The problem

A members club needs more than a website: applications, invoicing and renewals, a member portal and a staff console, all sharing one source of truth, and it had to ship fast.

Key decisions

1. 01

   Double booking is impossible at the database level: each booking stores a time range, and an exclusion constraint per space and per member rejects overlaps, even when two requests arrive at once.

2. 02

   Every table starts locked. Members only see what’s published, staff do the writing, and a test proves the public site can read nothing sensitive and write nothing.

3. 03

   Invoicing runs through Hyfin with the club’s ledger as the authority: a webhook verifies and settles each payment, and a daily sweep raises renewals and catches anything the webhook missed. Emails go out through an outbox, so a failed send never loses a booking.

Outcome

Built solo in 14 days, from schema to invoicing: 270 commits, 12 design specs and 19 phase plans. A marketing site with the membership application, a member portal and a staff console, live and taking applications.
