Case Study — UX Design
Mahi
Restaurant
An online ordering app that makes it easy to customise your meal, check out fast, and track your delivery in real time. Designed for Google’s UX Certification with a focus on accessibility and user research.
The Problem
Less customisation, longer checkouts.
Existing food ordering apps gave users little control over ingredients and buried checkout behind too many steps. Mahi was designed to fix both — letting customers customise freely and get to confirmation in seconds.
User Research
Through interviews and surveys with daily food app users, three core pain points emerged. Users with busy schedules struggled most with time constraints: long delivery waits, no advance planning tools, and slow checkout flows made the experience frustrating. Accessibility was another recurring issue — users couldn’t reach delivery personnel, estimates were unreliable, and restaurant options felt limited. Finally, interface and usability problems including text-heavy menus, confusing layouts, and difficulty finding specific dishes made ordering feel like a chore. These findings directly shaped the design direction for Mahi.
Personas
I conducted interviews and took numerous surveys to understand daily users who order food online and don’t have time to cook their meals. I observed that people with a tight schedule often order online and need their orders to reach on time and know the delivery location and estimated time.
