How I Built an AI-Powered Marketplace Dispute Engine Using React, Flask & AWS ๐Ÿš€

๐Ÿš€ Introduction

Marketplace disputes are one of the biggest pain points in e-commerce platforms.

Most systems still rely heavily on manual workflows:

  • Customers submit complaints
  • Admins review screenshots and proofs
  • Sellers respond manually
  • Resolution takes days

I wanted to explore how AI and automation could improve this process.

So I built an AI-Powered Marketplace Dispute Engine using React, Flask, PostgreSQL, and AWS that helps automate and streamline dispute resolution workflows.


๐Ÿง  What the Project Does

The platform allows:

  • Buyers to raise disputes
  • Sellers to respond with evidence
  • Admins to monitor dispute activity
  • AI workflows to assist in dispute categorization and prioritization

The goal was to create a scalable backend system capable of handling structured dispute workflows efficiently.


โš™๏ธ Tech Stack

Frontend

  • React.js
  • Tailwind CSS

Backend

  • Flask
  • REST APIs
  • JWT Authentication

Database

  • PostgreSQL

Cloud & Deployment

  • AWS App Runner
  • AWS RDS
  • AWS Amplify

Other Tools

  • Git & GitHub
  • Postman
  • AI-assisted workflow experimentation

๐Ÿ—๏ธ System Architecture

The workflow looks something like this:

  1. User creates a dispute request
  2. Backend validates and stores dispute data
  3. Seller receives response request
  4. AI workflow helps categorize dispute priority
  5. Admin dashboard tracks resolution status
  6. Resolution updates are synced in real-time

One of my major goals was keeping the architecture modular and scalable.


๐Ÿ”ฅ Key Features

โœ… Secure Authentication

Implemented JWT-based authentication for secure access management.

โœ… Role-Based Access

Different dashboards and permissions for:

  • Buyers
  • Sellers
  • Admins

โœ… Real-Time Notifications

Integrated real-time notification workflows to instantly update users about:

  • Dispute status changes
  • Seller responses
  • Admin actions
  • Resolution updates

This significantly improved user engagement and tracking efficiency.

โœ… Analytics Dashboard

Built an analytics dashboard to monitor:

  • Total disputes
  • Resolution rates
  • Pending cases
  • Escalation metrics
  • User activity insights

This helps admins better understand platform performance and dispute trends.

โœ… AI-Based Fraud Detection

Implemented AI-assisted fraud detection mechanisms to identify:

  • Suspicious dispute patterns
  • Repeated fraudulent claims
  • High-risk transactions
  • Unusual user behavior

The system helps prioritize potentially risky disputes for faster review.

โœ… Dispute Tracking

Users can monitor:

  • Pending disputes
  • Resolved cases
  • Escalated disputes

โœ… AI-Assisted Categorization

Experimented with AI workflows to:

  • Identify dispute type
  • Prioritize urgent cases
  • Improve admin efficiency

โœ… Cloud Deployment

Deployed the application using AWS services for scalability and reliability.

โ˜๏ธ AWS Services Used

AWS Amplify

Used for frontend deployment and hosting.

AWS App Runner

Handled backend container deployment with simplified scaling.

AWS RDS

Managed PostgreSQL database hosting.

Working with cloud deployment taught me a lot about:

  • Environment variables
  • Deployment pipelines
  • Backend connectivity
  • Production debugging

๐Ÿšง Challenges I Faced

Like every real-world project, this one came with challenges.

Some major ones were:

  • Handling authentication securely
  • Managing API communication between frontend and backend
  • Database relationship design
  • Deployment configuration issues
  • Backend service connection with PostgreSQL
  • Debugging production errors on AWS

A lot of time went into debugging deployment and API issues rather than writing features ๐Ÿ˜…


๐Ÿ“š What I Learned

This project helped me gain practical experience in:

  • Full-stack development
  • Cloud deployment
  • Backend architecture
  • Database design
  • API development
  • Authentication systems
  • AI-assisted workflows

More importantly, it taught me how real production systems require much more than just writing code.


๐Ÿ”ฎ Future Improvements

Some features Iโ€™d like to add next:

  • AI-generated dispute summaries
  • Payment gateway integration
  • Multi-language support

๐Ÿ’ก Final Thoughts

Building this project was a great learning experience because it combined:

  • Full-stack engineering
  • Cloud infrastructure
  • Backend systems
  • AI experimentation

Iโ€™m still improving the platform and exploring new ideas around AI-powered automation systems.

Would love to hear feedback or suggestions from the community ๐Ÿš€
