Denys Luchko
JavaScript FullStack Developer
Prague,
Summary
I've been programming since I was 7 years old, my first languages were Pascal and PHP, I tried writing in other languages in search of something new but Javascript became one of my favorites. I decided not to include the other languages I learned, because I think my knowledge is not enough to work with them in large projects, unlike JS, where I write code even outside of work for my own needs.
