Client: Confidential, Hunt Valley, MD, USA
Title: Senior Project Lead/ Lead Designer and Developer

Project: Cardnet Nashvilleswitching systems for online transactions processing

Confidential, is a global leader as acquirer serving millions of merchant establishments and thousands of card issuers. As an acquirer processing credit/debit/loyalty cards, checks, the underlying applications are broadly classified into Front End switches (Authorizations) and back-end Mainframe systems (Settlements). The front-end applications are C/C++ written on UNIX-AIX on IBM's RISC 6000 64 bit machines with processing nearly to 3000 TPS (transactions per seconds). Perl and korn shell scripting jobs are run at front end for carrying out file processing and other file moving activities for files received from back-end Mainframe systems.Sockets are used to connect between merchants using phone lines and associations. Multiprocessing applications run on different processors thus increasing the collective throughput. Load balancing happens with multithreading with additional layer between merchants and switches for phone lines. Mainframe systems are connected to AIX servers by coupling of CICS sockets on their side with Unix Sockets on front end sides.

Responsibilities:

• Developing C++ and XML interfaces merchant configurations for phone lines symbols
• Developed C++ programs for loading XML configurations into shared memory
• Coded new applications in C for transactions activity alarming and event handling.
• Carrying out redundant code analysis and removing it to increase overall throughput.
• Creating new korn and Perl scripts for carrying out certain scheduled tasks of merchant and terminal extract file building received from Mainframe systems.
• Conversion of 32 bit file processing application to 64 bit file processing application for larger file support of merchant bases.
• Creating utilities in korn scripts on timely manner to almost automate entire production search methodologies.
• Successfully porting fall and spring releases for VISA and MasterCard associations twice every year.
• Performing extensive code reviews and provided optimization suggestions wherever required.
• Maintaining project schedules, work breakdown structures and maintaining issues and discussion logs
• Creating timely project status reports, charts and graphs for presentation purposes
• Attending meetings with Engagement Managers and PM's for deciding new strategies for team expansion onsite and offshore.
• Planned and coordinated administrative support activities to ensure goals and objectives are accomplished within time
• Carrying out risk analysis and identifying risks in projects

Environment: C, C++, STL, AIX, XML, Korn scripting, TCP/IP, sockets, multithreading

Title: Tech / Project Lead
Project: Amex Punch Cards

Confidential, has a set of proprietary cryptographic device drivers for Amex punch cards. The application had to load/ unload device driver's kernel modules at startup using startup scripts in bash shell on Linux. The application also had other programs which help in the overall process of creating the end message to be printed on the mag. stripe of the cards.

Responsibilities:

• Attending meeting for requirement analysis with onsite team members and clients
• Bug fixing and maintaining C, C++ programs for fine tuning applications
• Creating/ modifying the interface of startup loading/unloading of device driver kernel modules.
• Helping to port certain scripts at the test environments with other team members maintaining concurrency and integrity of system.
• Bug fixing and integrated systems testing on the TE's (test environments RHEL)
