01 / Problem

What wasn't working.

66 locks across 13 sites, each managed in a vendor phone app. Staff codes never got removed. Guest codes were set by hand.

02 / Approach

What I built.

  1. 01

    One state document per lock and person, worked by a background tick that talks to the lock vendor's cloud API.

  2. 02

    Rate-limited to 24 of the vendor's 30 requests a minute, so the fleet push never gets throttled.

  3. 03

    Self-service access requests, approved by email.

  4. 04

    The booking and crew apps draw their PINs from here. One source of truth for who can open what.
