Senior Linux System Administrator at Adknowledge.
I work as a system administrator as part of a team responsible for over 600
servers running SuSE Linux Enterprise Server on a mix of Dell hardware and
VMware virtual machines. My major projects involve improving and expanding
their Nagios monitoring, centralizing authentication and authorization, and
configuration management.
Jul 2009 - Apr 2010
Contractor at H&R Block.
I was tasked with several projects aimed at improving H&R Block's ability
to manage and audit their HP-UX and Red Hat Enterprise Linux (RHEL) systems.
Drawing on skills gained through the RHCE certification process along with
fifteen years of experience in Linux and Unix system administration, I
accomplished my tasks on time, completely, and without need of supervision.
Here are some of my major accomplishments:
Active Directory integration. I integrated H&R Block's Unix and Linux user account and access management into their existing Windows Active Directory infrastructure. This migration replaced a manual, labor-intesive, and difficult to audit process with one providing centralized management using familiar Windows tools. My implementation used PAM, Kerberos, NSS_LDAP (Linux), and LDAP-UX (HP-UX), and relied on tools that were supported by the OS vendor, avoiding the use of costly third-party software and streamlining support. Nearly a thousand user accounts were migrated, access control was tightened, and hundreds of unneeded accounts were removed.
RHN Satellite. As part of an effort to streamline patching and new server deployments, I deployed Red Hat's server management system, RHN Satellite. Using Satellite, I created custom server build scripts that allow new systems to be deployed in as little as five minutes, a dramatic improvement over a process that usually took a full day. Custom configuration was included, including deployment during server build of important third party applications and utilities such as VMware Tools, NetBackup, ProLiant Support Pack, etc are now able to be automatically deployed. This infrastructure also allows for rapid patching and rollbacks, enabling H&R Block to patch all of its Linux systems in a week or two (depending on production availability), compared to the three months it took previously.
Organizational improvements. While there, I made several important organizational improvements. First of all, I reorganized and expanded their server documentation, making note of important information such as domain, network location, and server status. I also inventoried their support levels and identified many development and test systems that improperly had 24/7 support, which will save H&R Block thousands of dollars over time. Finally, I did a support budget analysis for fiscal year 2011 through 2013, recommending that H&R Block consolidate its support dates so as to save approximately $26,000 up front and make its support renewal process much easier in the long run.
May 1998 - Mar 2009
Systems Administrator III for Sprint Nextel.
I was the lead administrator of two clusters of SGI Origin servers responsible
for the collection and processing of $35 million in billing per day from
Sprint's Nortel DMS long distance telephone switch network. My
responsibilities included resolving hardware, operating system, and application
issues, coordinating developers, managing vendors, and
working with customers to exceed the company's goal of 99.99% availability.
In addition, I was the secondary administrator for three Sun Enterprise clusters
collecting Sprint's ATM and Frame Relay billing as well as a large, real-time
fraud detection and prevention platform consisting of twenty-four diverse Sun
Solaris systems. I also provided key technical leadership for many business
critical projects ranging from application updates to entire system redesigns
in support of new product releases. For example, due to my lengthy experience
with Linux, I was selected to serve on Sprint's Linux Evaluation Team
that set standards and made vendor recommendations for Sprint's ongoing
strategic rollout of Linux into the enterprise.
I was formally recognized seven times during my time with Sprint. In 1999 I received three Sprint Values Excellence awards for my work in upgrading a critical platform and for moving several applications from non-Y2K-compliant systems onto supported systems. I received another in 2000 for my efforts supporting the deployment of a new Nortel DMS long distance switch in record time. I also received an award for my success in recovering several million dollars worth of lost billing information in 2001. Later that year, I was awarded a Sprint Annual Award for my successful efforts to prevent a troubled switch deployment from failing, helping prepare the company to meet increasing customer demand. In 2007 I received a merit award for continued, superior performance and customer focus.
Mar 1997 - May 1998
System Administrator for Internet Direct Communications.
Responsibilities included maintaining a dozen Linux and BSD/OS servers that
provided infrastructure and customer services including email, DNS,
Usenet News, and webhosting for this regional Internet Service
Provider. I also provided support for several Cisco, Ascend, and Bay Networks
Internet routers. I maintained positive relationships with vendors and
clients and supervised the technical support department consisting of six
direct reports. In addition, I developed, deployed, and supported a web-based
accounting and administration system (using PHP, PostgreSQL, and Apache),
streamlining business operations through the automation of complex billing and
administrative functions.
Completed four years of coursework towards a degree in Computer Science. Courses included: Discrete Structures, Computer Systems and Assembly Language, Data Structures and Algorithm Analysis, Computer Architecture and Networks, and Introduction to Automata Theory.
Sep 1996 - Present
Founder of KULUA, the Kansas Unix & Linux Users Association, a large Linux
and BSD users group based in Lawrence, which brings together over 350
professionals and enthusiasts from the Lawrence, Topeka, and Kansas City
areas.
Mar 2009 - Present
