Keep business rules on the server
Policies govern access to appointments and conversations. Role and office boundaries are enforced in the API so the interface is not the authority for access.

The operational problem
A consultation platform needs to coordinate more than a calendar. Clients, consultants and administrators interact with the same appointments, while payments, conversations and background processing must follow consistent rules.
SooJustAsk brings these workflows into a multi-tenant platform, with explicit business policies and separate workers for appointment lifecycle, notifications and translation.
What the product does
- Client, consultant and administrator workflows.
- Appointment lifecycle, credits and payment processing logic.
- Real-time chat, translation, moderation, notifications and reporting.
Engineering decisions
Give background work its own lifecycle
Appointment, notification and translation workers use queue-backed processing. Long-running and retryable work is kept separate from the browser request lifecycle.
Handle payment callbacks deliberately
Payment logic verifies provider callbacks and accounts for already-processed events. Credits and payment state are part of the domain, not just a successful checkout screen.
Reliability and maintenance
- Service tests for auth, appointments, payments, chat and administrative workflows.
- Container and release-verification checks in the delivery workflow.
- Backup and restore-drill tooling with dedicated operations documentation.
Testing and delivery
The workspace contains a React/Vite frontend, an Express API, shared contracts and database libraries, and background workers. CI includes typechecking, critical backend tests, application and container builds, and release verification. A complete container smoke cycle is available as an explicit opt-in check.
