The marketing site, gated member hub and internal lead CRM behind playfundwin.com, where UK clubs, schools and charities run 50/50 draws, raffles and 100 clubs. 62 entities and 59 Deno functions in one app, including a nightly content agent and an SEO crawler that writes its own runs, pages and issues back into the database. The pages are the easy half. Base44 serves every backend function anonymously and leaves any entity without an explicit rule world-readable, drafts included, so the access control has to be written by hand into each function and each schema.

What makes it work

  • The admin-or-workflow gate is inlined verbatim into 27 functions, timing-safe compare and all; the 9 public ones each carry a PUBLIC_BY_DESIGN comment saying why
  • GdprAuditLog holds a SHA-256 of the email, never the email, and the purge writes its audit row before the auth record goes so the trail outlives the user
  • Any function that fetches a caller-supplied URL inlines safeFetch: manual redirects, three hops, private IPv4 and link-local refused, 5 MB streamed cap

How it gets made

Nine parts, in the same order, every time.

Every build on this site comes out of the same structure, whether it is a game, a ledger or a suite of tools. The method is published in full, and so are the prompts I am allowed to publish.
