Network Time Foundation

• Linux Administrator

  • Dec 2011 - Present

  I volunteer my spare time to NTF. Working with NTF has taught me experience in working in a remote team environment. At NTF I apply my in-depth linux knowledge to solve problems brought to me. If the time on your computer is correct, it's probably because of Network Time. Network Time began in the earliest days of the Internet, and one could easily assert that it has been and remains one of the most critical core-components of the Internet. For too long, Network Time was cared for by a small group of dedicated and passionate volunteers. With the creation of Network Time Foundation there now exists a means for focused professional effort to be made for all aspects of Network Time. Show less

Pivit

• Linux System Administrator

  • Aug 2015 - Dec 2016

  I came into Pivit to redeploy their entire server infrastructure. The current servers Pivit ran were getting tired, so I had the perfect chance to redploy thier entire stack in a "greenfields" like scenario. I was requried to understand the current layout and come up with a buisness plan to move everything into the new stack. This included selling the idea to the CEO all the way to deployment. This gave me a great chance to expose myself to new skills and challenges. I have had the chance to expand my coding from Perl to Python, and have developed a few Python scripts at Pivit to make my life easier. So far I have implemented for Pivit: - 2x oVirt virtualization clusters compromising of 3x Dell R630 servers, 1x Dell SAN and 1x Dell 10GB switch - WWW cluster based on Nginx using GFS2, Pacemaker for the shared disk locking - HA MySQL stack based on MariaDB + ProxySQL - HA LDAP - Redis, ElasticSearch, Logstash, Kibana stack - Sympa Mailing List - Memcached cluster - MongoDB cluster - Docker Distribution - HA Radius - HA DHCP - LibreNMS - Katello+Foreman - Shinken + Thruk - IPAM - DNS - OpenGear OOB - Request Tracker - Python syncer script from libreNMS into Shinken Show less

World Smart Retech

• Level 2/3 GM Hardware Support Officer

  • May 2005 - Jul 2007

  My position at World Smart Retech was to solve hardware and software issues remotely over the phone to clients. This job was a challenging experience for me as you had to learn how to ask the correct questions to ascertain what the issue was and talk the client through fixing the issue over the phone. Sometimes I could fix issues by writing bat shell scripts to do the work for the client, like reboot a computer or search and clean up un-wanted files. I really enjoyed writing these scripts, as I enjoy the design aspect. I thoroughly enjoyed the feeling you got by helping someone who really needed the help and appreciated what you did for them in fixing the issue. Show less
