    I'm an adept programmer and love learning

    I love coding and game development with a passion, and solving challenging problems by working with others to hit deadlines. I realize that I don't know everything, but I recognize my weak points and add it to my learning.

     

    Over the years though I've honed my experience with the following:

    • Languages:
      C/C++, LUA, C#, Python, GSC.
    • Version Control Software: 
      Perforce, Git, Subversion.
    • Project Management Tools:
      JIRA, Trello, Hansoft.
    • Software:
      Visual Studio, Havok, InstaLOD, FMOD Studio
    • Engines:
      Unreal Engine 5 / 4 / 3 (Licencee Version) and other industry leading proprietary technologies.

    I'm a STEM diversity advocate and enjoy speaking and presenting

    I believe everyone should be able to make games and that having diverse people brings a plethora of benefits to not only the team but the project as well.

     

    To help with this, I've co-created a STEM scholarship to promote and inspire people from diverse backgrounds into games development and tech.

     

    I also regularly speak at conferences, conventions and to media and provide advice for students and buddying game developers on how they can start making their own games.

     

    Portfolio Reviews

    If you'd like a CV or portfolio review please send me an email! I love to pay it forward and I've helped over 50 buddying developers land their first game development role since 2019.

     

    Note 22/06/2024:

    Due to the influx of requests due to Video Games Industry Layoffs I have an extremely large backlog of these to get through. Please be patient as I get through them :)
