Case Study: Listing Builder Pro

Overview

Listing Builder Pro is a SaaS platform designed for Amazon sellers to optimize their listings using AI-driven tools. The project required building a comprehensive solution from scratch, including listing optimization features, multi-tenant architecture, billing integration, and an AI generation backend.

The Challenge

• Develop a scalable multi-tenant system capable of handling thousands of listings daily.
• Implement advanced listing optimization algorithms powered by AI.
• Integrate Stripe for seamless billing management.
• Ensure robust data security and compliance with Amazon guidelines.
• Deliver a user-friendly dashboard for sellers to manage their listings efficiently.

The Solution

1. Backend Development: Built the core backend using FastAPI, ensuring high performance and scalability.
2. Frontend Dashboard: Developed a Next.js-based dashboard providing intuitive interfaces for sellers to interact with the platform.
3. Multi-Tenant Architecture: Implemented a multi-tenant setup in Postgres, optimizing database management and security across multiple users.
4. AI Integration: Integrated Gemini 2.5 Pro for AI-driven listing optimization, enhancing content quality and relevance.
5. Billing System: Set up Stripe integration to handle billing processes seamlessly, supporting subscription models.
6. Task Queue Management: Utilized Bull queue system with Redis for efficient task management and background processing.

Results

• MVP launched in 3 weeks; full production hardening completed in 7 weeks total.
• Multi-tenant architecture validated — handles thousands of concurrent listing optimizations.
• Stripe billing integration in place — subscription model live from day 1.
• Background job queue processes long-running AI generations without blocking user requests.
