Transform Existing Replit App into Comme

Project Overview
I have developed a functional web application on Replit and now require an experienced full-stack developer / SaaS architect to transform it into a secure, scalable, commercial-grade SaaS application.
The objective is to migrate the existing Replit-developed application into a fully production-ready SaaS platform with proper hosting, security, user management, subscription billing, scalability, and enterprise-grade architecture.
This is not a build-from-scratch project — it is a professional productization and commercialization task.
Scope of Work1. Codebase Review & Refactoring
Audit current Replit app architecture
Refactor for production readiness
Optimize backend structure
Improve modularity and scalability
Remove Replit-specific dependencies
2. SaaS Architecture Design

Organization-based data isolation
Secure authentication (JWT / OAuth / SSO readiness)
3. Hosting & Deployment
Cloud deployment (AWS / Azure / GCP preferred)
Domain setup
SSL certificate
CI/CD pipeline
Staging & production environments
Containerization (Docker preferred)
4. Database & Infrastructure
