Lume Courier
A three-portal courier and fulfilment platform we built and still operate — merchants book, admins price and settle, the support desk works tickets, and three courier APIs are driven end to end.
- Multi-tenant from the first commit — every query carries a merchant predicate; cross-tenant access is a test, not a hope
- Settlement invoicing — billing periods, proration, adjustments and a conservation invariant that must balance
- Per-merchant rate cards — negotiated pricing per weight band, stamped onto the order so an invoice can be defended later
- AI where it earns it — shipment narratives and address resolution — proposed to a human, never auto-applied
- Web Push written to the RFC — RFC 8291 encryption verified against the specification’s own published test vector
- Label and manifest generation — airway bills merged server-side, our brand stamped on every courier’s paperwork
- Continuous deployment — a gated deploy: the suite runs, and the tree is refused if it has not
- Operated, not delivered — we run it in production — the on-call is ours
