with evidence.
Seven flagship projects. Different technical domains, one selection rule: every project must show how it was tested, measured or validated.

A project is not
the interface alone.
Evidence
Tests, benchmarks, statistical results or a supervised research artifact.
Judgement
The decisions, trade-offs and constraints that explain why the system looks this way.

The proof continues
inside each system.
Open a case study for the architecture, correctness contract, evaluation protocol, security controls, limitations and source material. The portfolio stays deliberately small so every claim can be inspected.
