Overview
Biography	Born 2 October, 1978, in Carnarvon on the Gascoyne River. Citizen of Australia by birth and Éire by descent. Studied as a big-iron Unix programmer and very applied mathematician at Griffith University in Brisbane, pursued a mixture of further study and contract programming in an arc from Brisbane to Darwin, many years as a migratory research software engineer and odd-jobs man around the University of Queensland, this year a software developer at the data end of the ARDC. Wants to be independently wealthy and free to hack on interesting problems. Plays far too much go, reads speculative fiction in industrial quantities, tests out as a Jung-Meyer-Briggs INTJ, is a practicing Roman Catholic.
Programming	Speaks eloquent Python and PHP, fluent Javascript, SQL, bash, rusty C, Go, Rust, Java, Haskell, VBA, FORTRAN 95 and Matlab, pidgin FORTRAN 77, Prolog, C++, Perl 5, TeX. Prefers Haskell or Python but will code in anything. Mostly command-line or browser interface, has built GUIs at need. Has used the standard Python, PHP, and C bindings for MySQL, MongoDB, and SQLite to write applications and scripts, can write raw queries to taste. Knows how and why to use source revision control (cvs, svn and git) respository interfaces (Bitbucket, Github, Gitea), issue tracking (Trac, Bitbucket and RT) and documentation wikis (MediaWiki, Trac, Confluence). Can reason about and implement various forms of distributed computation, from threads through cooperating processes to MIMD in-cluster parallel processing to WAN-scale clouds. Classically trained computer scientist, which means the reasoning about correctness and consistency and performance will be correct. Skills in respect of numerical methods on all of the above are rusty but present. Can run the entire SDLC from scoping through requirements elicitation, design, implementation, testing, integration, deployment, and maintenance, collaboratively or autonomously. Initially trained on the PMBOK but have since learnt to be iterative, agile, secure, distributed, and all permutations thereof. Largest development team to date, three. Has mapped and analysed spatial data with ArcGIS, especially the Spatial Analyst toolbox and scripting with the Python API, and processed satellite and aerial imagery with ENVI. Writes fluent HTML and CSS. Has built web applications out of Python (CherryPy and Flask), PHP (raw, as Wordpress plugins, as Drupal modules, or as CodeIgniter\|Symfony models/views/controllers), Javascript (client-side JQuery), Java (applets and servlets), and occasionally Perl. Can maintain and build Drupal sites from the administrative web interface and on the command line using drush, generating nodes dynamically using the Drupal API in cron and drush scripts, write and maintain custom modules. Can build dynamic web sites out of Wordpress; install, configure, customise, maintain and debug plugins and themes and bbPress forums for same.
Systems	Familiar with the Unix command line; can get work done in most POSIX-compliant environments. Has built and maintained servers and workstations out of multiple dialects of Unix (including RHEL, CentOS, Arch Linux, Ubuntu Linux, Solaris and OS X). Can install and administer HTTPS, SMTP, and NTP daemons to taste. Can configure routing, ARP, DHCP and DNS for middle-sized networks; speaks enough IOS to wrangle Cisco routers, can build network appliances (firewalls, routers, NAT and VPN endpoints) out of Linux, Ethernet cards, stringybark and greenhide. 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. Has been a tier 1 Active Directory and Exchange administrator, holding delegation to manage email and AD profiles for users of a university organisational unit, back when that was a thing. Has developed against the LDAP interfaces of same for authentication, group membership and authorisation at UQ.
Other Skills	Has used honours-level applied mathematics and statistics to solve problems and answer questions, by hand and with Matlab, NumPy, C, R, Mathematica, FORTRAN. Holds a current Queensland class C license (manual and automatic under 4.5t). Knows when and how to provide first aid, holds current St John's certification. Speaks the Brisbane dialect of Auslan as a second language. Plays go at single digit kyu strength and can teach double-digit kyu players. Can teach and assess small groups; has taught Java, C, Python, discrete and continuous mathematics as lecturer, guest lecturer, demonstrator and tutor to Australian undergraduates, has run random introduction-to-this-software-or-service sessions with too many users to list. Largest teaching team led to date, two tutors and two markers. 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. Has created and hacked on presentations, spreadsheets, correspondence and other documents with Microsoft Office, LibreOffice, TeX, iWork, Inkscape, Dreamweaver and Acrobat.
