The surveyor

You reach the person who wrote it

Kavel exists because every Cloudflare project I started needed the same wiring, auth, payments, email and i18n, and doing it by hand each time was the tedious part. The storefront you are reading runs on the kit itself. When something breaks or you need something that is not there, your email comes to me, not to a support queue.
