Roles security in applications

I have MS in Information Security with research interest of Cryptography. I have implemented Cryptography algorithms in Java and C, written security solutions in J2EE and Java, have implemented datastructures in Java, and built two websites for research / proof-of-concept purposes. Additionally, ~2 years of IT experience. I have taken Graduate level courses in Cryptography and Security that dealt with analysis of Cryptographic protocols, my Masters level project involved design of a Cryptographic protocol for a specific authentication problem in three-party settings. Notable projects completed include implementation of cryptography Algorithms for Standard Transfer Specification(STS), Design and Implementation of Android App and Backend for Medical Records Storage Service (this service stored all data encrypted in Databases), development for application for signing XML documents using XaDES standard.
