Projects

How this site is built

A commit to cv.yaml runs the cv repo workflow on GitHub Actions: it renders the HTML, prints the PDF with Playwright and deploys cv.nguyendinhkha.com to Cloudflare Pages. It then sends a cv-updated event to the portfolio repo (a daily scheduled build is the fallback). The portfolio build fetches cv.json, builds this Astro site and deploys nguyendinhkha.com, where /api/contact is a Pages Function that sends the contact form through Resend.
