ARCHITECT /team lead
Senior Full Stack Engineer
One of the first things you should know about me is that I’m a computer geek to my fingertips. My programming experience started with learning Visual Basic back when I was a child. Since then, I’ve tried almost every technology in Web Development and DevOps to create neat solutions for the applications I've developed. I’m always interested in mastering new and challenging technologies.

I enjoy finding Open Source projects to contribute to. A few years ago, I realized that working with a certain technology stack is not enough - it’s very important to share your knowledge with others. So I’ve established the Ruby Boost practical school to teach former students and everyone who wants to start an IT career in future.

In my spare time, I like riding my pit bike across the plains and mountains of my country.
