Summary I have more than twelve years of experience in distributed computing, working as both system administrator and design architect. My work has primarily been in UNIX environments, specializing in Linux and Solaris. I've worked with just about every hardware and software platform out there, and feel confident that I can rapidly learn any new platform that I'm presented with. In the past, I've had varied responsibilities including large and small scale cluster systems design, daily troubleshooting, custom OS builds, systems benchmarking, employee and customer training, management of small to mid-sized teams, and being primary liaison with both developers and management staff. My background was originally as a programmer, although I find myself much more comfortable in the role of engineer or administrator. I currently do the majority of my scripting in Bash. I have programmed in Perl, C, C++, Java, assembly and a few other less used languages. I've included a few of my past projects below. Sitesurvey - A program which, given groups of servers to check, and a trusted user, will generate a flatfile database with hardware, system, virtual site, and package information about those hosts and groups. This information is made accessable through a dynamically generated web interface. Written in Bash and Perl. ES Installer - A linux install ISO generator, capable of building preconfigured slice in time versions of Redhat Enterprise Server. Useful for making clones of an existing machine, or installing base ES3/4 when a kickstart system is not available. Written in Bash. FMonitor - A multiprocess SNMP monitoring system capable of polling hundreds of machines a minute. Supports multiple tiers of notification, timeouts on notifications as well as flap protection. Output is written as themable HTML to a centralized monitoring interface. All data collected is cached, graphed, and used for trend tracking. Written in Bash. |
