Rebuild of a language school website with a lean file-based CMS – the school manages images, courses, prices and contact details on its own, without a database.

Starting point
Rebuild of a WordPress website for a language school. The school needed to manage courses, prices and images on its own – without a database and without the running costs of a heavy CMS.
What I built
Admin for images, prices, course packages, course list and contact details
Contact and referral forms as server-side endpoints
FAQ, learner testimonials and a location section
Technical details
Astro 7 with on-demand rendering and a 60-second CDN cache
File-based CMS in Vercel Blob: private store for content, public store for media, access via OIDC instead of a static token
Migrated from Supabase Storage to Vercel Blob
Writes are safe under concurrency through ETag checks
Admin endpoints only through a shared wrapper – a test enforces it
Content Security Policy with a script hash instead of unsafe-inline
CSS fallbacks for older Safari versions on the iPad
