I had a very difficult time working with Olek. He was always concerned about the payment prior to proving his worth. Rather than doing things right, he would constantly demand payment first, which got frustrating. I found myself paying him way more money than anticipated to fix the same reoccurring issues everyday. I felt taken advantage, which led me to leave this review. There was also a language barrier, making communication difficult. Unless you speak Russian, save yourself the headache.

Olek was very responsive and dedicated towards the project. He is an advance developer with a passion for problem solving. There was a little bit of a language barrier, but once we understood each other, We had no issues. I will hire again.
