What's the difference
Overview

I solve problems. You can hire 2 developers for the same price, but once you run into an issue none of them can solve, you'll probably understand why 'cheaper' isn't 'better'. And no, I don't write code twice as fast as the others do. I work better, not faster.

“We needed some very complicated web development. I was amazed how quickly Oleg understood our very obscure requirements. Although he was very responsive, I failed to find time to check in with him regularly during his development. That is why I was amazed when he delivered the product. He had the insight and intuition to fill in all of the subtle details that I failed to give him originally. He did everything the way that it should be done, with code that was clean, efficient, and fully functional. I have no doubt I will hire Oleg again in the future.”
