It was great working with Vladislav. He certainly knows the software and tools needed to make an ecommerce site. His feedback and contribution was great - added enormous value to the project. I will be using him in future projects as he is so easy to work with and 'gets it' very quickly. He was very quick in his turn around times. This development was a great experience and makes me look good!
