    About this skill

    Architecture decisions made in week one constrain you for years. This skill designs the full technical foundation for a SaaS product: data model and schema, auth and authorisation (RBAC, multi-tenancy), REST or GraphQL API contract, frontend component architecture, billing integration pattern, background job design, and security posture. Returns an Architecture Decision Record, annotated data model, API spec skeleton, and a launch-day checklist. Specify your stack, scale target and must-haves — it surfaces the structural decisions most teams only discover they got wrong at Series A.
