I created an internal prototype testing harness that automatically generates a navigable schema from a functional prototype, letting teams review every screen, state, and instance without guessing what exists or missing edge cases.
Teams can toggle between realistic empty states and pre-populated demo data, compare each prototype state side by side with production, and test the same experience across tablet and mobile views in tandem.
This turned the prototype into a shared review artifact, QA tool, engineering reference, and handoff system — helping designers, PMs, engineers, and stakeholders validate product direction faster with fewer blind spots.
