Senior C++, BASE24-eps Developer

Responsibilities:

  • Involved in analyzing the ISO message structure for “log on”, “key exchange”, “pos purchase” transactions, in existing BASE24-classic system.
  • Created the technical high-level design document having big picture of modules participating in BIC ISO transactions.
  • Involved in designing parent/derived classes. New derived classes have been registered with Component Factory (to obtain an instance of the interface) and Message Delivery Component (to receive external messages).
  • Created the technical low-level design document having C++ class hierarchy and CSM’s to be developed for parsing and building certain fields of ISO8583 message, by inheriting corresponding module using polymorphism.
  • Using Visual Inspect C++ debugger, debugged the vanilla C++ BIC ISO code by building IS (Integrated server) using respective “non-optimized” C++ modules.
  • Configured the “BIC ISO interface” in ACI desktop UI.
  • Resolved the issues in “800 NMM” message for logon. Did C++ code changes in parsing method of field 48.
  • Resolved the issues in Vanilla C++ code, for handling the inbound and outbound “key counter” logic for “key exchange” transaction, by inheriting corresponding module using polymorphism.

Previously it was “Account 1 Ledger Balance”.
  • Involved in fixing issue “This Usage never expires". After doing successful Internet Prepaid timeout transaction (stand-in authorization), card usage record was created without "next begin date and time". Instead of date-time, it was showing "This Usage never expires". This transaction uses stand-in prepaid authorization scrip. To fix this issue, I have done code changes in that script and Balance Read subscript.
