Hello!

I'm Oleh, but online, I usually go as OlegWock. I'm a web developer, primarily working on the frontend side of things. I really enjoy building something pretty and useful, and the frontend enables me to do both at the same time. In the past, I also worked a lot on browser extensions.

Besides programming, I'm interested in cooking, cycling, and the graphic design of printed media. I speak Ukrainian, English and a bit of Slovak and would love to chat if you have something to say.

Here I write about React, animations, and occasionally about browser extensions.
