As a solution architect, I was responsible for re-designing the Order Routing system into modern SOA architecture. Rationalized complex business processes into set of manageable orchestration and data services components. Designed the state machine and rule engine as a service which could adapt to the agile business requirements. This ensured configuration driven mechanism for status management which otherwise needed code changes and deployment.Designed the rule based diagnostic service leveraging the existing rule engine for proactive issue identification and notification to the support team. This was submitted for patent and is currently under review in US PTO.
