I work with game teams on the stuff that actually matters, shipping on time, making the most of what you've got, and keeping the creative spark alive when deadlines are breathing down your neck. I've been in the trenches with studios trying to scale production and indie creators scrappily proving out ideas, and I've learned that the best solutions aren't fancy, they're just clear and playable. I show up as someone who listens, collaborates, and keeps players first, because that's where the work actually gets grounded. And yeah, I'm Jack Donavan
