How this platform is built

This frontend

A static application containing no calculation engine and no backend secret. It uses OIDC Authorization Code with PKCE, refreshes sessions, and polls queued jobs through the API.

Durable backend jobs

Heavy calculations and all controlled exports run through a queue with a separate worker service, progress reporting, bounded retries, cancellation and terminal failure records.

Login and database

Named-user login is issued by the identity server. PostgreSQL stores organisations, seats, subscriptions, immutable project versions, jobs, exports and audit records.

Payments

Checkout, billing, signed webhooks and the customer portal automate per-seat subscriptions and entitlement changes.

Operations

Metrics, dashboards, alert rules, structured logs, rate limits, verified backups, restore tooling and controlled deployment workflows ship with the backend.

Commissioning boundary

Account deployment, alert receivers, live payment and tax approval, identity SMTP and MFA, load tests, restore drills and independent penetration testing require the production environment.
