Environment: C++, STL, HP-UX 11.11, Rational Clear Case, HP-MPI (message passing Interface), CORBA Client: Wind (ITALY) Eps® is the Electronic Payment Systems to provide the payment solutions to mobile operator. Eps behaves as the payment gateway which provides one of the most flexible, open and extensible frameworks available for interchange, gateway, issuer and front end processor requirements. Eps offers telecom operators, businesses and financial institutions a common platform for instant processing of electronic payments. The frameworks provide standard switching features including acquiring, sophisticated routing, authorization, full audit trail and security. Additionally, the frameworks provide rich, safe and simple environment for establishing and managing transaction workflow to meet specific business requirements. Eps can concurrently switch electronic transactions from the thousands of retail outlets to the card payment networks and banks. The most common PoS (point of sales) and network interfaces are built-in and others can be added quickly and effortlessly thanks to its modular payment architecture. Credit cards, debit cards, EFT transactions, prepaid mobile top-ups and electronics gift cards can all be handled using Eps. The Eps incorporates unique software based fault tolerant transaction processing technology which breaks from traditional platform and clustering dependent solutions. The software architechture has been design not only to provide the reliability and availability mandated by payments processors but also to provide a level of scalability and performance significantly in advance of existing solutions.

([login to view URL]) March2004 –March 2005 Project Name: Fraud Management System (RANGER) Environment: C++, STL, Red-Hat Linux 9.0, Solaris 5.1, HP-UX 11.11, Oracle 9.1 (UNIX). Role: Software Engineer. Ranger™ is built around a powerful client-server environment and comprehensively addresses telecom fraud by employing integrated tools that support detection analysis and management. Ranger™ has been developed with a modular architecture where various modules can be plugged in to address the new technologies in the domain of telecommunication. The Ranger™ design accepts different data sources for efficient fraud detection in telecom networks. This aspect of Ranger™ enables it to address fraud detection in the emerging areas like GPRS, IP and other 3G technologies. Ranger™ has a data acquisition layer, which gathers relevant data from various sources such as switches, mediation devices, GGSN, routers, subscriber database, prepaid platform etc. The data translation layer in Ranger™ then converts the data so gathered into formats as required by the various modules in Ranger™. Ranger™ has the capability to link to the SS7 platform and utilize SS7 messages for efficient and real-time fraud management.
