AI Image SaaS — Full Stack Platform
Commercial AI image transformation platform with Stripe payments and credits architecture
Project Overview
A commercial Software-as-a-Service application delivering automated AI image manipulation—including generative fill, background removal, object recoloring, and image restoration—coupled with a transactional credit balance and Stripe checkout.
Event-Driven Asynchronous Processing & Ledger Pipeline
Built around asynchronous image transformation pipelines, webhook event reconciliation, and transactional credit deductions guaranteeing idempotency.
- Stripe webhook handler with signature verification and atomic database balance mutations.
- Cloudinary AI integration for deterministic parameter-based transformation pipelines.
- Optimistic transformation previews paired with server-side download asset signing.
Engineering Challenges & Solutions
Preventing double-spend of user transformation credits
Implemented atomic transactional mutations with distributed locking so credit deductions and transformation jobs execute as a unified atomic unit.
Processing large image transformations without request timeouts
Architected an asynchronous job queue delegating heavy generative rendering to background workers while polling completion status via serverless hooks.
Core Capabilities
- AI-powered generative fill extending canvas boundaries seamlessly
- Precise semantic object removal and background isolation
- Multi-tier credit subscription packages with Stripe Checkout and Customer Portal
- User transformation history archive with direct high-resolution download links
Validated Outcomes
- 100% webhook transaction reconciliation with zero duplicate charge reports
- Average transformation dispatch time reduced to under 1.2 seconds
- Secure asset URL signing preventing unauthorized CDN bandwidth consumption
