Hi, I hold Masters degree in computer science and have around 20 years of IT industry experience of developing small to enterprise level application that includes dashboards, messaging/communication applications (SMS, Voice, and Email), online stores, catalogs and many other data-intensive applications for clients like AT&T, US Army, EPA, NIEHS, DMV, Florida Power and Lights and others. I have solid experience in architecting and developing messaging applications using providers list CLX/Mblox, Twilio and others. In past, I have developed SMS self-service applications for a couple of my clients too. Your target application is not different. I am confident that If selected, I'll be able to deliver a quality product within the agreed time-frame. If you have any question, feel free to contact. Thanks, Atif
