Designing human-centered systems for complex, high-stakes environments.

The cost of an unclear error state is paid every shift, every station, every operator. I scope exception handling with happy-path UI.

Operators can only act on what they can see. If the system doesn't surface state, they invent their own.

Decisions made under fatigue, noise, and rate pressure are the ones that fail. I design the interface to absorb that load instead of adding to it.

When a fleet scales an order of magnitude, the human-readable signal has to scale with it — or response times balloon and the system stops being collaborative.

Fixed hardware, legacy architecture, aggressive launch dates — these aren't excuses, they're the design brief. The most resilient solutions live inside the constraint.
