Confidential, Arlington Heights, IL

Lead Consultant

Responsibilities:

• Designed this to be multi-threaded server, to accept client request using a predefined TCP/IP socket and port. The call- processing payload cards triggers events on the server side by sending IP data to the Proxy server’s listening socket. Also on the server side, events like data value change, alarms raised, critical error reported etc would trigger callbacks, which the Proxy Component receives and sends out the info to the play load cards through IP data packet.
• Designed and implemented with the capacity to handle high volume information transfer by taking full advantage of HAP’s high availability and to handle multiple play load cards requests.
