1 / 9Challenge
The client needed a P2P vehicle and equipment rental marketplace serving Egypt and Ecuador — one Flutter app serving two completely different user types: owners who list and manage their vehicles, and renters who discover and book them. Both roles had to coexist in a single app without two separate codebases. Beyond development, the client needed the full product delivered from scratch: PRD, SRS, screen specifications, logo, and a complete custom icon set — none of which existed at project start.
Solution
I delivered both the full product design and the Flutter implementation. App architecture — dual role in a single codebase: The app uses an activeMode system managed in AppController (GetX). When a user switches between Owner and Renter mode, the bottom navigation, home screen, and available actions all update reactively — one codebase, one binary, two complete experiences. Shared screens (profile, notifications, settings) use role-aware scaffolds that adapt their content based on current mode rather than duplicating screens. Design deliverables: Full PRD and SRS covering business logic, user flows, and feature specifications for both roles. Figma screen specs for 31+ mobile screens and a 32-screen Flutter Web admin panel. Custom logo: amber location pin with a V mark cutout, Plus Jakarta Sans wordmark, amber/teal/cream colour palette. 93 custom SVG icons across 9 category folders and 15 custom screen illustrations for empty states, onboarding, and feature highlights. Firebase backend: Firestore for listings, bookings, and user profiles. FCM for booking notifications. Firebase Auth with Google Sign-In. Role-based Firestore security rules. Also performed a targeted upgrade pass replacing all deprecated WillPopScope usage with PopScope after a Flutter SDK update.
Outcome
Delivered a complete product: full Flutter dual-role app, Firebase backend, Flutter Web admin panel Figma spec, PRD, SRS, logo, 93 SVG icons, and 15 illustrations — everything needed to take the product to launch or to hand off to a wider team. One of the most comprehensive single-project deliveries I've done, spanning product strategy, design, and engineering end to end.
What I worked on
Architected the dual-role app using an activeMode system in AppController — one codebase, two complete user experiences.
