Cadence

Multi-tenant scheduling built for a speech therapy practice and designed for many. Handles the scheduling math humans get wrong: recurring plans, session counts, extensions, and a sessions-remaining badge that is never off by one.

  • /Recurring appointment engine with plan-extension re-anchoring logic
  • /Sessions-remaining computation verified against production edge cases
  • /SMS reminders integrated with the practice's existing number
  • /Staging environment isolated per tenant
