Hi I have 10+ years of telecom application development experience ( telecom billing product -call control (ISUP/INAP/CAMEL call handling), short message routing application, telecom tools development). I am very strong in C++/Unix , core java and advanced oops design. Recently I have undergone a training in 3G mobile protocol developement. I have very good knowledge about WCDMA, its various layers and gone through 3GPP technical specs. Now I am looking for 3G mobile development opportunities.
