    I am sorry because I do not have the time right now to leave the kind of recommendation and my full feelings for the work that Ms. Rajput has been doing for me and my company! Simply said there are just not the words to express how I feel about the service I am gotten and am getting from this man. All the best!!!

    Mr. Abdul Rehman has to be the best open source IT developer with any PBX or Predictive dailer. No one else can even understand what needs to be done to create the amazing capability for connecting customers of any kind! Nothing is impossible with this man! We will be using him for a customized use of Google's Speech to Text programs to translate incoming calls and voice mails and our staff's intake information directly into our data bases. This is just one example of some of the expertise that this Developer has in his vast experience and way of thinking outside the box to get everything we needed to compete and automate done on time and eliminate some of our time consuming tasks and save time and money. You will not be disappointed with this man! Eddie McKibbin President and CEO Optimum Healthcare
