Summary
19 years old, living in St. Petersburg.
I am currently actively studying frontend development. I am also studying according to the plan presented on the website of The Odin Project, at RS School in the frontend direction and taking an intensive course in JS from T-Bank. I participate in hackathons and develop my own projects. I attend thematic meetups.
I learn quickly
I love learning new information and always complete any task, no matter how complex.
My goal is to become a sought-after developer
