Confidential, San Jose, CA

Consultant and Software Engineer

• Soft switch was successfully deployed to Yahoo BB in Japan, Hutchinson in Hong Kong, Reliance in India, CableVision in New York. Load monitor daemon and heartbeat daemon are responsible for monitoring, load distribution and fault avoidance.
• Used H.323, SIP VoIP protocols, and Jabber/XMPP to support instant messengers, chatrooms, and group voice chat.
• Designed a security key exchange server using TLS/SRP for client/server security. (C++, SSL, TLS/SRP, Linux, socket programming)
• My patent is about how to use stateless protocols to select least-cost routing and least-loaded Cisco gateways. That essentially minimized service downtime.
• Created an IMS / user/subscriber management server with the capacity and scalability to handle millions of clients, and developed Reliable Data Protocol (RDP, rfc1151) v2. (Linux, C/C++, MySQL, LDAP, SNMP, PHP)
• Developed a provision server for provisioning client devices. (C++, MySQL, Oracle)
• Developed MGCP/SIP/ISUP translator/trunk controller (MGC) for interoperability between SIP softswitch, Cisco trunking gateways, and PSTN. (C++ on Linux)

Confidential

Sr. Software Engineer

• Developed client/server distributed applications for manufacture production tracking system, data warehouse repository servers, and operation data storage. (UNIX, Windows, Oracle, HP Tandem NonStop SQL, and Sybase)
