All writing →- Everything is a BlobHow I think about blob storage: one immutable primitive, a registry table, presigned URLs, and foreign keys as the garbage collector.
- Building mysayo.comHow I built this site. A static Astro front-end, a React Compiler island, and a Cloudflare-only stack managed entirely in Terraform, with secrets that never touch the repo.
