Technical portfolios often collapse design intent and demonstrated results into the same list. This site takes a different approach: a named tool is not evidence that a control works, and a dashboard is not proof of an operating process.
Start with the claim boundary
The backend experience described here is professional background. The initial DevSecOps case studies are plans for structured labs. Their status labels make that boundary visible before a reader reaches the details.
Define evidence before implementation
Each case-study model asks for a problem, threat model, architecture, trade-offs, controls, validation, evidence, measurements, limitations, and improvements. Empty evidence is stated plainly. This prevents a planned scanner or alert from quietly becoming a claimed result.
Make the portfolio inspectable
The site itself is a small example of the same practice: source-controlled content, schema validation, static output, automated checks, minimal workflow permissions, and deployment from a reviewed build artifact. Those controls still have limits, which are documented rather than hidden.
What comes next
The first implementation target is the secure delivery pipeline. Its synthetic failure cases and evidence format should be designed before adding the scanner list.
