Confidential CHIEF SYSTEMS ENGINEER

• System Architect for the Cingular Interactive Messaging System Blackberry . Working with BellSouth and RIM helped develop the first Wireless data protocols and messaging systems that would eventually become Cingular RIM's Blackberry products. Optimized the system to serve the required 5 million messages per day. Provided guidance and operations support as needed to deploy a remote disaster recovery site. The following were specific projects and responsibilities:
• Lead member of a small elite technical team that pioneered wireless messaging and data technology. Created protocols, software specifications and platforms that led to the creation of the Blackberry and other wireless data services. Played a leading role in the development of all aspects of the Interactive Messaging Service Blackberry , a revolutionary messaging system that was the culmination of seven years of product development, refinement, enhancement, and implementation.
