Senior Elixir Developer

I am top rated Elixir/Ruby/Vue developer with over 10k hours logged at Upwork. Working as part of a team or independently, I enjoy building anything from quick prototypes to large, sustainable systems. I have a strong interest in thinking about a product, understanding the problem it is trying to solve, and using right tools to solve it.

"Sergey was instrumental for our team. We are a small team of rails developers and honestly didn't have time or expertise to properly setup production servers. This is where Sergey hopped in on multiple occasions to help us set up the server and improve the setup a couple times as we grew. I would definitely recommend Sergey!"
