Second-life App — Rethinking E-Waste, One Pickup at a Time
A solo UX case study tackling e-waste through a scalable mobile platform. Designed in React Native, it lets users schedule pickups, shop refurbished tech, or become carriers—bridging sustainability and convenience through a multi-role experience. (Duration: 2022-2025)
Project Overview
UX Research & Strategy
Understanding user needs to shape meaningful, value-driven solutions.
Through in-depth surveys, interviews, and competitive analysis, we uncovered several critical insights that directly shaped the Second-life App’s value proposition. These findings moved beyond initial assumptions and highlighted user motivations rooted in security, trust, convenience, and environmental impact.

Iterated from 5 paper wireframes to finalize Version E
​
Started with five home page versions in the "Paper wireframe" stage, then advanced Versions B and E based on usability test results (👉 Check Usability Testing Report). After further A/B testing and iteration, Version E was finalized as the high-fidelity mockup (👉 Check A/B Testing Report).
→
↑ Version B:
-
Clear step-by-step structure
-
Large, accessible buttons
-
Linear flow caused friction
-
Delayed address input frustrated users
(Wireframe)
→
↑ Version E:
-
30% faster task completion
-
Intuitive location-first design
-
Bottom navigation improved orientation
-
Better user autonomy and efficiency
