    “From the get go Dimitris was on board and displayed a great depth of skill and knowledge in the areas required for the project. He was up front that the specific application of the requirements for the website configuration were in a way he hadn't applied before but was confident in his approach which was validated through the delivery. Dimitris was helpful along the entire task, worked around our time zone differences and took the initiative to follow up on changes that weren't reflected immediately when we were offline. It was a pleasure to work with Dimitris and I look forward to working with him again.”
