AllBooks (Trainers Booking) is a comprehensive booking platform for fitness trainers and their clients. It combines a reservation system, credit system, PWA, and presentation website—a unified portal for both trainers and clients. I architected and built the technical solution. The project includes Google OAuth verification with extended scopes for calendar invites, sync with Google Calendar API, and automated email notifications via SMTP. Product and conceptual direction was developed with partner Oliver Held.
