" Realty is a fast-growing real estate business located in Tampa, Florida. We first began working with Alex and his company Data Subsystems Inc, in 2008 and continue to work with them today. Alex is our "to go guy" for any IT solutions. He has helped us with multiple projects: client database, developed a fully customized web solution integrated with MLS and includes a detailed deep search feature which is updated daily. Moreover, Alex has created SEO optimized listings for our immediate real estate market and the surrounding communities which continues to generate a number of quality daily leads. Additionally, he hosts and manages our servers. I just hope Alex will outlive me, since I do not know what I would do without him :)"
