I Built an AI Services Storefront Powered by 15+ Models — Here is How

The Problem

Most AI services are either:

  • Expensive enterprise contracts ($10K+)
  • DIY "just use ChatGPT" (no quality control)

There's nothing in between for developers and small businesses who need professional AI work done fast.

What I Built

Susan AI — a self-service storefront where you can buy AI-powered services with Stripe and get results delivered automatically.

Services Available

Service Price Delivery
Quick Security Scan $149 24 hours
Technical Translation (100+ languages) $99 48 hours
Security Audit + Fix List $399 3-5 days
Weekly Content Pack $299/mo Weekly
AI Chatbot Setup $750 5-7 days
Managed AI Ops $2,499/mo Ongoing

The Tech Stack

  • Backend: Node.js + Express on Railway
  • AI: 15+ models including Llama, Qwen, DeepSeek, Aya (for translation)
  • Payments: Stripe Checkout with webhook fulfillment
  • Free LLM Providers: Groq, Cerebras, SambaNova (zero-cost inference)
  • Monitoring: Telegram alerts for orders, health checks, escalations

How Auto-Fulfillment Works

  1. Customer buys a service via Stripe
  2. Webhook fires -> order created in SQLite
  3. AI model generates the deliverable (code review, translation, content)
  4. Result saved + customer notified
  5. Health daemon checks every 4 hours for stuck orders

The entire pipeline runs autonomously. I get a Telegram notification when an order comes in and when it is fulfilled.

Free Bonus

Every $99+ purchase includes a free Pocket Linguist Pro subscription — an AI language learning app with 40+ languages.
