Booking / Scheduling (Next.js, Prisma, Stripe, Redis, TypeScript) overview

A booking and appointment scheduling platform using Next.js for a responsive calendar interface with server-side rendering for SEO-friendly public booking pages. Prisma provides type-safe database access to PostgreSQL for managing availability, bookings, and customer profiles. Stripe handles payment collection, deposits, and cancellation refunds. Redis manages distributed locks for preventing double-bookings during concurrent reservation attempts. Google Calendar API integration enables two-way sync with providers' personal calendars. Designed for SaaS companies building scheduling tools for salons, clinics, consultants, and service businesses.
