Senior Software Developer

• Development of C/C++ for transaction processing and network communication (SSL, TCP/IP) with various payment processors.
• Ported transaction processing application from Visual C++ 6.0 to Visual Studio 2013 C++ compiler. This application was originally written in C, and was recompiled so C++ could be utilized to the full extent. Extensive updating so that the C/C++ was up to ISO C/C++ standards.
• Updated and certified the processing software for credit card and debit card transactions to TSYS (major credit card processor). Extensive communication and coordination with various technical analysts over email and phone.
