building SMS services for mobiles

Software Engineer SMS Java MySql ...
Software Engineer
  • I worked on building SMS services for mobiles, like Weather, News, Competitions and many more (about 20+ Services). The key factor was to connect with Mobile providers to send and receive SMS, and then build services on top of that. 
  • The services shared many features, like subscribers, content, and scheduling of sending, hence I developed a single code base that can manage most of the common services and it was possible to add a new service dynamically without changing code.
