Secure Access System for Roth Conversion Tool

We’ve already built our proprietary Roth conversion tool (Roth Roadmap). Now we need a developer to help us build a secure access system around it.

We’re looking for someone to create:

What You’ll Build:
A secure login system (Firebase Auth or similar) so users must log in to access the tool

A PayPal integration for payment (one-time or subscription) — no Stripe

A way to link payment to access — e.g., after PayPal payment, mark the user as "paid" and allow login

Protection against link sharing (token/session security, route protection, no direct access without login)

Optional: lightweight admin panel to manage user access (view, revoke, reset)
Tools We’re Open To:
Auth: Firebase Auth, Supabase, or similar

Backend: Node.js, Supabase, Firebase, or your recommendation

Frontend Hosting: We’re on GHL for the marketing page but tool can be hosted on Vercel, Netlify, etc.

Additional Notes:
Our landing page is on GoHighLevel, so you don’t need to build that.

We just need a secure paywall + login to gate access to our hosted tool.

We prefer PayPal, so only apply if you're confident in securely handling PayPal payments and access logic.

Timeline:
2–3 weeks max



To Apply:
