In the first years of this role, I successfully delivered the upgrade and operational transformation of the bank's highest-volume Java platform. Based on the lessons learned, I authored a comprehensive Enterprise Java Hosting Strategy, which addresses transformation of the bank's fleet to a more simple and sustainable model.This involved engaging with disparate parts of the IT function (CTO, infrastructure, development and engineering) and creating a coherent approach that addresses the true pain points of running the fleet.Having gained endorsement and funding for the strategy at the GM level, I created the entire architecture of the resultant Platform-as-a-Service and assured delivery in a complex multi-bank landscape with significant out-sourced components and engaging ~20 development teams and several operational and project teams to deliver 350 servers for existing and new applications. I also delivered all key technical assets, the engagement process and operational models and transitioned the platform to a BAU service.I brought the disciplines of my extensive software development background to bear on the process too, assuring that all software (in several languages), configuration and automated processes are source-controlled, continuously built, testable and versioned. The next evolution of this service this service is to make it available in commodity IaaS cloud environments and to provide a Docker-ready version. Both ot these were anticipated by the strategy and I have prototyped both for further development. Show less

An existing pricing core, written in J2EE, was extended and enhanced to accommodate the needs of the Australian Market while it was enhanced to be a core platform for FX trading.Key integration challenges included reflecting trades to an unreliable deal booking system (Quantum) through asynchronous messaging, and providing intranet web-based applications to leverage the quoting and dealing capability. These were based on a blend of existing J2EE components as well as Spring, Hibernate, JSF and AJAX technologies (notably mixing fit-for-purpose components from the RichFaces and DWR frameworks). This allowed for extremely rich behaviours through standard browsers enabling real-time notifications to and interventions by dealers.Another challenge was providing a highly-available service interface to the same platform to provide FX banking services through BankWest's Corporate and Retail Internet Banking System. I drove the architecture and design of this interface drawing on the best practice SOA experiences developed over several years. As a result, this functionality was delivered in a very short time while maintaining facets of quality, availability and evolvability. Show less

Initially engaged by the business, my role was to define the solution architecture for a contemporary product platform in the superannuation/pension and investment space. This was to be based on providing Wrap and SMA like features to the mass market within a Superannuation structure.As it became apparent this would be a major strategic enterprise initiative costing tens of millions of dollars, the role of Principal Solution Architect was created and filled by AMP.

I worked closely with him and others in refining, documenting and promoting the solution architecture and in exploring other Solution Alternatives in a rigorous manner as the business clients changed emphasis and direction.Feedback to the business users on their strategy, direction, process reengineering, strategic technology choices and vendor negotiations were common; in the pre-implementation phase close collaboration between business and IT was pursued.As part of the project, a Proof of Concept was initiated which included the preparation of a repeatable development methodology and which used Spring, Hibernate, Maven and related tools. This was a significant extension to my comprehensive experience with Java toolsets. Show less
