Website rebuilt from Canva into a fast static site that non-technical staff edit themselves.
Role: Design and development
Full rebuild of the website of a non-profit from Huesca that supports children in Guaricano (Dominican Republic). The previous Canva site blocked Google from indexing it and rendered everything with JavaScript. The new one is static HTML built with Astro and Tailwind, with a Sveltia CMS editing panel behind GitHub login so the association updates texts, photos and projects (each one a blog-style page) without touching code. Changes go through pull requests validated by GitHub Actions, photos are resized and compressed automatically on upload, fonts are self-hosted and there are no cookies. Deployed on Cloudflare Pages, scoring 97 on mobile and 100 on desktop in PageSpeed Insights, and 100 in SEO.
