Architecture Review Checklist

The checks I run on a SaaS codebase. Tick them off; progress saves in this browser.

0 of 20 done

DeliveryBuilds are reproducible (containerised, pinned dependencies).Tests run automatically and block a broken release.Promotion to production needs no manual steps.A release can be rolled back in minutes.

SecurityOne authentication model across the product.Refresh tokens rotate and can be revoked.Credential endpoints are rate limited per IP and per account.Roles follow least privilege; admin access is audited.Secrets live in a secret store, never in the repo.

DataHot queries are backed by the right indexes.Repeated reads are cached where it is safe.Backups are tested by actually restoring them.Tenant data cannot leak across tenants.

OperationsLogs are centralised and searchable.Alerts fire on symptoms users feel, not just CPU.Compute is sized to real load, not a guess.There is a written runbook for the top incidents.

TeamArchitecture decisions are written down with their reasons.Code review is routine, not optional.A new engineer can ship in their first week.
