About me

I am an experienced developer having a wide range of expertise in various IT fields.

I had held Top-Rated status on Upwork for more than five years.

And now I decided to try my powers on the Useme marketplace.

My principles are to provide a workable solution with a thoughtful design, even if it takes a little more time. Also I provide technical justification if your requirements cannot be implemented.

My geographical location is the Western Siberia.

I was in Poland as a tourist. I studied Polish and know it a little.
