Build an iOS and Android App for a Mobile Pet Grooming Business

"We run a growing mobile pet grooming service and currently manage appointments, customer details, staff schedules, and payments through a combination of spreadsheets, text messages, and separate booking tools. We want to replace this process with a simple mobile app that makes it easier for customers to book services and for our groomers to manage their daily routes. The first version should be a practical MVP that can support future expansion into additional cities. What We Need We are looking for a developer or small team to build a cross-platform React Native application for iOS and Android, along with a lightweight web-based admin panel. Customer features should include: - Account registration and secure login - Pet profiles with breed, age, notes, and photos - Service selection and appointment booking - Available time slots based on location - Stripe payment integration - Appointment reminders and push notifications - Booking history and account settings Groomers will need a separate role where they can view assigned appointments, update job status, add service notes, upload photos, and contact customers. Backend and Admin We need a secure and scalable backend with REST APIs, role-based permissions, and reliable scheduling logic. We are open to Node.js with PostgreSQL, Firebase, or Supabase if you can explain the tradeoffs. The admin dashboard should allow our team to manage customers, groomers, service areas, pricing, bookings, and payment status. Initial Deliverables The first milestone should include the technical plan, UI/UX wireframes, database structure, and a working booking flow. Final delivery should include App Store and Google Play deployment support, source code, and basic technical documentation. To Apply Please start your proposal with the word PAWS and include: - Links to live iOS or Android apps you have built - Your role on each project - Experience with React Native and Stripe - Your recommended backend architecture - Estimated timeline and cost for the MVP How would you prevent double bookings while keeping appointment availability accurate?"
