Convert my SaaS Prototype to a Production ready Application:

I have a working prototype built with TypeScript, Java and React and I’m ready to turn it into a fully-featured SaaS platform. The core stack will stay the same, but I now need solid PostgreSQL architecture, robust user security, and clean Stripe billing integration.

Key functionality already mapped out includes:
• User security and database management that supports six distinct roles—Admin, Regular User, Guest, Recruiter, Agency and Super Admin—each with clearly defined permissions.
• Billing through Stripe with plan creation, proration, webhooks and automated invoicing.
• End-to-end background and credential verification: storing documents securely, exposing API endpoints for partners, and surfacing status updates to users.
• AI-driven workflow automation so actions such as onboarding, reminders and status changes fire automatically without manual touch points.

The prototype codebase can be shared immediately via GitHub, along with an ERD, I’d like to keep the engagement on an hourly basis, so please include your rate and examples of comparable SaaS builds—especially anything involving verification workflows, multi-role security or Stripe.

My goal is a production-ready app with CI/CD, basic monitoring and clear hand-off documentation. If you have the experience to harden the stack, wire in the AI workflows and make the user experience seamless, I’m ready to start. Some graphic design work and mockups for new pages will be required.

Ideal candidate will have about 30 hours per week available for 8-10 weeks. Note: Complete billing workflow for payment and usage will be needed since there will be metered services (subscription) and one-time. Proper tokenization for re-occurring expenses will be required.
