About Me: I am a Programmer and Senior Unix Systems Administrator / Engineer with experience with Redhat, Debian Linux and Sun Solaris at very large scales. I approach systems administration with an emphasis on efficiency and automation, using my extensive programming skills to architect scalable and robust system installations. I have experience in all aspects of large scale server administration: evaluating hardware, hardware and OS installation, remote management, systems and configuration management, software distribution, BCP, metrics, monitoring and 24/7 on-call rotation. I have experience with all the typical internet servers for DNS, HTTP, SSH, SMTP, etc. I have developed complex applications for the web with LAMP (Perl and PHP). I know how to make an installation run smoothly and ensure availability. I am a self starter and I enjoy taking on new challenges and learning.
