## README.md

Parkio manages vehicle entry, stay, exit and payment at parking lots. Each customer is an independent organization with its own lots, users, rates and reports, and several operators work on the same tickets at once from different phones.

The backend is a modular monolith in Java 21 and Spring Boot with hexagonal architecture and DDD; architecture rules are enforced with ArchUnit. PostgreSQL isolates each organization's data with Row-Level Security, and Redis with STOMP WebSockets keeps operators in sync.

Four clients share the same API: the operator mobile app (React Native with Expo), the business dashboard and the SaaS provider panel (Angular), and the public landing page in Astro.
