Java-J2EE Developer

Responsibilities:

• I was a developer in the team that worked on the following listed projects. I worked on the design and development of following project enhancements.
• Same Agent Handling - The solution was built using the Genesys routing engine and Java/Oracle customizations to route customer responses to agent responses to the agent who sent the original response.
• Average Handling Time - This was built in Java/JSP/Struts framework/DHTML/Oracle. This involved customizing the Genesys Desktop thin client provided by Genesys to track the handle time for every email handled by the agents using Genesys Desktop.
• Auto Suggest Tool - The AST tool was embedded into the Genesys decision making engine. This would suggest relevant canned responses to the agent based on the content of the customer email. This was built in Java and used the Genesys proprietary BBNiKnow suite. I received a patent in July 2010 for this solution.
• Multi Channel Routing implementation - This was a major upgrade that was performed on the ERMS Genesys system that would allow integration of email, chat and voice media in a unified Genesys ERMS platform. Chat was trialed by a call center in Novas Scotia. This implementation allowed the same agents to work on emails, chat and voice calls using the Genesys ERMS.
• High Queue Warning - The HQW report was built in Java and PL/SQL and sent out email warnings to call center managers about emails exceeding SLA sitting in their queues.
