Portfolio Rank

The goal - what I'm exploring

A list of 2,000 portfolios sorted alphabetically is a phone book: nobody can find the good ones. Portfolio Rank asks what it takes to turn a giant community list into something fun to browse, and what keeps a crowd-voted leaderboard honest enough to trust.

How it uses AI

Gemini bootstraps the rankings: it judges portfolios pairwise on design and content, so the leaderboard means something before people have voted, then human votes take over through ELO. It also grades each site on a 6-axis rubric, shown beside objective Lighthouse scores, so the AI's opinion is never the only signal.

How it works

• Built on Emma Bostian's developer-portfolios list, a community resource since 2019, sorted A to Z. Portfolio Rank gives it a real frontend and a ranking system, so you can find the good ones.
• Face-off voting: two portfolios side by side, pick the better one, and ELO decides the leaderboard. Ten practice votes need no account; official votes take a GitHub sign-in, one per person per matchup.
• Rankings start from AI: Gemini judges portfolios head to head, so the leaderboard is useful before human votes pile up, then the crowd takes over.
• Every site gets a real screenshot, Lighthouse scores from PageSpeed Insights, polish checks and an AI review on a 6-axis rubric.
• Vote integrity is guarded hardest: a UNIQUE constraint and a single write transaction, so concurrent requests cannot race past the duplicate check or the daily cap.
• The pipeline runs itself: daily GitHub Actions sync the upstream list, judge new matchups and refresh screenshots and scores.
