Defensible by designDecisions remain reviewable and evidenced.
Transparent processScope, ownership and boundaries stay visible.
Client-first partnershipWork starts with the operating need.
Secure by defaultAccess and sensitive data stay controlled.Understand persistence boundaries, repositories, transactions, migrations, consistency, caches, and data contracts before the database becomes the hidden architecture of the application.
