Project Details
Role: Lead Product Designer & Founding Designer (Solo UX/UI)
Scope: End-to-End Product Design, UX Research, Mobile App UI (iOS/Android),
Key Outcome: Transformed a fragmented prototype into a guided multi-step host wizard and a seamless guest checkout, eliminating critical task drop-offs.
Context
Upcar is a mobile-first car rental platform that connects guests with trusted local car owners.
The challenge was not just to make the platform look premium, but to solve critical usability failures in host listing and guest booking flows that directly impacted inventory, bookings, and revenue.
The Problem
The main issue facing the platform was fragmentation.
Host Friction: Hosts struggled to list their cars because the listing flow felt long, unclear, and broken across too many steps.
Guest Friction: Guests experienced a confusing booking process where pricing, delivery details, and next actions were hidden or unclear.
Drop-offs: Users frequently lost progress during their journey, damaging platform trust.
Marketplace Risk: If hosts cannot list efficiently and guests cannot book confidently, marketplace liquidity stalls and growth stops.
Research &
Strategic Decisions
By analyzing user journey drop-offs, observing user behavior, and mapping friction points, the key insight emerged: The issue wasn't a lack of features, but a lack of clarity.
Design Decisions Made:
Guided Listing: Converted the host listing flow into a structured, step-by-step experience.
Checkout-Style Booking: Streamlined guest booking into a familiar single-flow checkout.
Early Trust Signals: Surfaced transparent pricing, insurance, and delivery details upfront.
Focus on Primary Actions: Reduced unnecessary decisions by keeping one clear primary action per screen.
