“I had the pleasure of working with David Sosenko and Expert Data Systems in the fall of 2009 in designing a new Web site. David helped move me through the process from A to Z, offering invaluable insight and advice at an affordable price. Whenever I asked him for an adjustment or a change, he was open with me about what it would cost in time or money and was always able to accommodate my request or offer a work-around that kept me within budget. All work was done professionally and quickly, and my organization was able to launch our new and beautifully designed Web site on time and on the money.”

“If I were starting a small business today or expanding one, the first person after my lawyer that I would call would be David Sosenko of Expert Data Systems.
In 2010, web design and development is the foundation of many, if not most businesses and there is no more creative, efficient, thorough and accommodating individual/company in the field of web design and development. I have been working with David and Expert Data Systems for many years, and over time, David has built, developed and refined our web presence, including a very successful retail store. I can’t count the number of times that we reached out to David to address a crisis (not that he created but rather we encountered from customers) where he responded quickly, and resolved the issue swiftly and effectively.
If you need unparalleled customer service, reasonable pricing, and the highest level of competence from a web designer/developer, David and Expert Data should be contacted immediately.
I am happy to answer any questions from inquiring minds.”

“I have had the pleasure of working with David Sosenko twice in my career. First at Citibank, and again at Sovereign Bank. As a colleague, David was a great team player with outstanding technical skills and a “can do” attitude. Being in IT for over 25 years, I literally have thousands of contacts; but when I recently started my own web-based business I reached out to David to help us with design, set up, and e-commerce development. ”
