The site itself as the technical argument: single-source theme, in-browser PDF résumé and a live repository showcase.

The problem

A career-changing developer needs to prove competence without industry job history — so the site itself becomes the technical argument.

What I built

A Next.js one-pager with a single-source theme (one file drives the site, OG banner and manifest), a PDF résumé generated in the browser, a live repository showcase via the GitHub API, a PT/EN version and a three.js 3D scene.

What I learned

Performance as a requirement (LCP, bundle, reduced-motion) and end-to-end AA accessibility.
