eServGlobal (09/2001 - 05/2002): eServGlobal
Ltd. is a telco system integration company. In Professional Services team, my
role was to apply consulting skills to evaluate how emerging technologies may
be used for new business revenue streams in the telecommunication industry. In
one of the key projects, I was engaged in the design and evaluation of an EAI
architectural framework that eServGlobal had developed for an important
customer, COMindico. We also
designed and implemented a Channel Support System (a Web portal) for COMindico
and integrated it with their Business Support System (BSS) applications. The
solution was based on the JMS technology, using BEA WebLogic application server
and an integration server (BEA Process Integrator).
We
also evaluated a few message-oriented middleware (MOM) technologies (e.g.,
TIBCO Rendezvous and JMS-based SonicMQ) to evaluate the best option for our EAI
solution. In another concurrent project, based on SEI Architecture Trade-Off
Analysis Methodology (ATAM), I also developed and implemented an architecture
design and evaluation methodology for designing end-to-end enterprise-wide
architectures and systems for eServGlobal’s clients. I lead architectural level
reviews for COMindico in a consulting capacity.
My
other responsibilities included analysing customer's business requirements in
designated subject areas, designing systems to meet the customer’s
requirements, reviewing the BSS plan with the view to how IT may enable the
requirements. I was one of the primary stakeholders in developing options for
consideration in Product Design plans and Technology Management plans. I had
developed concept designs for a few novel products for mobile carriers. In
addition, I also reviewed other strategic plans and identified:
·
what technology changes or improvements
were required to meet the stated service goals,
·
environmental issues impacting the
solutions,
·
business process changes that were
required with the implementation of the solutions,
·
dependencies impacting the solutions and provided
a full analysis of the risks and issues,
and recommended
critical non-functional components for the future.

Jan’01-Jul'01: An application
integration project for Deloitte
Touche Tohmatsu (DTT).
Besides winning the project for Beacon IT, I was engaged in overall technical
management, architecture design and QA roles for a Web-based Electronic Partner
Information Centre (EPIC) using Microsoft technologies (SQL
Server 2000, ASP, and IIS). The EPIC system, launched via DTT’s extranet, is a
highly secured data
integration and business process
reengineering application. The
data was extracted from various sources including PeopleSoft HR and other silo
applications, and consolidated as one version of truth. The team consisted of 6
Beacon consultants and 3 Deloitte staff.
Jul’00-Jan’01: An innovative product development project for TimeCube, Inc, a subsidiary of Beacon IT Japan. Managing a team of 8
engineers, I architected an interactive search and analysis tool called TimeFrame. The
front-end was a thin JAVA client application (built from scratch
using SWING components) and the middle tier was a J2EE-compliant servlet engine
(Apache Tomcat 3.1). This, in turn, was integrated with the temporal data
warehouse management system, called TimeCube Vista.
The backend connection to TimeCube database was via JNI and RPC. The project
team consisted of a few programmers, a SWING contractor and a DBA, who all were
responsible for the development of the highly interactive GUI client and server
for the TimeFrame technology. My other tasks were allocation of
personnel to the project and management of development schedules.
The TimeFrame product and my team also won an Australian
Innovation Award in the Business Software Solutions Category at the
World Congress on IT 2002, Adelaide.
As the Software Architect on
these Beacon projects, my responsibilities were to:
1.
Analyze, design,
develop and maintain shared software components with standardized interfaces,
including complex user interface design and UI architecture.
2.
Provide
direction in development of object-oriented core competencies, methodologies,
coding standards, naming conventions, etc.
3.
Promote and follow
software engineering best practices including all phases of the software
lifecycle and development of appropriate artifacts (e.g., functional
specifications, diagrams, etc.) necessary to understand the designs.
4.
Coach and mentor
less-experienced engineering staff in the practice of software development.
5.
Lead
architectural code reviews, ensuring architectural cohesiveness and overall
consistency through the development effort.
6.
Prepare standard
documents and documentation templates.
7.
Exhibit continuous
focus on keeping abreast of new technologies.
8.
Attend conferences
and seminars, follow current literature, and maintain membership in important
organizations in order to stay appraised of current technology trends and assess
their impact on ongoing projects and future projects.
From time to time, I also consulted with Beacon
Group’s product planning and business development teams (e.g., a Web portal, International Equities Exchange from Jan’01
to Aug’01) to understand their business needs and to set directions and
staffing levels accordingly. I gained strong experience in setting vision for
software architecture, technical infrastructure, and solutions based on other
technologies from third-party vendors such as Microsoft, Comshare, Knosys and
Oracle.
CSIRO (09/1999 - 07/2000): Besides applied R&D,
our software architecture group provided highly specialised consulting services
to various businesses and government sectors in distributed software
architectures and technologies:

prototyped a distributed architecture for NSW Roads and Traffic Authorty’s
monitoring and management system. Prototypes of candidate publish-subscribe
technologies (MQSeries, TIBCO, OrbixTalk) were used. Evaluated against a set of
application-defined criteria, including rigorous performance testing.
4.
Participated in
several Middleware Technology Evaluation projects.
I also initiated and lead a strategic research program in Enterprise
Application Integration (EAI) methods and technologies at CSIRO. We developed core
competencies in the area of “Distributed
Object Systems and Component-Based Architectures for EAI” and analyzed
synergies between advanced Java technologies
(in particular, EJB and servlets), CORBA and XML for enterprise
application integration solutions.

System. The PeopleSoft Message Agent API was wrapped as a LotusScript Extension
(PeopleSoft LSX) and calls were made directly into the PeopleSoft clients DLLs.
PeopleSoft's client used BEA's Tuxedo to send messages to the backend Oracle
database through the application server. Supervised and managed the project.
·

consulting. I managed and developed Web interfaces using Java-based forms and
servlets to access the backend Sybase SQL databases for the Work Request
System of a prestigious client. Security and authentication aspects were
given high priority.
E-commerce Web site for a client, offering Web-based export documentation for exporters and banking institutions. Solution used Java (Oracle JDeveloper) to implement POP and SMTP protocols for the purpose of remote printing and mail processing of export documents on the server side. TotalSoft was engaged in the full life cycle of the project.
Distributed Software Project Management Tool - A groupware
application developed in 1999 for managing resources of a distributed software
project. This was an independent self-created tool. In 2000, this tool was
further enhanced as a second prototype to include task and team management
modules in the DSPMtool. Skills used: Project management, business
analysis and software development, Visual BASIC 6.0 and COM/ActiveX. Presented
this tool in two conferences in the US.

very first job, I was responsible for the creation of an Information Management
System to handle the inquiries from the top management and the Indian Ministry
of Petroleum Industries. I developed and maintained software for ONGC's Long-Term
Corporate Plans (1990-2005), which dealt with its physical and financial
projections (exploration, drilling and costing plans). These systems (developed
in COBOL and BASIC) run on DEC 2050 and IBM 370. I also developed a database
for monitoring the status of Foreign Exchange Release Cases for joint venture
projects of ONGC.
At ONGC, I also worked as a responsible team member for two R&D projects “Estimation of Discovery Cost and Production Cost of Crude Oil and Gas” and “An Optimizing Model for Exploration and Exploitation of Hydrocarbons in India.” This role involved substantial liaison with the consultants and statisticians from the Indian Statistical Institute, Calcutta and overall management of the projects.
