Full-Stack E-commerce Developer: Custom Multi-Vendor CMS (PHP/Laravel) & High-Performance Flutter App

Project Overview

Our Goal: A faster, more scalable multi-vendor marketplace platform.

We are currently operating a multi-vendor e-commerce platform using Active E-commerce CMS and its Flutter app. While the feature set is solid, the current solution is proving to be heavy, slow, and lacks the performance and scalability we require for a growing user base.

We are looking for an experienced Full-Stack Developer or Development Team to build a custom, lightweight, and high-performance replacement solution that maintains the core functionality of a multi-vendor marketplace but is significantly faster and more robust.

The project requires development of two core components that communicate seamlessly:

Custom Back-end CMS & API (Preference for PHP/Laravel for ease of management and deployment).

Cross-Platform Mobile Application (Must be built with Flutter for iOS & Android).

3. Scope of Work & Deliverables

The final deliverable is a complete, market-ready, and high-performance multi-vendor e-commerce platform with all three user panels (Admin, Seller, Customer).

A. Custom E-commerce CMS & Admin Panel (Back-end)

Performance Optimization: The primary goal is a lightweight script with optimized database queries and efficient caching mechanisms for rapid response times.

Multi-Vendor System:

Vendor registration, approval process, and separate vendor dashboard.

Vendor product management, inventory, and order fulfillment.

Commission and payout management system.

Core E-commerce Features:

Product management (variants, inventory, digital/physical products).

Dynamic homepage and content management.

Order management (tracking, status updates, order history).

Multiple payment gateway integration (e.g., PayPal, Stripe, and a few local options).

Shipping and tax configuration.

B. High-Performance Mobile Application (Flutter)

Customer App (iOS & Android):

Smooth, fast, and responsive user interface (minimal loading times).

User authentication (social login, standard email/password).

Advanced product search, filtering, and sorting.

Shopping cart, wishlist, and seamless checkout process.

Product reviews and ratings with image/video upload support.

Real-time notifications (Push Notifications).

Seller App (Optional/Phase 2 - Please specify in proposal):

Simplified dashboard to track sales, orders, and earnings.

Ability to update inventory and change order status.

4. Required Expertise & Technology Stack

We are looking for a developer or team with a proven track record in building large-scale, high-performance e-commerce platforms.

Mandatory Skills:

Custom CMS/Back-end: Strong expertise in PHP/Laravel development.

Mobile App: Expert-level proficiency in Flutter for cross-platform mobile development.

Performance & Database: Deep understanding of database optimization (e.g., MySQL/PostgreSQL) and API development (RESTful APIs) for high speed and low latency.

Version Control: Git/GitHub/GitLab workflow experience.

Preferred/Bonus Skills:

Experience in optimizing existing large-scale e-commerce systems.

Familiarity with cloud services (AWS/Google Cloud/Digital Ocean) for deployment.

Experience with advanced state management in Flutter (e.g., Provider, Riverpod, Bloc).

5. To Submit a Proposal

To be considered for this project, please include the following in your proposal:

Portfolio/Case Studies: Links to at least two (2) live or recently completed multi-vendor e-commerce or marketplace projects, highlighting both the web CMS and the mobile app.

Performance Strategy: Briefly describe your approach to ensure the new platform is significantly faster and more performant than the existing solution (e.g., what technologies/techniques will you use for caching, database, and Flutter optimization?).

Project Timeline (Estimate): Provide an estimated timeline for the full delivery of the CMS and Customer App MVP.

Pricing Model: Indicate your preferred pricing (fixed price for the full project or hourly rate) and a preliminary cost estimate.

We are looking for a reliable, communicative partner who can deliver a polished, fast, and scalable final product. We look forward to reviewing your proposals!
