• Co-designed and developed a new user interface using Polymer and JSON servlets to create an integrated forum within the core product, improving user interaction and platform integration.

• Collaboratively engineered a next-generation search engine UI using YUI3 and YUI2 components, connecting to JSONP servlets to enhance the user experience and search functionality.

• Developed and maintained a J2EE/Struts-based search engine (Universal Search), resulting in increased search efficiency and improved data retrieval processes.

• Enhanced and supported a J2EE/Struts-based order/invoice processing system (beX), optimising business-critical operations and reducing order processing time.
