Full-stack Developer for SaaS Web Application

I’m looking for an experienced full-stack developer or small development team to build and maintain a production-ready SaaS web application.

The project will include:

- Modern responsive frontend
- Secure backend and REST APIs
- User registration, login and role-based access
- Database design and integration
- Admin dashboard
- Third-party API integrations
- Payment/subscription integration where required
- AI/LLM integration where applicable
- Notifications and email workflows
- Secure authentication and data protection
- Deployment, testing and documentation

Preferred technologies include React/Next.js, Node.js or Python/FastAPI, PostgreSQL/MongoDB, REST APIs, Git and cloud deployment. I’m open to recommendations if you have a better architecture.

I’m looking for someone who can understand requirements, suggest a scalable architecture, communicate clearly, and deliver the project in milestones.

Please share relevant SaaS projects you have built, your preferred technology stack, estimated timeline, and milestone-based pricing.
