About David Carr

I'm an experienced software engineer with interests in gamification, computer graphics, simulations and user experiences. I have over a decade of experience doing frontend and full-stack development with diverse multidisciplinary teams, with proficiencies in C#, .NET, SQL Server, Azure DevOps, Java, HTML, jQuery and others. I back this up with my academic research background, holding a degree and doctorate in Computer Science majoring in Games Technology, and have published papers on game mechanics for teaching physics. All up, I bring a unique mix of skills to problems of user interactivity, service delivery and automation, to which I love to find creative and elegant software solutions.In my eleven years working at the Australian Electoral Commission (AEC), I contributed to the development and maintenance of a range of data-intensive applications that support the AEC's mission and the delivery of services to the Australian people, developing a passion for the democratic process and civic engagement along the way. Two prominent examples of projects I contributed to are the Online Enrolment Service (OES) and Online Postal Vote Application (OPVA), a pair of online forms built in .NET which allow Australian electors to complete transactions over the Internet (viewable at https://forms.aec.gov.au/). In 2019, I remediated a slow-performing email and SMS message queue in these applications, achieving a hundred-fold performance increase and resolving a bottleneck in the delivery messages to electors. I also led the OPVA Responsive Redesign and Accessibility project which updated and modernised the UI of that service. During these projects, I received praise for my documentation, technical advice, and interactions with the business areas. I also contributed instrumental work to GVRS+, a low-cost voter and election management tool, provided by AEC as part of the Australian Government's outreach to Pacific Island countries. My duties included updating the aging software product, supporting remote clients with their individual instances and implementing fixes and new feature requests, while also contributing to the design of a replacement application.Additionally, over the last six years I was an integral member of the IT command centre during election events, directly supporting event delivery through monitoring key systems, resolving issues, and culminating in the publishing of results on voting night.Outside of work I enjoy new experiences through the eyes of my children, building scale models, and repair and resurrecting outmoded electronics.

  • Australian Electoral Commission
    .Net Developer
    Australian Electoral Commission Aug 2023 - Dec 2023
    Canberra, Australian Capital Territory, Australia
    Continuing in the .NET Team; retitled position due to organisational restructure. This period coincided with the commencement of the GVRS Hybrid project (building a new voter and election management product for AEC's international partners), along with the AEC delivering the first Australian Federal Referendum in a quarter century.- Involvement in GVRS Hybrid, a greenfields software project to replace the aging GVRS+ (Generic Voter Registration System) provided by the AEC in international partnership to Electoral Management Bodies in the Pacific. This project takes lessons learned from the old desktop-based product to design a modern browser-based solution that is maintainable, flexible and scalable through local, networked and cloud-hosted deployments. My responsibility was on the initial revised database design in Microsoft SQL Server, and I also gained exposure to several of the latest technologies including .NET 8, Entity Framework and Blazor while performing code reviews for my colleagues. This project was also the first implementing mature Agile project management practices in the agency.- The above project commenced to a dual backdrop of the Fadden By-Election in full swing, and preparation for the 2023 Federal Referendum on an Indigenous Voice to Parliament. While I was not involved directly on Referendum night, I did reprise my scribe duty through verification test, and provided monitoring and support of election systems including Online Enrolment Service (OES) and Online Postal Vote Application (OPVA). This included delivering critical fixes to OPVA for wording errors and data issues raised by the product owner, as well as responding to and post-mortem of a critical failure in downstream email services.- As I was concluding with AEC, a key focus was reviewing and updating wiki documentation and backlogs in DevOps, to ensure my SME knowledge is recorded and reference material on projects and processes is complete with no gaps for those coming after me.

