• Integrated Paymetrics API for payment gateway integration and tokenized payment authentication
• Implemented custom CMS components
• (items.xml, jsp, impex)

• Implemented Silent Order Post (SOP) using EPX gateway, modified the multi-checkout JSP pages as well as Java code to capture the transaction code, while the browser based gateway integration processed the credit card authorization and capture
• Integrated SAP PI SOAP interface using spring template to consume the service used for pulling pricing information and warehouse integration
• Extended customer service cockpit to provide support order returns and cancellations
• Hooked into the process engine for OMS and integrated asynchronous SOAP interface to post the return confirmation from the customers’ order fulfillment system
• Enabled stock levels which were periodically updated via hot folder integration
• Implemented review pages with Bazaarvoice
• Data was provided using a feed and was translated from XML into objects and the Impex API was used to import the review data into Hybris.

• Development lead responsible for offshore and onshore development teams insuring code quality and best practices are followed
• Elicited information from business to drive requirement discussions, used to design the data model and proof of concept
