Depending on my current schedule and prior commitments, I may be available for short-term freelance or longer term contract work. You can contact me by email at firstname.lastname@example.org to discuss your needs, and the ways I can help you.
UNIX SysAdmin and Integration Services
I can provide UNIX Systems Administration services, including installation, modifications and upgrades, performance tuning, and general support for Oracle/SUN Solaris, Linux (Oracle, RedHat, CentOS, Mandrake, Debian, Ubuntu, and many others), Mac OS X, and IBM AIX. Most of my 20 years experience has been with Solaris and Linux.
Aside from general UNIX SysAdmin services, I also specialize in the integration of UNIX system services (Bind, SNMP, SMTP, FTP, OpenVZ, etc.), web-related applications (Apache, MySQL, WordPress, etc.), and operational applications (monitoring, ticketing, etc.).

Sample Open-Source Projects
Most of the code and applications I write are custom, and cannot be shared with the Open Source community. The following are some of the exceptions, that I continue to maintain in my spare time. I also frequently publish code snippets and UNIX related content on Surnia Ulula.
check-httpd-limitsPerl script to compare the size of running Apache httpd processes, the configured prefork / worker / event MPM limits, the server’s available memory, and project the maximum memory usage by Apache httpd.
otrs-ticketPerl script to create and update OTRS tickets from Centreon, Nagios, the command-line, or other monitoring tools.
NextGEN Facebook OGPHP (object-oriented) plugin for WordPress to add Open Graph meta tags for Facebook, Google+, LinkedIn, etc., plus social sharing buttons for Facebook, Google+, and many more.
Website Development and Hosting
On a Freelance basis, I may be available to install, configure, modify, customize, and integrate a UNIX-based website infrastructure. Depending on the size and scope of the infrastructure, this may include load balancing, content delivery (CDN), back-end/front-end caching, replication, disaster recovery, cloud services, custom Perl and/or PHP code, etc.
