· Developed primary user interface for NAS product using Java applets, Java applications, and developed server side networking modules in C.

· Developed full featured tape backup software for kernel and NetBSD using TAR, including user interface, automatic scheduled backups, and restores.

· Developed full-featured NDMP v3 Server for embedded kernel and for NetBSD.

· Developed client side java application to discover NAS servers on a network, allow the user to configure them and view status information. Designed and developed server side discovery and configuration protocol modules in C.

· Developed system logging and monitoring using C, HTML and JAVA. Developed server side post mechanism over HTTP for user interface.

· Developed network socket layer interface to network driver for NAS kernel, including read, write, open, close, listen, bind, accept, connect, select and poll.

· Fixed and improved TCP/IP stack of embedded kernel.

· Fixed and improved CIFS layer, added domain controller interface and user/group importing, locking, MD4/DES password encryption, group support, subnet support, and MAC support.

· Developed an ‘rdate’ server for NAS kernel.

· Developed support for simultaneous backup processes to multiple tape devices and support for jukebox robotics.

· Developed read ahead mechanism to increase backup performance and maintain data stream to tape devices.

· Developed user interface pieces for NetBSD using PHP and JavaScript, including event notification, NDMP, and backup setup.

· Developed E-Mail, and SNMP notifications module for NetBSD and kernel.

· Developed protocol and server module for delivering status information regarding server performance/load, network and drive usage statistics and more.

· Created network testing procedures and programs for Windows, Linux, Solaris and BSDs written in C, Java, PHP, DOS Batch, and Unix scripts.

· Designed and developed windows program to test NAS device for data integrity and performance in Visual Studio .NET – Visual Basic.
