- Grew a fashion rental and resale marketplace to 30+ curators and thousands of rentals in eight months, after surveying 30+ potential renters whose answers led to launching without a subscription.
- Built an internal AI photo studio that renders catalog images in a 47-second median: 89% approved on the first render, 0 rollbacks on live-store updates.
