Doszhan Kalibek
Full-Stack Developer

DevOption is a one-person studio. If you want to talk directly with the person who will actually work on your project — you've come to the right place!

My name is Doszhan. I've been passionate about programming since childhood. Over more than 15 years in this field, I've gained extensive experience working on different projects and with different teams.

Working with me, you:

you minimize the "telephone game" effect, where information loses its original meaning as it passes from person to person;
you know exactly who is actually working on your task;
you work with a developer who has experience on projects in Kazakhstan, the US, and Europe. Early in my career I worked at various web studios, then moved to a major bank. I built up a broad range of experience across very different working environments.
