Lead
Developer on the downstream-component of Sensis's $100 million
integration project. My role in this project was overseeing the
implementation of the downstream transformation for a specific
product stream (Citysearch) and coordinating with product stake
holders. Citysearch is a J2EE implementation using Spring with
Hibernate backing onto an Oracle (10g) RAC. The core of the
Citysearch application is based around a metadata-driven CMS
(Fatwire) with data access facilitated by load-balanced FAST Data
Services instances. The application logic is deployed to thin
container (tomcat) with centralised enterprise message distribution
coordinated over JMS managed by a Weblogic Application Sever cluster.
The user-services component is a JSP-centric web application, served
by a load-balanced Apache cluster. My role within Citysearch itself
has been to design and implement an enterprise adaptor as a JMS
consumer for message ingestion and transformation of enterprise data
(as XML) into application specific messages for consumption by the
Citysearch CMS.
Other roles within Citysearch involved
redesigning and implementing data ingestion from external data
services providers via XML stylesheet transformation (XSLT) and data
aggregation for services such as Geocoding and map data integration
(via SOAP). The Citysearch project was run as an Agile project with a
heavy TDD focus using JUnit, Cucumber and Hudson

Project Summary:
$7 million greenfield project implementing an administration system for Whole of Life insurance products. Integration with existing legacy systems via SOAP.
Contract with CU Poland. Contracted to build an insurance administration system for Commercial Union Poland. J2EE/Java ground up development, complete SDLC, successful project currently in production and maintenance. I was part of the core design team and was responsible for the UI design and layout and integration with the business logic layer (implemented via a unique hybrid pattern comprising a session façade with a stateless strategy). This design provided a separation between application business logic with transport and allowed the system to operate in either it's full distributed mode through the container (Weblogic) or as a 2-tier application without the container. Other work included designing an internationalization layer which provided “automatic” internationalization of components. Technologies used in this project where Weblogic, Oracle 10g and Kodo JDO/JPA. Group development facilitated through perforce, with ant providing the build and deployment environment. Role: Technical lead and architecture.
Project technologies:
J2SE 1.4, Oracle (9i) and DB/2 UDB400, XSLT, Ant, Perforce
Project Summary:
$8 million greenfield project implementing an administration, illustration and new business system for Whole of Life and Term Life insurance products. Integration with existing AS/400 legacy system via bespoke communications layer.
Contract with American International Assurance. Java/Swing implementation. In-house transaction management system and RDBMS mapping to Oracle. Another SDLC project, successful and still in production. This system was an insurance Administration and New Business System with components for In-force Illustration (of existing legacy policies on their AS/400 platform). Significant architecture components developed for this project where the design of an in-house transaction management system and an in-house Object to database mapping based on CASTOR.

