  • Can administer and tune MySQL on the Unix command line, MongoDB on Unix via Javascript and Python command lines, sqlite3 on Unix via shell and Python command lines.
  • Has built hosts on bare metal and in virtualization, mostly Openstack Pike through Xena for production NeCTAR, and KVM, Virtualbox and VMWare ESX for other projects.
  • Has done first-tier, second-tier and third-tier software and hardware support for users presenting in person at a helpdesk, over the phone to a formal support line, and by email. Groks the concept of appropriate escalation and the limits of SOEs and SLAs. Experienced with the Freshdesk, Zendesk, Oracle Service Cloud and Request Tracker ticket platforms.
  • Has built small Windows servers (NT, 2003, 2008, 2012) and workstations (XP, 7, 8, 10, 11). Adequate WSL and cygwin-fu.

  • Can engage with the scholarly literature (has reviewed for several CS conferences, and the IEEE magazine Distributed Systems Online), writes a mean literature review and has first or second authorship of some conference papers.
  • Can do the clerical work of an Australian university research group (proofreading, filing, shelving, stores, OH&S as a trained WHSR and fire warden, mail, data entry, sample curation, logistics), collaboratively or autonomously.
  • Can run small voluntary associations (organise events and tournaments and the catering and venues thereof, run and constructively participate in committee and general meetings, keep correct records and report from them, write and debug group constitutions, write budgets and disburse or procure according to them, handle petty cash and banking, recruit and manage volunteers, build and maintain group social media) collaboratively or autonomously.
