Creator of Rival Megagun

I'm Justin. I like to create all kinds of things. Especially video games.

In 2013 I completed my diploma in Computer Systems Technology in Victoria, BC, Canada and went on to work at a local video game studio for three years. Following that, I took the leap to finish my passion project: Rival Megagun.

I worked for two years full-time on Rival Megagun, a classic bullet hell ‘shmup’ with a focus on competitive multiplayer. Japanese publisher Degica picked it up in 2017. I traveled around the world showcasing Rival Megagun at conventions including PAX South in San Antonio, TX, and BitSummit in Kyoto, Japan.

Rival Megagun was released worldwide on PC, PS4, Xbox One, and Nintendo Switch on November 29th, 2018. Here are some reviews.

My skills include:

  • Game design and development
  • C#, Java, C++, HTML, CSS, JavaScript
  • Unity, Unreal
  • Nintendo Switch, PS4, Xbox One, iOS, Android, Steam
  • Real-time online multiplayer with Steam, Nintendo Switch, PS4, Xbox One
  • Platform-specific features and services such as achievements, leaderboards, save data
  • Platform certification (Nintendo Lotcheck, Sony TRC, Microsoft Cert/XR)
  • Rapid/throwaway prototyping
