Founder & Director, One Day Games. 18 years across Treyarch, Deviation Games, and Sony Interactive Entertainment.
CJ spent 11 years at Treyarch on Call of Duty: Black Ops 1 through 4 as the point Zombies producer on BO3 and BO4. shipped Der Eisendrache, Mob of the Dead, Shadows of Evil, Voyage of Despair, Gorod Krovi. authored the Production Playbook that scaled with the franchise.
from there, CJ was founding producer at Deviation Games, the PlayStation-backed studio. four years building original AAA narrative IP from zero; studio formation through active production, and standing up the XDev function alongside it. most recently creative lead on a new first-person co-op AAA IP at Sony's Dark Outlaw Games, with three months on-site in Prague directing a 60-person co-development team.
One Day Games is what CJ is doing now. solo studio, AI-native, building faithful digital companions for tabletop IP. the work is a translation problem more than a porting one; taking a finished physical game and authoring its digital companion without losing what made the original feel like itself.

Trash Dice
in development
Digital companion for a popular retail tabletop dice game. Currently exploring platform-licensing structure with the publisher.
The autonomous pipeline
The studio runs on an AI-augmented pipeline that releases, monitors, and patches itself with zero daily ops input. Documented self-recovery from a bad deploy in April 2026.
The thinking
the closest analog to what One Day Games does is what McFarlane Toys does for physical IP: a named interpretive studio whose hand adds value, not a service house executing on someone else's spec. tabletop IP holders shouldn't have to give One Day Games notes on whether the digital companion feels right, the same way they don't tell McFarlane how to sculpt the figure. that posture changes everything about how the work gets structured: what gets reviewed when, who decides what's faithful, what the pipeline IP carveout looks like.
