  3. 3. Professional Experience FirstData Commercial Services - Hunt Valley, Maryland Oct 2014 – Till Date FirstData Commercial Services-Syntel Ltd, India Aug 2010 to Oct 2014 First Data is a provider of electronic commerce and payment solutions. The company's portfolio includes merchant transaction processing services; credit, debit, private-label, gift, payroll and other prepaid card offerings; fraud protection and authentication solutions, credit reporting agency services (through First Data Merchant Services Corporation); electronic check acceptance services through TeleCheck; as well as Internet commerce and mobile payment solutions. Merchant Front End (MFE) is an application having multiple processes which receives credit/debit/gift card transaction from the different merchants in variety of message format. MFE contains the complex business logic to process incoming transaction & perform parsing, formatting & enrichment of transactions & route the transaction to intended association for approval. The approved transactions are then submitted through firstdata for settlement in order to fund the merchant. First Data's Merchant Front End systems process authorization and settlement transactions for credit and debit cards. This runs on AIX/Power 6 OS/hardware configuration. Merchants provide authorization and settlement transactions through a combination of leased line, IP connections and Dial carriers. The Merchant Front End development language is C/C++ and XML. Currently this application is being maintained for the existing customers and also enhanced to accommodate newer merchants. Projects & Assignments PRODUCT IMPROVEMENT - MERCHANT FRONT END Designation: Team Lead Duration: Aug 2010 – Till Date Responsibilities:  Design and development of payment solutions for communication protocols, user interfaces, transaction processing, receipts and reports in order to store and process data with interface First Data authorization systems.  Co-ordination with the Authorization system architects and Third Party Merchants to ensure application integrity of the newly developed/enhanced payment solution which involves ensuring proper data encryption procedures, the mode of transmission, frequency of transmission, type of transaction.
  4. 4.  To perform data analysis, debugging and to provide resolutions to avoid financial impact to merchant and customer on occurrence of issues in POS application related to transaction requests, adjustments data, settlement and clearing data.  Involved in Certification Testing of Commercial cards & Prepaid cards, EMV technology and the Chip & Pin process.  Implementation of EMV certified devices to new generation ePOS registers; EMV changes to ePOS and related PinPads for meeting standard EMV requirements.  Analysis for MasterCard Terminal Integration Process and ADVT Visa for various regions like Latin America, Canada, Mexico and Caribbean Islands so as to customize the requirements as per the local mandates.  Spring and Fall Release enhancements for Visa, MasterCard, Discover, Amex, Diners etc for different authorization and Settlement formats.  Involved with Developers and Business Analysts to define and create Test plans, Test coverage matrices, Test Strategies and corresponding Test cases.  Designed and coordinated creation of Manual/Automated Test cases according to requirement and executed them to verify the functionality of the application.  Automation/Manually testing the various navigation steps and basic functionality of the application.  Primary involvement in creation of data flow diagrams of the application for test scenarios.  Designed and developed UNIX shell scripts to automate the testing for Change Release projects.  Extensively worked in UNIX to perform different file operations such as searching and data comparisons through Vi Editor and various commands like grep, cat, ls, find, tar, sed, awk etc.  Performed the FrontEnd validation using SQL Queries and also validated the UI values against the database. Used various DML and DDL commands like Select, Insert, Update, Sub Queries, Inner Joins, Outer Joins, Union etc. for the data retrieval and manipulation.  Used the Bugzilla, Clear-quest and Equip as defect tracking system, including
  5. 5. submitting and assigning defects to the application developers along with the release of defect aging reports. Technologies: C, Shell-Script, AIX, Parse/Format Handlers, XML. Team Size: 5 Major Projects EMV with Common AID. With EMV being the future of payment and making the line between debit and credit thin with Durbin amendment. Merchant will have the facility to route the transaction to a least cost route if the EMV chip supports common AID. The transaction will be sent to DRD system to obtain a preferable route for the transaction. I had to prepare and test transactions for MC/Visa credit and Debit BINs. Debit with Pinned and Pin less transactions Project objective is to enable merchant to send PIN data for different debit networks like MasterCard, Visa/Interlink, FiServ and Pulse. The testing efforts for this project include Key Exchange messages, PIN Encryption verification through HSM, Association certification and Terminal software certification. POS PINless project. Objective of the project is to let merchant process Signature Debit transaction below floor limit through debit network. This saves merchant processing fee/taxes and also gets funds faster to merchant. Merchant credit transactions, if following POS PINless guidelines, are transaction processed as debit and appropriate response is sent back to merchant. E2E testing was done to verify all reporting and reconciliation to merchant is accurate. DRD(dynamic routing decision), Durbin Amendment testing for transaction to avail Least Cost Route to merchant transactions. The objective of this project is enable merchant to select least cost route path dynamically from the available list of supported network. With the cutting edge competition different debit networks apply different fee for transactions based on Asset Class of card and Transaction amount. With DRD system merchant can selected different network to route his transactions and avail best transaction fee. Testing efforts include test data setup on DRD system, troubleshooting DRD application, regression, functional, certification and UAT testing with various debit networks. Wallet applications and Apple i-pay, Association tokenization solution. Fraud prevention has been FirstData premiere focus for merchants. FirstData is the first
  6. 6. acquirer to launch the Apple-pay payment method. We have made changes to receive tokenized transactions from merchant applications and send them along to respective association and get processed. Customer can tokenize a Debit/Credit card via wallet/Apple pay application on their smartphones and then use the application to make a purchase either in Retail or CNP environment. My role was to make sure the functionality is working as expected. Testing efforts involved integration, regression and certification testing for Switch changes. TransArmor (FirstData Fraud Solution – Tokenization) and Offers (FirstData loyalty program). TransArmor is FirstData proprietary product for merchant who wish to protect their data against fraud. The tokenization application is downloaded on the Terminal and has to be certified with FirstData to use it. Merchant using the TransArmor application can Tokenize and/or Encrypt the data details during Auth process and then send the same details during settlement. FirstData back office does a decryption to get the real PAN and perform settlement. So the real PAN never flows on the network. Feature works with any type of transactions and supports other features as well like, POS Pinless, EMV, Offers. Testing efforts include TransArmor and TransArmor with CA feature testing, merchant setup, test card encryption and decryption and understanding RSA and VSP tokenization flow. Fall and Spring release for Association/Networks. The testing efforts include regression, functional and certification testing for different association for association related changes during release period. Understanding of association format is must in order to troubleshoot and certify a specific requirement. Each project testing includes offshore & on-site work assignment and review. During the complete tenure I am the primary resource to Maintain, Support and Update Debit regression region and I am responsible for the correctness, accuracy and relevance of test cases and test database. Platform/Tools Used : Unix (AIX) C Programming, DBX, Net-X library, Xerces Library for XML Parsing, parse-format handler, Association and Merchant Specifications. Awards & Recognition:  Syntel Value - Stretch and Synergy Award  Syntel FDCS Monthly Star Award  Received individual appreciation for Network certification testing and Bravo award for the same from FirstData.
