Systems Administration

Multiple systems administration roles have allowed me to confidently manage & monitor large networks of varying architectures, platforms, & network technologies.  Some of the key areas I have had worked with are:

  • All Mac workplaces, with offsite iPad, iPhone, and Macbook management.
  • Computer labs – 600+ devices ranging from fixed desktops with domain logons, to tablets & laptops. System imaging & Ghost was heavily used along with image creation.
  • SANs – Dedicated hardware appliances with multple drives, linux servers with raid, FreeNAS
  • Servers – Virtualisation (KVM & VirtualBox), Windows server with active directory, Linux servers of varying distributions, OSX Server, Web servers (AWS). High availability clusters with Galera & GlusterFS.
  • Backups – Automated backup shell scripts, rotating failsafe storage methods, complex rsync scripts using comparisons to use minimal bandwidth.
  • Dumb terminals – Linux thin clients connecting to a Windows Terminal Server
  • Data migration – Website transfers, mysql databases, storage upgrades, amalgamation of servers.

Signchro

Cloud connected digital content distribution platform for digital signage, digital menu boards, & custom developed information panels (apps).  All developed with a few primary goals:

  • Bring amazing features to the client that previously required custom development for each scenario.
  • Synchronise real-time content across multiple players & sites automatically – with no technical knowledge needed.
  • Make it easier for everyone by reducing complexity that plagues other systems, resulting in much lower costs to the client & the business

Signchro consists of 3 primary components – Media Player, Cloud CMS (signchro.net), Remote Control – which are detailed below:

Media Player
Compact yet powerful embedded system based around the Intel NUC, running a highly customised version of Slackware Linux 64bit.  The player is completely autonomous and is configured via the signchro.net cloud CMS.  It is an object oriented digital media system meaning components can be placed anywhere on the screen – not restricted like zone or template based systems.  Multiple channels can be loaded so it can act just like a regular tv service.  The primary technologies used are Dojo, JSON, Javascript, AJAX, & PHP.

Remote Control
Mobile & Tablet optimised application allowing the client to control various aspects of their associated Media Players.  Some of these activities are editing menu items, drawing members badge draws across multiple sites simultaneously, & switching the currently running channels.  Primary technologies used are Dojo, JSON, Javascript, AJAX.

Cloud CMS (signchro.net)
Content creation & player management interface for the client to create their own shows.  Based around the WYSIWYG idea, clients can drag components to where they require within their displays.  A built in content library allows for rapid content creation with very little training or graphic knowledge.  Hosted on a server cluster powered by MariaDB Galera & GlusterFS.
