Extremely happy! He solved the primary issue and explained it to me in a way I could understand. This was a persistent problem that several other developers failed to fix over the past year.

My second order and it was just as good as the first. I can check the results instantly and have seen a dramatic improvement thanks to the changes he made on my Linode server. Every completed job included a detailed breakdown sheet explaining the problem, what he did to fix it, and potential future steps. Very professional and detailed work!
