Linux Systems Administrator

Results-oriented Linux systems administrator with 18 years of proven experience managing heterogeneous networks. Background includes being the lead systems administration and InfoSec team lead for a software company. Before that, I administered a major university’s Linux cluster, where custom modifications were made to optimize load balancing, and reduce disk usage by 97%. I also have experience running a technology consultancy, which has improved my ability to see technology from a business’s perspective and be self-directed.

Professional Skills

Systems Administration

Linux systems administration is my strongest skill. I'm at home in Red Hat and Debian based distros. I'm also comfortable with FreeBSD, Solaris, and macOS. I'm strong on virtualization, including KVM, and common network services like Apache, BIND, Postfix, Dovecot, PureFTPd, NFS, OpenSSH, and OpenVPN. I have experience automating tasks with Puppet, Cobbler, and Kickstart.

Security

Experience includes system hardening, firewall, and IPS configuration, encrypting storage and communications, using secure coding practices, performing vulnerability assessments, working with management to create and update security policies, and training users.

High Availability Computing

I'm experienced with configuring high-availability services, including DRBD, pacemaker, various load balancers, HSRP, VRRP, and CARP. I'm also experienced with configuring monitoring and notification systems including Nagios, Xymon, and PagerDuty.

Networking

I'm a networking geek at heart. I'm familiar with Cisco router and switch configuration, abusing Linux routing tables in interesting ways, configuring VPNs, setting up Linux and pfSense firewalls, and using low levels tools like packet sniffers and netcat to troubleshoot issues. I'm also experienced with long-range wireless networking using both 802.11x and proprietary equipment and am a licensed amateur radio extra.

Development

Most of my development experience revolves around Ruby on Rails applications and automating systems administration tasks with Ruby and bash scripts. I'm also familiar with PHP, Perl, JavaScript, CSS and a little bit of C.

Database Administration

I'm experienced with using, administering and tuning PostgreSQL, MySQL, and SQLite (in that order of competency). This includes PostgreSQL and MySQL replication. I have limited experience with Microsoft SQL Server, Oracle, and Sybase.
