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