Bunkie UI case study by Victor Omolasoye, Product Designer (UI/UX) —
Mobile Marketplace App Design
Overview
The Bunkie mobile app lets people list items, discover what's nearby, send and receive requests, and manage a verified profile. The work covers the full interface across onboarding, discovery, listings, identity verification and settings.
Problem & Solution
The Problem
Bunkie needed a clear, trustworthy mobile experience for a marketplace built on user-to-user listings. New users had to understand how to browse, list and send requests quickly, while the product also had to verify identity before anyone could transact.
The Solution
A mobile UI spanning splash, onboarding, sign up and sign in, discovery, listings and requests, saved items, a guided create-listing flow, and a multi-step identity verification flow (ID, selfie and a short behaviour matrix) to build trust before transacting.

Key Features

Listings & Requests
A guided multi-step create-listing flow, plus screens to track your listings and the requests you send and receive.

Design Approach
The UI was designed around the core marketplace loop: browse, list and transact. Each flow was kept short and legible, with a consistent component set and clear empty, loading and success states so users always know what happens next.
