Backend Dev (Resume Scorer SaaS) – Stripe, GPT, Firebase | Ongoing Projects

Job ID: 39374533

Budget: $30 – $250 USD

I’ve built a clean UI for a Resume Scorer SaaS tool using v0.dev, now hosted on Vercel. I need an experienced backend developer to integrate GPT-4, Stripe payments, and access control. If you're efficient and deliver clean work, I’ll send you multiple projects per month (simple tools with great UX and Stripe monetization — $100+ per project).

What’s Already Done
Frontend built with v0.dev

Hosted on Vercel

Stripe one-time payment link is ready

v0.dev Pro access + GitHub invite will be provided

Responsibilities
Integrate resume upload with GPT-4 (via OpenAI API) and return a structured score + improvement suggestions

Handle Stripe payments:

Use existing $9 one-time checkout link

Set up $12/month subscription via Stripe Checkout

Build webhook listener to update user status: free, paid_once, or subscriber

Add user authentication (magic link or email login via Clerk, Firebase, or Auth0)

Store user status in Firebase, Supabase, or Vercel KV

Unlock full report only for paid users

Push backend code to GitHub and deploy to Vercel backend functions

Tech Stack
Node.js, TypeScript, Express or Vercel API routes

Stripe (checkout, subscriptions, webhooks)

Firebase or Supabase for auth and user metadata

GPT-4 / OpenAI API usage

GitHub for version control

Bonus: Experience with v0.dev exports or Tailwind frontend cleanup

Project Scope
Resume Scorer with Stripe monetization and GPT analysis

All UI, GPT prompts, and payment links will be provided

Timeline: 5–7 days max

Budget
$100 fixed

Bonus available for clean and early delivery

More projects ready immediately after (SEO tool, contract filler, etc.)

Long-Term Opportunity
I'm launching 10–15 micro SaaS tools with Stripe + AI integrations. If you're:

Fast, clean, and reliable

Great with APIs and integrations

Comfortable working independently

Then I’ll send you 1–2 projects per week at $100+ each.
