Jamie has been in love with games for their entire life, and has been designing games almost as long. It started as a creative outlet and a way for their autistic brain to make sense of the world when they were growing up, but their desire to design games for others to play has been a constant in their life. They designed their first hobby games to show to others in 2013, and never stopped. 

In 2018, they transitioned from a hobby designer to a professional one when they joined the Boston chapter of the Game Maker's Guild. There, they honed their design skills through playtesting countless other games while constantly experimenting with and iterating on their own, learning what it takes to make a successful game and bring it to market. Jamie established their game design studio Triple Rainbow Games in 2020, in anticipation of self-publishing their game Fight Sequence.

Their development in the world of board games didn't stop there - since then, they've been an active member and playtester of many board game Discord servers, became a moderator and event host for Break My Game, and is now one of the co-hosts of the board game documentary podcast Building the Game.

Jamie lives and breathes board games, and their talent and experience as a playtester shows in every session.

Professional Playtesting and Game Development

As a playtester, developer, and designer, Jamie's expertise is in strategy games of all kinds, especially:

  • Strategy card games of any type

  • Two-player games, or 2P modes of larger games

  • Eurogames

  • Worker placement mechanics

  • Resource management/action economy mechanics

  • Area control mechanics

  • Any sort of combat/yomi mechanic

They have an affinity for a wide spectrum of strategy games, from two-player games with lots of interactivity to longer engine-builder euros where your primary opponent is the game system itself.

Diversity and Sensitivity Consulting

As a queer, autistic, nonbinary person themselves, Jamie has the lived experience of what it feels like to be othered, wondering if the people they interact with even know how to respect and understand them. That experience has guided them in their mission to ensure as many people from as many different backgrounds and walks of life as possible feel welcome and celebrated at the table.

Jamie firmly believes that diverse, mindful representation makes games - and the industry as a whole - better for everyone, and would love to use their knowledge and experience of underrepresented demographics and tackling sensitive subjects to help other designers create a more welcoming space for all!

Rules and Layout/UI Editing

It's no secret that in order to succeed as an independent designer, you need to wear many hats.


Jamie has developed a robust skillset they can utilize to help you make every aspect of your game that players interact with better - from technical and conversational rules editing to in-depth layout and UI testing that saves graphic designers hundreds of hours of work and energy on the final product.
