Contract Work

Sparx Ltd

Alistair has worked as a contractor for Sparx Ltd, an educational software company in Exeter, since 2013. Sparx develops a Mathematics-learning software solution for use in the classroom, independent learning and homework.

Working for Sparx, Alistair has designed and created times-tables learning games that algorithmically respond to student ability, and deliver learning goals. The games also provide data to the statistical research team at Sparx, to optimise its performance as a learning tool.

The first generation of Sparx games were developed in Objective-C as apps for iPad. The current generation of Sparx games are developed in Javascript/HTML5 and are integrated into a web-app platform.

The games communicate with server-side code written by Alistair in Python and Google Cloud code written in Go.

In addition to writing the games, Alistair has created game-creation frameworks for use internally within Sparx. These unify common UI elements, user interaction, animation, quiz integration, and network communication, to make all of the above accessible for new developers seeking to make games for Sparx's platforms.


In 2014 Alistair developed a web game for the BBC as part of an unreleased BBC product.

The project brief was to take an abandoned prototype by another production team and develop it into a fun and fully featured game that met the Coporation's user-experience and accessibility standards.

The game was developed in Unity for the Unity Web Player.

Alistair's updated design for the project added in meaningful player decisions, room for strategy and experimentation, and social competition.

Alistair also integrated the BBC's bespoke networking features into the project, and optimised load times and performance for use in the browser.

Development Profile

Alistair has developed critically-acclaimed games from conception to commercial release entirely as a one-man team.

Through this process he has developed the ability to solve problems independently, and to deal with the challenges of creating stable complete software for a real-world marketplace.

In addition, this process has required him to fearlessly take on all responsibilities of the development cycle. He will proactively learn new skills and pioneer new techniques to achieve his goals. This includes business and promotion skills as well as technical skills.

Throughout the development process Alistair is a great believer in live user-experience feedback. During his projects he frequently draws upon user test sessions to understand the state of the product from an end-user's perspective.

Working at Sparx Ltd has required Alistair to work productively as part of a larger team. During his work for the company he has needed to design games capable of meeting the needs of teachers and students, as well as the broader goals of the company.

In developing the shared games framework used by the company, Alistair has focused his attention on extensible, well-organised and readable code. This allows more developers in the team to work on game projects. The focus of his attention has been on minimising the amount of prior knowledge required to create a Sparx game. He has also strived to make the existing games useful references that future developers can use for guidance.

Throughout these projects Alistair has demonstrated ability to deal with networking issues, performance optimisation, threading issues, user interface design and memory management. He also designed and implemented the algorithm for teaching times tables in both Lua and JavaScript.
