About this site
This portfolio is a project in itself: a motherboard where each component opens a part of my profile.
How it was built
- With spec-driven development (SDD): every feature was first written as a specification with verifiable acceptance criteria.
- Every automated criterion has a test that cites it, and a traceability check prevents a feature from being marked as done without them.
- Built with AI assistance, with the specifications as the source of truth.

What you do not see
- Static site: no application server, no database and no cookies.
- Fully navigable by keyboard and screen reader, conforming to WCAG 2.2 AA.
- Without JavaScript, or on a phone, the same content is shown as a plain page.
The image
The motherboard photograph and its sketch version were generated with AI and upscaled to high resolution; the interactive areas and the auras are drawn in code on top of them.
