Motivation

The goal was to create a mobile app that replaces the offline market for buying and selling auto parts, addressing the customer’s pain points of limited reach, inefficient searches, and time-consuming offline transactions. The platform needed to be intuitive and user-friendly, enabling buyers to quickly find parts with advanced filters and sellers to respond efficiently. Azati’s task included implementing business logic, designing the application map, and creating a modern, minimalistic UI that maximizes usability and satisfaction for a niche audience of car enthusiasts.

Main Challenges

Challenge 01
Tight Deadlines

The project had extremely tight deadlines of only 8-10 days for the full design, requiring rapid development without compromising quality. This limited the time available for user research, usability testing, or detailed market analysis, forcing designers to rely on experience and rapid iteration to deliver an effective solution.

#1
Challenge 02
Niche Audience Understanding

The target users were a very specific group of car enthusiasts and auto parts professionals. Understanding their preferences and behavior was challenging due to the limited time for market research. Designers had to create a solution that resonates with this narrow demographic while ensuring usability and clarity for first-time users.

#2
Challenge 03
Complex Buyer-Seller Interaction

Designing a seamless interaction between buyers and sellers posed a challenge. Buyers needed to generate offers quickly using filters, and sellers had to respond with product details and pricing. The interface needed to minimize confusion, provide clear communication, and guide users through each step of the transaction process despite the complexity of interactions.
