Full Stack Developer Needed — Polish & Final QA for Junk Removal Funnel (Firebase + Stripe)

Project Status:
All core features are already built and working!
We have a multi-step booking funnel (HTML/JS), Firebase Firestore backend, and Stripe checkout integration.
You’ll join as a “finisher”: test, debug, polish, and help us ship the MVP.

Your Mission
• Test the full flow: lead capture → Stripe checkout → booking creation
• Catch and fix small bugs (e.g., edge cases, validation, error handling)
• Tune UI (responsive tweaks, better loader/spinner, copy, field order, etc.)
• Polish backend (ensure no undefined in Firestore, check webhooks, etc.)
• Make sure “leads” and “bookings” collections are written correctly (status, metadata, etc.)
• Support Stripe/webhook/FireStore “gotchas” and polish integration with contractor app (for ops/admins)

Make your the entire Ops is working properly from A to Z without any issues, Error or bugs

The Stack
• Frontend: HTML, CSS, Vanilla JS (no frameworks)
• Backend: Node.js (Express), Stripe, Firebase Firestore
• Infra: Railway (backend), Firebase Hosting (frontend)

What We Already Have
• Clean repo, all code working
• Hosted backend (Railway) and frontend (Firebase Hosting)
• Stripe/Firestore set up and tested
• Contractor/ops app for CRM

What You’ll Do
• Final testing and polish (make sure every field is saved right)
• Check all handoffs (lead → booking, checkout → webhook)
• Advise on Firestore rules (if needed)
• Make sure contractors/ops can see new jobs
• Answer a few quick questions and help with launch (by Telegram or Discord)

You Are:
• A detail-oriented dev who loves clean, simple code
• Strong with Node, Express, Firestore, and Stripe APIs
• Fast, responsive, and proactive — you like launching things!

This is NOT a rebuild!
Just help us get it from “almost done” to “fully launched and smooth.”
