TIMELINE
2022.04 - 2022.06
Business Goal
Through this iteration, we aim to improve user browsing efficiency, enhance conversion through high-quality content, and ultimately increase business profits
Methodology
Process mapping helps us quickly understand how things work before jumping into design.
As we move through the design process, we use it to break down key challenges into specific problems, spark new ideas, and shape practical solutions.
Define the Problem
Everyone needs a car. But finding the right one? That’s a journey.
To discover opportunities I utilized 3 research methods to dive deep into the problem

Surveys

Observations
Research
USER INTERVIEW AND PRODUCT NEED
We sat down with real users—not just to hear their thoughts, but to understand their world. Through these conversations, we uncovered how they search, what they hesitate over, and what gives them confidence when making choices.
KEY INSIGHT FROM BUYERS
Insight 1
Price Is King
Users care most about finding a good deal — price over features.
Insight 2
Thorough researchers
They dig deep into details like mileage, condition, and warranties.
Insight 3
Mobile-savvy
They expect a smooth, app-friendly experience on their phones.
DATA-DRIVEN DESIGN: SHAPING THE USER EXPERIENCE
Visual Direction
Based on user demographics and behavior, we recommend a youthful, clean, and efficient visual style for the used car app—prioritizing clarity and ease of use across mobile devices.
HANDS-ON TESTING: LEARNING DIRECTLY FROM OUR USER
To truly understand what our users need, we didn’t just rely on interviews—we invited them in. By watching how real people interact with the product, we uncovered issues we wouldn’t have found otherwise and sparked ideas we hadn’t considered.
🧠 One moment stood out:
Several users couldn’t find where to start the car purchase journey on the homepage. It wasn’t obvious—and it slowed them down.
So, we made a call. We redesigned the homepage layout to make the entrance more intuitive. Now, users can land, explore, and take action with less effort—no guessing required.

Current Homepage
Current Listpage
Several users couldn’t find where to start the car purchase journey on the homepage. It wasn’t obvious—and it slowed them down.
Visual Overload Hurts Credibility.
Interaction flows are complex and overloaded with unnecessary steps—like horizontal swiping—that don’t align with users’ typical mobile behavior. This contradicts the product’s goal of being simple and efficient.
Essential content—like how to start the car-buying journey—is buried or unclear. This disconnect between user needs and interface clarity leads to confusion and lowers satisfaction.
Brainstorming
To break down user pain points, I partnered with the product manager in a series of mapping sessions.
🧩 Reorganizing the Homepage
After analyzing the existing layout, we restructured the homepage with a focus on user priorities:
Added entry points for buying and selling cars
Introduced brand stories and buying guidance
Highlighted key features and smart recommendations
This modular redesign made it easier for users to find what they need without friction.
Design
WIREFRAME & INFORMATION STRUCTURE
Before jumping into high-fidelity design, we sketched out early concepts based on user needs and real-life scenarios. These quick drafts became a powerful tool for aligning with stakeholders, speeding up discussions, and laying the groundwork for fast, confident decision-making.

USABILITY TEST
Before launching the new version, we ran remote usability tests to observe how users interact with set tasks and identify any friction points in the experience.
🔍 Test Summary
All participants successfully located the car buying function and completed the process in under 2 minutes. This validated that the new entrance and flow are intuitive, efficient, and ready for development.
DESIGN SYSTEM
I manage design files and maintain reusable components to ensure consistency and improve efficiency across design and development teams.
The Impact
After 2 months of launch, the new version exceeded performance expectations, showing significant improvement across key metrics.
