Trueque
A mobile buying-and-selling experience that uses reusable patterns to make discovery, listings, profiles, and messages feel connected.
01 · Overview
Marketplace products contain many repeated actions and states. Without a shared system, familiar tasks can feel inconsistent and less trustworthy.
The project explored the core experience and the components needed to support it. I treated the design system as part of the product logic, not as a separate presentation layer.

02 · Process
A clear structure from question to design direction.
Identified repeated interface patterns and converted them into reusable components.
Documented variations and states so cards, actions, and messages used one visual language.
03 · Design decisions
The thinking behind the work.
Trust in context
Seller and listing information stay close to the action so buyers can decide with confidence.
Reusable patterns
Shared components reduce inconsistency across feeds, profiles, and conversations.
Clear next actions
Each screen emphasizes one primary action while keeping supporting choices available.
04 · Outcome + reflection
Outcome
The concept demonstrates how a small component set can support several connected marketplace tasks while preserving a consistent experience.
What I learned
The system was most useful when it clarified behavior as well as appearance. A good component defines what changes, what stays stable, and why.
