• See sections below for skills (programming, system administration and operations, other), employment (quarter century as a full stack Unix programmer analyst), education (baccalaureate with honours), publications (for completeness), affiliations and service (for background).
• Biography: studied as a 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. Born 2 October, 1978, in Carnarvon on the Gascoyne River, citizen of Australia by birth and Éire by descent. Plays far too much go, reads speculative fiction in industrial quantities, tests out as a Jung-Meyer-Briggs INTJ, is a practicing Roman Catholic, qualified for Australian Mensa by standardised testing at the 99th percentile in June 2003, but mostly it doesn't show. Wants to be free to hack on interesting mathematically-solvable problems and code useful software, and also, have more time to read.

Skills

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 desktop GUIs when required. Recruiters who are looking for years of experience: the only programming listed in this document that shouldn't have "twenty years of experience in" are the ones where the technology or language or library isn't that old, in which case you can safely assume I picked it up within a year of it being invented, because I predate it.
• 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) repository interfaces (Bitbucket, Github, Gitea), issue tracking (Jira, 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.
• 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, servlets, raw Tomcat and Springboot), and occasionally Perl. Familiar with Drupal and Wordpress and has built and maintained sites in both.

Functional understanding of other interconnects (Infiniband using OFED, IPoIB, other RDMA implementations) and how to cable them up and diagnose and fix problems.
• Can administer and tune MySQL and PostgreSQL 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 Linux and Unix hosts on bare metal and in virtualization, mostly Openstack for production NeCTAR, and KVM, Virtualbox and VMWare ESX for other projects.
• Has been a junior operator on a national-scale federated OpenStack cloud, as part of a local team and in coordination with other teams at other geographical nodes. This includes racking and cabling the hardware in the data centre, building, patching, monitoring and maintaining the hosts, per-host and per-undercloud services, operations on Ceph and hierarchical storage layers, and liaison with vendors for technician attendance, replacement parts, software bugs and emergency response. No, nobody likes attending the data centre at ten in the evening or chasing down the storage bug from log entries. Yes, I can and will do it.
• Can make and use container images from software with docker(-compose) and podman(-compose) and run them on Ubuntu, RHEL and Rocky Linux, and configure networking and security within and across container hosts.
• 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.
