Professional Experience

• Managed the UNIX servers, consisting of C, D, J and K Class systems running HP/UX 10.20 and 11.0, and Sun UltraSparc servers running Solaris 2.6.
• Managed the desktop UNIX systems, consisting of C, D and J Class systems for the application development engineers.
• Managed the Sendmail, NFS, NIS, SAMBA, Apache and Netscape Enterprise web servers.
• Installed and configured Oracle 8 Database for a development venture between Oracle and Agilent engineers.

• Installed, configured and maintained the co-location servers, consisting of Sun E4500, E420 and Netra T1 systems.
• Installed, configured and maintained the co-location network components, including Cisco Catalyst Switches, 3600 series Routers and PIX firewalls.
• Installed, configured and maintained the unix development servers, including Sendmail, NFS/Automount, CVS, NIS, SAMBA and DNS.
• Implemented a unix development environment with GNU and other popular tools including gcc, g++, gdb, ddd, make, flex, bison, Perl 5, etc.
• Installed and configured Oracle 8 and MySQL databases for development and production use.

• Maintained the engineering lab UNIX servers, consisting of Sun Sparc 20, UltraSparc 1, UltraSparc 2, E250 and E450 systems running Solaris 2.6 and Solaris 7.
• Maintained the engineering lab desktop UNIX systems, consisting of Sun Sparc 2, 5, 10, 20, UltraSparc 1 and UltraSparc 2 systems.
• Designed and implemented a Solaris JumpStart server with a custom web interface, written in HTML, for the engineering lab.
• Maintained the engineering lab network backbone consisting of Cisco Catalyst 5500 and 7200 Switches with Router modules.
• Played key role in the process of moving the engineering lab, consisting of nearly 600 systems and the engineering network backbone, to a new building in a single weekend.

• Managed network of nearly 300 HP A, B, C, D, G, J, K and N Class systems running HPUX 10.20 and 11.0. Many of these systems were Multi-Way High Availability servers.
• Designed and implemented a new lab-wide application server. Downloaded, configured, built and installed nearly 300 GNU and other FSF applications for 10.20 and 11.0 platforms. Designed and implemented NIS Automount Map configuration to automatically mount the correct set of applications based on native OS. The new application server brought all applications into Y2K compliance and eliminated the need for multiple NFS mounts and a confusing set of wrapper scripts and symbolic links.
• Redesigned the UNIX sendmail configuration for the lab. This effort resulted in dramatically improved email performance and the elimination of mail spool file locking problems.
• Developed a plan to move the compiler design lab to using NIS and automount maps to reduce NFS related system hangs and improve overall network and system performance lab-wide. A side benefit of implementing NIS allowed the lab to conform to corporate security requirements.
• Investigated and solved long-standing high visibility problem with the deployment of the Envizex and Envizex II X terminals. Crucial lab budgetary considerations hinged on this effort.

• Maintained the SGI systems running Irix 5.3 and 6.X including Personal Iris, Indy, Indigo, Indigo 2, O2, and Multi-Way Origin and Challenge systems.
• Maintained the Sun systems running SunOS 4.1.x, Solaris 2.4, 2.5.1 and 2.6 including Sparc 5, 10, 20 and UltraSparc systems.
• Developed and implemented a solution to the problems with the Amanda system backup software.
• Transferred NIS master and DNS functions from aging Sun 3 to a Sun Sparc running Solaris 2.6 without service interruption to the lab.
• Transferred another NIS master server from an aging DEC workstation to an SGI running Irix 5.3, without service interruption.
• Solved long-standing problems with the system backups.

• HP/UX pre-release system testing using test routines to test the functionality of the major subsystems of HP/UX.
• Performed OS installations and configuration for test ring setups.
• Created test scenarios for testing NIS, NFS, DNS and other functionality of the OS.
• Performed various tests on the major subsystems to find Y2K problems.

• Installation, configuration and upgrade of SGI systems running Irix 5.3 and 6.X including Indy, Indigo and Indigo 2.
• Installation, configuration and upgrade of Sun systems running SunOS 4.1.X and Solaris 2.4.
• Administration of PC systems running FreeBSD.
• Planned and implemented the hardware and software upgrade of the company Auspex NFS Server which proved to be a significant undertaking.

• Managed the Sun systems running SunOS 4.1.x and Solaris 2.4 including Sparc 4, 5, 10, 20 and UltraSparc systems.

• Managed the corporate Network Appliance NFS filers.
• Installed and configured Xinet software to allow MAC users to mount UNIX volumes eliminating dependence on the Cayman Systems Gator boxes.
• Eliminated long-standing problems with the NIS master server, Sendmail system and HP network printers.

• Maintained network of over 50 Sun and SGI systems running SunOS 4.1.x, Solaris 2.x and Irix 4.X to 5.X respectively.
• Maintained several UNIX variants including Pyramid, Ridge, Convex and Dec VAX systems.
• Implemented network wide backup strategy for all networked systems using Amanda.
• Installed and configured Sybase databases.
• Converted "sneakernet" to ethernet by running the first thick coax for networking at ABC.
