Flutter Developer to Transform Existing Flutter Web App into a SaaS Platform

I am looking for an experienced developer to help turn my existing Flutter Web app into a fully functional SaaS platform designed for service-based businesses like tattoo shops and artists. The goal is to expand the current single-business demo into a multi-tenant solution with added features and integrations.

???? Demo: Upgrade to see actual info – Please review before applying.

Tech Stack & Future Plans:
Current Stack: Flutter Web + Firebase (for database)
Future Plans: Develop native mobile apps (Flutter)
Database: Currently using Firebase but open to switching to Supabase
Key Features & Requirements:
? Appointment Booking System – Enable seamless scheduling for clients.
? Automated Client Communication – Streamline reminders, confirmations, and follow-ups.
? Consent Forms – Support different forms for various services (e.g., tattoos, piercings, etc.).
? Multi-Tenant Support – Allow multiple businesses to create and manage their accounts.

Integrations:
???? Payment Processing – Support for Stripe & PayPal for membership subscriptions.
???? Calendar Syncing – Integration with Google Calendar, iCal, and other scheduling tools.

Next Steps
???? Review the demo and send a rough quote based on the required features.
?? Applications that do not reference the demo will not be considered due to the high number of automated responses.

If you have experience with Flutter, Firebase, Supabase, SaaS development, and third-party integrations, I’d love to hear from you. Let’s build a powerful platform for service-based businesses together!
