Senior Consultant, Advanced Software Engineering Pty Ltd (1997 - 1999)
Amongst a variety of assignments during my time with ASE, major clients included Qantas and Woolworths. I assisted a Qantas software infrastructure team as they migrated from CSP to VisualAge Generator. In particular, I taught members of the team the fundamentals of the Smalltalk programming language. For Woolworths, I managed a team of ASE consultants as we developed a Bank Reconciliation system using COBOL/CICS/DB2 and demonstrated the value of Micro Focus software tools. Within ASE I managed the improvement of business procedures as part of the implementation of a Quality Management System. I also provided pre-sales support for Object-Oriented development tools such as VisualAge for Java, Toplink for Java and Simply Objects.
Earlier Positions (1983 - 1997)
In my early years as a professional programmer I used technologies such as PL/I, COBOL, IMS, CICS and DB2 on IBM mainframes. Having started in the IT industry as a trainee programmer for TNT, I moved on to work at IBM Australia where I gained project management experience. During 1988 and 1989, an overseas working holiday included the chance for me to work as a contractor at Lombard North Central in Redhill, UK. Continuing contracting on my return to Sydney, I provided services to major corporations including IBM, Woolworths and Westpac.
From about 1992 onwards I began exploring Object-Orientation and Internet technologies in my spare time. From an OO programming perspective, I began with Smalltalk and later moved on to Java.
I hold a Bachelor of Science from Sydney University and am a member of the Australian Computer Society and the Association for Computing Machinery.
