David McCullough

I'm a designer with a non-linear background in both design and engineering. That combination has shaped how I work. I care as much about craft and interaction design as I do systems and product outcomes.

I do my best work in complex environments - the kind that require systems thinking, cross-functional collaboration, and clear product judgment. I like untangling ambiguity, highlighting tradeoffs, and helping teams shape ideas into something coherent, useful, and well made.

Much of my career has been defined by long-term ownership: working across connected surfaces, helping products mature over time, and building foundations that support future growth.

Outside of work, I'm drawn to things with character and longevity: old houses, rare books, antique furniture, passion-project indie games. I'm based in Tucson, Arizona, where I live with my family and our dog, Moose .
