Astro portfolio website: 100 for accessibility and SEO on mobile

sabinmainali.pages.dev is my portfolio website. I built it with Astro and Tailwind CSS and host it on Cloudflare Pages. On 24 September 2026 I ran Google Lighthouse 3 times on the live home page in mobile mode. It scored 93 to 95 for performance and 100 for accessibility, best practices and SEO. The work was AI-assisted with Claude Code and human-checked.

I needed one place where a client can see my work, read how I work and send me a brief. It had to load fast on a phone. It had to be easy for Google and AI answer engines to read. And hosting had to cost as little as possible.

14 public pages: home, work, 7 case studies, services, AI Lab, about, CV and contact.

The text lives in one data file and one file per case study, so a new case study starts as a copy of an old one.

Search basics on every page: a title, a meta description and a canonical link. The site also has a sitemap, structured data (JSON-LD) for the person, the website and the FAQs, an llms.txt file for AI tools and a generated social preview image for each case study.

A contact form that sends briefs through Web3Forms.

Self-hosted fonts, so a visitor's browser does not call a font service.

Every push to GitHub builds the site and deploys it to Cloudflare Pages through GitHub Actions.

Every deploy runs a check script first. The deploy stops if the script finds any of these:

non-ASCII punctuation in the text

invalid structured data

a broken internal link or anchor

a page without exactly one main heading

missing meta tags

words that suggest confidential employer data

Security headers are set on every page, including a content security policy and HSTS. After deploy I test the live page in Lighthouse.

Lighthouse, mobile mode, live home page, 3 runs on 24 September 2026:

Performance: 93, 94 and 95

Accessibility: 100

Best practices: 100

SEO: 100

Cumulative layout shift: 0. Total blocking time: 0 ms. Largest contentful paint: 2.2 to 2.5 seconds.

Hosting is on Cloudflare Pages, chosen because its free plan has unlimited requests and bandwidth.