Employer: AFS/TARMS
Clients: Société Générale (Sydney), ABN/Amro (Sydney)
Senior Systems Designer. Early in 1998, I rejoined Applied Financial Services. The position involved building interfaces into the Tibco messaging products ETX and RV. Building these interfaces required adding a distribution layer onto the existing financial product TIB Trader (a deal capture and risk management system). The role entailed designing new components and enhancing existing components of the system. This included a bespoke persistence layer, a deal distribution layer and a deal load and capture layer. I was also involved in the design and implementation of a valuation and pricing component for a Data Warehousing system at ABN/Amro (Sydney). This essentially requires writing an interface to the SCORE system, extracting deals, valuing them and returning the resultant valued deals. All of the work done at Tibco/AFS was in Visual Works Smalltalk with persistence managed by an Oracle back-end.
Project technologies:
VisualWorks Smalltalk, Sybase, Envy/Developer
Executive with Macquarie Bank Limited, Sydney. Senior developer in a large development team implementing a Derivatives and Options trading and risk management system. A Smalltalk (Visual Works 2.0) 3-tier implementation backing onto a Sybase back-end. The software provided Settlement and Risk Management and Analysis for a range of instruments but with specific emphasis on the Options and Equity markets. Most of the work I did at Macquarie revolved around extending existing functionality providing new types of sensitivity variations on stock and other assets.
Project technologies:
VisualWorks Smalltalk, Oracle (7), Envy/Developer
Employer: AFS
Clients: Société Générale (Singapore and Sydney)
Software Engineer with Applied Financial Services. Systems design and programming role developing a Financial Trading and Risk Management system in Smalltalk (Parcplace VisualWorks 2.5.1) for SunOS. The design was client-server, with the client portion implementing instrument capture. This system supported trading for Swaps, Bills, Bonds, FRAs and Futures and provided real-time global position and forward revaluation to traders.
Object persistence was maintained by several server processes, flattening objects and storing them within a relational DBMS (implemented using Oracle 7.3). The main focus of my work at AFS centred around building an instrument importation engine for data conversion (for a wide range of instruments) between existing platforms on client databases.
A second category of development involved developing several server components centred around the ANSI-Sparc three schema architecture. One of these server components handled distributed deal transactions from front-ends and ensured guaranteed DBMS updates, with responsibilities for business transaction management deferred to another server process.
In the last months of my employment at AFS I developed a new server application to manage rate and network configuration. This was a system management activity which allowed administrators to remotely query the status of the network for attached, blocked and connectable front-ends, providing a centralized trade management environment.

Clients: Standard Chartered Bank (H.K.), CBA (Sydney)
Senior Designer with Standard Charted Bank (Hong Kong). Retail banking branch sales system (for demand deposit and term deposit accounts), based in Hong Kong. The focus of the project was specifically within a Branch Sales environment. The implementation was designed to replace the banks' existing 3270 environment, in a three phase implementation. The project was implemented using Digitalk/V Smalltalk with Team/V to manage group development. Within the project, I worked mostly in a technical role, designing and implementing authentication and communication services between the Bank's existing back-end host platform (an MVS environment) and the front-end client applications.
In addition to communications, I was also involved in extending and maintaining the business model that was the core of the application. The implementation of the business model was done using the Footprint Banking Framework which supported Entity, Association, Aggregation, Classification and Generalization abstractions within a Smalltalk environment.
I was also entirely responsible for object persistence, building an object-to-persistence mapping framework and query engine which allowed any set of connected entities to be persistent. Objects could be inserted into any RDBMS and retrieved at a later date, with their connections to other objects and their state intact. In addition, the architecture provided for object identification using surrogate keys, DBMS garbage collection and optimistic entity-level locking. This design provided many of the services of an Object database, except they were implemented in an RDBMS.
Project technologies: Eiffel
Software Engineer in Santa Barbara, California with Interactive Software Engineering working under Dr. Bertrand Meyer. Interactive Software Engineering are the originating authors and developers of the Eiffel programming environment. Much of the focus of my work there was to enhance and extend the Eiffel tool set. Primarily, I worked on developing Eiffel Build, a visual programming interface and application generator and, one of the core tools of the Eiffel suite. The environment used for development was UNIX-centric using Motif/X11. Consequently, I had exposure to many different variants of UNIX, as Eiffel was ported to most of the major UNIX platforms. I was also responsible for network and system administration.
Project technologies: C/C++, Oracle (7), Oracle Forms
Clients: Coles-Myer, Department of Transport and Communications
Consulting Analyst with Ernst and Young Consulting. Implementing data conversion (in C++ ) for a host-to-client server migration project at Coles-Myer. Also worked at the Department of Transport and Communications (DOTC), optimizing embedded SQL queries within an existing application. This involved evaluating and rewriting the queries in canonical form.
Research Assistant within the Department of Information Systems at Monash University. My research activities were mostly centred around object orientation. Most significantly, I was employed by the research group to implement their real-time telemetry simulation using Smalltalk/V on a Macintosh Quadra. In addition to research assistant, I was also a sessional tutor teaching Object Oriented Analysis to 3rd year students and C programming to 2nd year students.
