One Bill (Shaw) Project

June 2011 April 2012

TELUS wanted to offer its customers the ability to request a single bill for their mobile and wireline

services (landline, cable, and internet). To achieve this TELUS needed a system that would not only

consolidate customer information from all these services, but that would relay this information to its

customer service representatives quickly and seamlessly, to allow them confirm the service while

still on the phone with the customer. To consolidate its customers across its wireless and wireline

billing systems I, along with a team of three developers:

• Interacted with the clients to gather business requirements

• Developed web services to:

Validate and format customer billing address for bill presentment

o

Consolidate billing name/address and bill cycles across wireline Amdocs

o

Enabler and wireless Amdocs Knowbility (Ensemble) billing systems.

Add bundle discount to qualified consolidated customers

o

• Modelled business processes using OSB proxies and business services.

• Exposed the webservices to the Enterprise Service Bus using Oracle OSB.

• Customized the OSB services for deployment to AT, PT and Staging environments

• Set up and configured Weblogic JMS modules for asynchronous messaging

• Deployed the web services onto Weblogic Server

• Deployed the ESB services to Oracle OSB server

• Tested the ESB and web services using soapUI and Service Manager

Project Imagine is a TELUS initiative to redesign its systems and processes to enhance its

operations and profitability within the Telecommunications consumer market. Part of this

transformational change included the upgrade of its Billing system to Amdocs Enabler. Being a

huge project that spanned over 5 years I was involved as a Java developer and Production support

lead for a couple of sub projects/applications.

Financial Gateway (FGW)

Amdocs Enabler out of the box General Ledger (GL) implementation failed to meet

TELUS’ journaling needs so Financial Gateway was created to fill the gap. Financial

Gateway provides a common gateway through which Amdocs Enabler billing/Accounts

Receivable (AR) records can be transformed and summarized for classification and posting

to SAP.

• Provided impact assessment of proposed code changes and fixes to defects

• Worked closely with Business primes to elicit business requirements

• Engaged in build and continuous integration management

• Implemented new change requests, (CR) to support new application

features

• Maintained and extended the rule engine to capture complex business

rules required to transform and summarize billing extracts from Amdocs Enabler

• Conducted defect root cause analysis and recommended solutions

• Participated in defect triage and change management meetings

• Designed and implemented batch workflows using Control M job

definitions

• Created and extended Control M batch jobs as part of EOD (End of Day)

map

• Designed and developed Control M batch jobs and scheduled them to run

automatically as part of EOD/EOC (End of Cycle) job map

• Fixed code defects and provided Production support

• Performed end to end system tests

Technologies/tools used: J2EE, JUnit, Syncsort, UNIX shell scripting, Control M, PL/SQL,

SQL Loader, log4j, Amdocs Extract tool, Maven, iBatis, Spring, Oracle database, XML.

HSIA Usage Rating

This project’s objective was to track high speed internet access (HSIA) over usage on

TELUS network and allow TELUS to bill clients for over usage as well as make informed

decisions to address network capacity issues.

My responsibility was to build a batch application that will run daily to retrieve customer

and product information from billing operational databases and identify and report billing

accounts that have reached their usage limit. To accomplish that I:

• Retrieved billing account information from customer database

• Retrieved high speed internet product information via EJB

• Merged product and billing account information to retrieve data relevant to

the application

• Developed, tested and scheduled the application as a batch job that runs

daily as part of a job map

• Provided production support – through defect analysis and resolution

after the project went live

Technologies used: J2EE, JUnit, Syncsort, Maven, UNIX shell scripting, Control M, iBatis,

Spring, log4j, Oracle database, XML and EJB.

Financial Gateway Error Management

Errors encountered while transforming billing records in Financial Gateway’s RuleEngine,

prior to Imagine project phase 2, were written to file and required manual modification to

fix and re process. This manual process was error prone and didn’t meet SOX compliance.

A web based GUI error reporting and management application was therefore proposed as a

solution.

Along with another developer I:

• Developed and scheduled a batch job to load billing error records to

database

• Exposed database CRUD operations as EJB services

• Developed and scheduled a batch job to retrieve corrected error records

from database.

• Designed, implemented and tested the web application

• Enhanced Financial Gateway RuleEngine in order to reprocess corrected

billing error records.

Canpages Billing

The purpose of this project was to enable third party billing by TELUS of one time

monthly directory advertising charges for Canpages, a directory service provider. This

allowed TELUS to bill its business customer directly for Canpages advertising usage. It

required building an application that will serve as a file transfer hub between TELUS

External SFTP Gateway server and its Mainframe servers in British Columbia and Alberta.

To realize this I:

• Wrote file watch scripts to monitor and alert the availability of

Canpages billing files on the SFTP Gateway server

• Modelled and developed a workflow process to encapsulate the

handshake communication required between the servers.

• Integrated the workflow process with Control M for automated

scheduling and execution

Technologies/Tools used: J2EE, JUnit, UNIX shell scripting, Control M, Maven, XML,

Spring.
