PROBLEM

A powerful flagship tool that users couldn't figure out

ExperienceEngine let merchants add free gifts and discounts to Shopify subscriptions based on conditions, but merchants consistently found it confusing and hard to use.


Adoption sat around 10% despite it being our flagship product, and CX research showed the interface gave users no sense of where to start or how the pieces fit together.

RESEARCH

Interviews to validate a clearer, step-based redesign

Working from feedback already gathered by CX, I redesigned the experience and interviewed merchants across several tiers to react to it.


Response was strongly positive. Merchants called it clear and organized, and several said it felt like steps, where before they didn't know where to start. Feedback shaped a few labeling and icon tweaks, but the core strategy held.

TESTING

AI prototyping for a more realistic testing scenario

Instead of a hotspot prototype, I used Figma Make to turn designs into a functional, data-persistent React app in one morning, work that would normally take weeks.


Testers entered real data and watched it save, so sessions tested actual logic and micro-interactions instead of a simulation's limits, shifting testing from explaining a concept to testing a reality.

RESULTS

Every adoption metric improved, with no new features.

Traffic to Promotions page and new promotion attempts roughly doubled in just six months.


Task completion rate rose 11%, which combined

with the traffic increase to raise overall conversion by 140%. Analytics opens grew 130%, with 86% more unique users checking results. All from front-end usability changes alone, no new features added.
