David McCullough
designer, systems thinker, dad
Product design at the boundary of strategy and engineering.
I turn ambiguous direction into durable, coherent product systems—so teams can move fast, make the right tradeoffs, and ship work that holds up over time.

Selected projects
Self-service / Admin (SaaS + PLG)
Designing scalable self-serve configuration and workflow management.
Cross-platform design system
Patterns and components that keep multi-surface products coherent.
In-store fulfillment (pick/pack)
Operational workflows optimized for speed, accuracy, and edge cases.
