Onboarding took days. After the rebuild — 2 minutes, no dev required.

The client asked for a redesign. The real problem was 16 disconnected steps for one routine task.

Aquaculture data entry — 16 steps down to 4. Same backend rules. Completely different experience.

These case studies reflect my approach to clarity, usability, and design systems. Each project pairs research with shippable interfaces.
