- Credit Lending Application for Close Brothers using Power curve Originations, an inhouse product. The project requires integration with external 3rd party APIs and Close Brothers APIs with the screens developed in Power curve. Power curve provides options to incorporate java scripts into the screens. I had proposed and implemented a suite of microservices to integrate with 3rd party APIs.

09.2009 - 04.2012
- A series of projects necessitated as part of integration of Halifax and BOS with Lloyds Bank. As part of the integration of the three banks, there were several initiatives taken. The initial state was to uplift applications running in older WebSphere /MQ versions to latest stack. A high-level decision for integration was to use the single codebase for Retail branch application across the brands. Based on the nature of the application and expected volume, it was decided for some applications there will be a separate instance per brand while for some applications all brands share a common instance. This necessitated creation of new environments and validate their connectivity with new backend systems and middleware systems and hence an environments team. A new branding application was created to determine the display and routing brands based on branch which will be consumed by the Retail applications for display and routing to appropriate instances.
