Inspiring hearts, one pixel at a time. ----

My name is Raynard Christian. I am a game programmer, designer, and systems engineer that is dedicated to building engaging gameplay. From architecting complex physics systems to refining AI behaviors, I believe that the best player experiences are built on a foundation of elegant code.

With a Bachelor's degree in Computer Science and an emphasis in Entertainment Arts and Engineering as well as a Master’s degree in Game Engineering from the University of Utah, I’ve spent my career crafting unique worlds with game development. I’ve helped bring projects like Trash Pandamonium, Doug Out, Pony Express, Operation P.L.U.S.H., and HorseHair to life with a deep focus on systems and gameplay programming.

I am currently employed in 3 Squared Cubed as a Games and Systems Engineer, while also exploring new ways to push the boundaries of genres and platforms. Focusing on Unreal Engine and Unity development and researching on VR/AR implementation, I love the challenge of a fresh project and the collaborative energy of a team striving to create something impactful.

Recent Project:

HorseHair (2026)

The game is waiting. The horse is grinning. The house is getting dark. Horsehair is a short point and click horror experience about retro fighting games and uncomfortable familial tensions.

Contribution:

  1. Developed a custom Point and Click system with a fully designer friendly Camera Navigation tool to tailor the atmosphere.

  2. Worked closely with Lead Designer in bugfixing and crafting systems for interactables and cutscenes in order to bring to life the horror theme.

  3. Helped maintain game design document in order to keep track of design goals and objectives to maintain steady workflow.

Platforms: Steam / PC
