3arabawy

Overview

3arabawy is a large-scale automotive marketplace for Egypt covering car and motorcycle sales, rentals, services, and spare parts — with real-time chat, purchase requests, a virtual coin economy, and an AI car-price guide. The app is media-heavy by nature: thousands of photo listings uploaded from every class of device, which made performance engineering the core of the work.

The Challenge

Heavy image uploads were causing out-of-memory crashes and UI jank on the low-end Android devices most of the market actually uses, and Arabic search had to cope with Unicode inconsistencies and diacritics that broke matching.

Our Approach

1. 01

   Rebuild the media pipeline

   Refactored image compression and networking to native file streams with path-based compression in C++/Objective-C sub-workers instead of Dart-side byte processing — cutting RAM usage by ~98% and eliminating OOM crashes.

2. 02

   Re-architect

   Spearheaded the transition to a modular, event-driven Flutter architecture with Clean Architecture layering to handle complex app states efficiently.

3. 03

   Go real-time

   Led the integration of a Socket.IO microservice for chat and live interactions, collaborating with the backend team on API contracts and data-sync design.

4. 04

   Polish for the market

   Normalized Arabic search (diacritics removal, Unicode folding) and stripped heavy blur rendering from list views, moving rich rendering to preview screens for fast scrolling.
