OFF Studio

PWA for contrast therapy (sauna + cold plunge) bookings. Combines reservation system, credit-based payments, and presentation website in one platform. Three role-based interfaces: reception view for check-ins, admin dashboard, and client zone for booking and QR access. Architecture spans three services—one of them Python—with proper timezone handling between server and client. Stripe, Auth.js, Google OAuth, email queue, QR generation and scanning.
