Scalable Gym Management Platform Development

I am writing to request a proposal/quote for the development of a gym management system based on the following project specifications:

1.⁠ ⁠Web App for Gym Staff

- Gym sign-up and configuration settings
- Staff login with role-based access (Owner, Front Desk, Trainer)
- Member management, membership plans, and renewals
- Membership freeze options, upgrades, and discounts
- Tracking payments, invoices, and expenses (recording cash, UPI, or bank transfer)
- Attendance tracking via biometric devices (ZKTeco/eSSL), QR code, or manual entry
- Class scheduling and booking
- Lead/Enquiry management with a daily follow-up list
- Custom workout and diet plans created by trainers
- Owner dashboard, detailed analytics/reports, and Excel/CSV data exports
- Support for both light and dark modes

2.⁠ ⁠Member Mobile App (iOS & Android)

- Sign-in via One-Time Password (OTP)
- View membership status, expiry dates, and payment history
- Attendance check-in via QR code
- Class booking feature
- Access to assigned workout and diet plans
- Push notifications for upcoming renewals and general gym updates

3.⁠ ⁠Preferred Technology Stack

- Web App: Next.js (TypeScript)
- Database: PostgreSQL
- Mobile App: React Native
(Please let us know if you suggest an alternative tech stack based on these requirements).

4.⁠ ⁠Project Scale & Growth

Please let me know your availability for a call to discuss the timeline, estimated budget, and any initial feedback you might have on these requirements.

Looking forward to hearing from you.
