sending the homework and receiving the feedback to real-time chats with the mentor. Check it out!
