A route guard and a green pipeline do not stop one customer reading another customer's invoice. Using Angular and a .NET API, I turn a security requirement into server-side ownership checks and tests. Security by design starts with boundaries and evidence, before choosing a scanner.
A new Angular project is an opportunity to make fewer premature decisions. I work through a practical starting point: one useful vertical slice, clear feature boundaries, deliberate state management and tests that protect real behaviour. The goal is a codebase that can grow with the product, without building an imaginary enterprise platform on day one.
