PrimeCo PCS, LP                                                October 1996 - November 1999

Software Consultant

 

• Designed an AKEY management system which interfaced with the mobile switching center (MSC) to provide real-time customer authentication on CDMA traffic. The interface provided middleware connectivity between components which relay transactions from the customer care system, the OTAF, the AKEY system and the MSC. The system was written in Visual C/C++ and used DCE pthreads, RPC and UNIX remote shell commands to provide a low-performance impacting interface to the MSC.
• Re-wrote the corporate commission system used to pay the direct salesperson based on handsets and services sold and maintained. The existing system ran for 40 hours using PL/SQL and UNIX shell scripts on a SPARC 4000 at 95% capacity. Used Pro*C and PL/SQL for the processing component, added error handling and performance tuned the Oracle 7.3 database and SQL queries (example: using cost-based vs. rule-based processing, indexed vs. non-indexed keys, minimized the use of wildcards, etc.). The resulting performance hit was 8 hours (500%) in total.
• Wrote a sales transaction audit system to automate and insure transaction correctness and completeness from the POS interface at the stores to the accounting general ledger. Used Visual C++ 5.0 and Visual Basic 5.0 and DCE to move data throughout network.
• Also worked on a follow-on project for OTA (as shown previously) to add the capability for a cellular subscriber to download the latest preferred roaming list over the air in real-time. Using Sun OS 5.4 and Oracle 7.3. This process also interfaced with a Patrol backend agent through the use of the Patrol Event Manager API’s.
• Managed and worked with a team of software engineers to develop the PrimeCo check billing system whereby a customer can call into a VRU (Voice Response Unit) and retrieve balance information regarding their account. The system was written in Visual C/C++ and used DCE threads.
• Software manager / lead developer for a project using Unix/Sun OS 5.4 and Oracle 7.3 for the corporate customer relationship management system (CRM). The software is used to handle back-end interfaces between Scopus, P2K, Tuxedo, Siebel & Siebel Tools, VerSatility and PeopleSoft business applications. These application interfaces provided a layered architecture for customer account storage and retrieval, warehouse volume analysis and inventory, customer billing, and phone activation requests. The middleware made it possible to integrate these diverse clients together with otherwise incommunicable parent applications.
• Also built a system using MQSeries with TCP/IP from the client and the Java Native Interface for connecting customers to backend systems using Oracle Financials and Oracle Manufacturing for reports and logistics. This also helped managers keep track of sales volume through a web interface.
• A third project included back-end functionality to a Visual C++ order entry application running on Win ‘95/Windows NT 4.0. Abstract data collections were passed to and from the client through a layered UNIX system to Oracle 7.3.2 using Pro*C/C++ Methods 3 and 4. Rational Rose was used to design the system at the class level, providing a basis for the entity relationships. The back-end system covered the following areas:
  • Stored procedures wrapped in a generic package
  • Objectized relational data modeling using over Oracle
  • A variety of implementation-specific integrations
• In addition to combinations of Visual C++ front-ends and UNIX back-end work at the transport layer, also provided a generic “objectized” database interface to the Oracle database where a C++ order object could be passed into the system and a collection of objects returned to the calling methods. This business application proved to be a vast improvement over the existing order management system so that drill-down could occur for each item in a given order including its lot number, location, electronic serial number, etc. over a distributed system (a client anywhere in the United States could check the status of any system component or its inventory).
• Also performed many web development projects using Visual Basic, VB Script, Java, Java Script, SQL Server, Rapid SQL, and ASP. A separate project included producing a cross-platform billing system which used a CORBA-like environment of Java Server Pages, Java front-ends and HTML running on a Linux Apache server. This system also interfaced with an Oracle database for retrieving and storing customer records. Crystal Reports was used on both projects as the reporting tool for management.
