Domain boundaries
Client portal, CRM, back office, payments, risk, and reporting are treated as capabilities with contracts — not a single monolithic admin.
Integration spine
APIs, events, and sync jobs are designed with ownership, versioning, and failure handling from the start.
Environments & promotion
Build, UAT, and production separation protects desks from untested change.
Security posture
Least privilege, server-side validation, secret management via environment configuration, and honest communication about what is verified.
