Boarding kennels and daycare facilities run their whole operation from one workspace — clients, pets, spaces, bookings, pricing, invoicing, and team — with self-serve sign-up and a dashboard covering occupancy, arrivals, departures, and unpaid invoices
Isolated every customer with a schema-per-tenant strategy on a single PostgreSQL instance: a tenant schema provisioned automatically at sign-up, requests scoped to it from the authenticated session, and shared concerns (accounts, sessions, tenant registry) kept in a separate public schema
Built the API in NestJS with CQRS per feature, typed SQL and migrations through Drizzle ORM (separate histories for the public schema and the tenant template), and sessions via Better Auth extended to carry tenant and employee identity
Modeled the full stay lifecycle with business-rule validation (capacity, weight fit, overlap prevention, usage-mode fit) and a pricing catalog whose conditional rules snapshot onto a booking at creation, so past invoices never change when pricing changes later
Shipped the frontend in React 19 and TypeScript on Vite with TanStack Query for server state, Tailwind and Radix primitives, English/Spanish i18n, light/dark theming, and fine-grained per-employee permissions enforced at the API layer
Deployed both apps independently on Railway with Neon Postgres, with GitHub Actions CI running build, lint, formatting, unit tests, and end-to-end tests against a real Postgres via Testcontainers
