07-98 to 02-03: Project Manager / System Architect / System Analyst /

Software Developer

AT&T Wireless Services / contracted through Adecco Technical

. {Project Management} Managed team of seven people in a web based, back

office retail IT project which included project scheduling, enhancement

prioritization, budgeting, task assignments based on assessment of

skill sets, and proposed enhancements to clients based on ROI, and

technical oversight.

. {Business Process} Wrote change proposals that documented how client's

business flow would be modified and documented intended improvements to

allow tracking of results. As subject matter expert, reviewed,

corrected and clarified change proposals written by other functional

analysts. Interviewed retail back office transaction management teams

to gather business flow information, and based on that information,

provided management with proposals to automate business processes.

Negotiated technical details with client retail IT organizations to

achieve solutions with regard to merging transaction flows for

automation.

. {System Architecture} Developed and constructed the complete system

architecture (including hardware, software, and networking

requirements) for the Transaction Automated Processing In Online

Convergys Accounts (TAPIOCA) system. Previous to development of this

system, the client was manually processing customer payments received

in retail stores, and the client was unable to bill equipment sales to

customer's accounts, and an automated customer upgrade program did not

exist. At final configuration of the TAPIOCA system, over 700 retail

stores sent their customer account payment transactions to TAPIOCA for

processing into the billing system. The ability to bill equipment sales

to customer accounts (instead of requiring some form of payment at time

of sale) allowed the client to sell additional equipment in retail

stores, develop an automated customer upgrade program, and use the

TAPIOCA system as the company-wide standard method to process all

transactions that involve equipment sales billed to a customer account.

Sales volume that was previously unrealized before the existence of the

TAPIOCA system exceeds one million dollars per day. Total transaction

volume processed by the TAPIOCA system to date exceeds one billion

dollars. Total TAPIOCA project development, maintenance, and operation

costs to date are estimated at 700,000 dollars.

. {Requirements Analysis} As TAPIOCA subject matter expert, collaborated

with functional analysts from various client business units to write

functional requirements documents with regard to back office processing

of customer transactions. Provided technical oversight and editorial

support of various technical documents detailing retail billing system

enhancements and modifications.

. {Software Development} Designed, developed, tested, and deployed the

TAPIOCA software which performs normalization and controlled transfer

of customer monetary transactions and provides controlled transfer to

the Macro/Cell billing computer to allow accurate automated billing of

customer transactions generated by over 700 AT&T Wireless retail stores

and call centers using Digital Alpha, Intel PC, Digital Unix, Microsoft

Windows, Microsoft Visual C++/Developer Studio, Borland JBuilder Java,

Visual Basic for Applications, Borland VisiBroker CORBA, XML, Oracle,

Sybase, Progress 4GL.

The TAPIOCA application is written in a combination of C/C++ (using

Microsoft Visual C Visual Basic for Applications (running inside a

Reflection terminal emulator), and Borland JBuilder Java over Windows

NT/2000.

The C/C++ code accesses customer transactions, which are acquired from

various business sources. These data sources include AT&T Wireless

retail store data servers, data servers sourced by B2B sales channels,

and data servers sourced by internal sales channels, such as the

Customer Upgrade sales team. The C/C++ code communicated with these

various data servers via FTP and remote SQL data access to acquire the

customer transactions. The upstream data servers were running on a

variety of platforms, which were typically Unix-based (Digital Unix, HP-

UX, Sun Solaris, etc.), and the databases on these data servers were a

variety of different database types, including Oracle, Progress 4GL,

and Sybase. The C/C++ code normalizes the customer transactions to

ensure data validity and compatibility with the target Macro/Cell

billing system. The C/C++ code controls transaction data flow to the

portions of TAPIOCA that perform actual posting into the billing system

(written in Visual Basic for Applications). The portions of TAPIOCA

that handle the web-based manual transaction correction interface

(written in Borland JBuilder Java) allow correction and reprocessing of

transactions with incorrect or missing data. The C/C++ code performs

logging functions to provide daily logs of transactions processed, and

also interfacing to the enterprise wide data warehousing system to

provide that system with transaction processing results. Because

TAPIOCA is a multicomputer application, the C/C++ code performs

clustering control to ensure that no individual TAPIOCA server remains

in an inoperable state without automated notification via e-mail/paging

to production operators. This clustering capability also provides

automated load balancing to ensure timely transaction processing.

. {Production Operations} Performed the daily production operation of

the TAPIOCA system to process customer transactions. Provided 24/7/365

support on a continual basis to ensure that the TAPIOCA system could

provide timely posting of customer transactions. Performed backpatching

of transaction data and reversal of transaction postings in the event

of an error in the transaction data provided from upstream systems, or

an unannounced fatal change in the downstream billing system. Designed

and wrote enhancements to the TAPIOCA system to automate these

transaction data backpatching processes in real time to reverse

erroneous billing postings before adverse customer reaction could

occur.