    Software Developer
    Australian Electoral Commission Jan 2014 - Aug 2017
    Canberra, Australian Capital Territory, Australia
    Commenced as a developer with the IT Solutions - Roll Functions section, maintaining the applications used for managing enrolment data. These included GENESIS (General Enrolment Information System, an internal-facing Java 2 EE and SQL Server application integrating with mainframe programs), OES (Online Enrolment Service, a public-facing webform built on C#, .NET Framework and SQL Server which integrates with GENESIS) and IRIS (internal-facing image repository built on C#, .NET Framework and SQL Server). Some achievements are:- Worked on the address geocode conversion project in GENESIS, to align our database of 10+ million enrollable addresses with new data standards from the ABS and mapping authorities. The solution automated matching and boundary checking, saving an estimated 60,000 hours effort to manually encode every address in Australia.- Contributed greatly to coding the 'address trickle feed' in GENESIS, which keeps updated address data synchronised with the mainframe.- Worked on redevelopment of the IRIS solution to extend management options and types of content that could be stored. I wrote the design document for the new Content Management administrator frontend, implemented the agreed design alongside another developer, and trained the business users.- During the 2016 Federal Election, I was tasked with automating a manual status transfer command provided by the GENESIS web interface, as a stopgap to address poor performance of a backend queue causing status messages to electors to be delayed many hours. I succeeeded in producing a novel tool implementing Selenium Webdriver in parallelised virtual users, that was wildly successful in keeping the queue clear.- Contributed to upgrading the GENESIS server platform from Apache JBoss 4.2 to 7, primarily research and converting the integrated JMS message queue implementation to ActiveMQ.- Frontend development and testing in OES for enrolled address search and validation feature.

  • Australian Electoral Commission
    Project Officer
    Australian Electoral Commission Oct 2012 - Dec 2013
    Canberra, Australian Capital Territory, Australia
    Accepted into the APSC Graduate Development Program and commenced at AEC as an IT specialist. I completed four placements in different work units across the agency, plus an election placement, while also undertaking training and project work with peers across different government departments to earn my Diploma of Government. 2013 was also a Federal Election year, and I received first-hand exposure of the work the AEC does to coordinate the national vote, Australia's largest peacetime logistics operation. Finally, this also coincided with the start of AEC's journey with cloud-hosted services.Top achievements during my graduate year:- Involved (from the software development side) with the creation of 'IRIS', an in-house repository solution for the AEC's 50M+ enrolment document images. The specialist-designed solution is built on a SQL database, with C# and Powershell programs, optimised for large-scale storage and retrieval of relational content. The successful delivery of this project removed a key risk to the AEC's operations after the previous outsourced service provider had gone into administration in 2012.- Contributed to feature development in the backend management portal of the Online Enrolment Service (OES), a (new as of 2012) webform application built on .NET and SQL Server that enables members of the public to submit changes to their enrolment to the AEC via the Internet.- Involved (from the product owner side) with defining the business requirements for a new 'online signature' feature for OES. The delivery of this feature was an imperative before the 2013 Federal Election, due to the prospect of legal challenges if the AEC did not provide a sanctioned means for members of the public to submit a new enrolment online.- Directly assisting the ACT Australian Electoral Officer (AEO) through the 2013 federal election, with tasks such as verification of election materials (e.g. candidate lists), and overseeing data entry and scrutiny of ACT Senate votes.

  • Renaissance Games Online
    Frontend Web Developer
    Renaissance Games Online Jan 2007 - Mar 2009
    Gaston County, North Carolina, United States
    In the late 1990s and through the early 2000s, I was big into Microsoft's "Monster Truck Madness 2" (MTM2) PC racing game and the friendly online community creating custom tracks and vehicles (what would now be termed "modding") and playing in competitive multiplayer racing. In 2006, Microsoft closed their "Internet Gaming Zone" (the Zone) which provided chat and multiplayer lobbies for the game, leaving us without a gathering place for our online gaming. Community members approached providers of other online games services to host our game, and secured support with the newly emerging "Renaissance Games Online" (RGO) company. I programmed a custom lobby client to work with RGO's servers, allowing players to set up chat lobbies and launch peer-to-peer multiplayer sessions of MTM2, loosely recreating the Zone experience. This worked well and was well received by players in our community, with many remarking it was "just like the old days on the Zone". Unfortunately, internal politics and interpersonal drama within RGO eventually saw support ended, and the MTM2 community migrated to other less mercurial services for online play. (Gratis work)

    Caged Developer Jan 2003 - Jul 2004
    Bathurst, New South Wales, Australia
    In collaboration with another student in my undergraduate course, we co-developed and delivered a spelling game program we named "MagicSpell". The game was developed for Inala Special School, an educational facility for neurodiverse children in Brisbane, to replace a spelling game running on obsolescent Apple II-e hardware that the school relied upon. The gameplay loop consisted of a spelling quiz, the word list for which was configurable by the teachers, and a Space Invaders-style minigame as a reward. The game was well-received by teachers and students and fulfilled a need of the school for several years. (Gratis work)
