The portfolio decides; the resume gets the portfolio opened. Put the link at the top and make the experience section explain your role in each piece.
Three things, in order of weight.
Portfolio link, working, above the fold
Your specific contribution on team projects
Design system work — components, specs, handoff
Work them into your title, project descriptions and skills — don't pile them into a list.
Each cover is the template itself, rendered.
Gradient page — the resume itself is a work sample.
Strong colour block that still stays readable.
Right-hand rail; different silhouette from every other applicant.
One page. Unless you have 10+ years and a genuinely full second page, the second page only dilutes the first. Put portfolio link, working, above the fold above the fold.
No portfolio link, or one that requires a password with no hint. It is the single most common reason this role gets screened out, and fixing it matters far more than changing templates.
Use AI for the first draft, then verify every claim and number yourself and reorder keywords against the target job description. AI handles speed; the content is still your responsibility.
