Our own system for running online stores. It currently powers the Chulas store.

  • Custom delivery pricing on a hexagonal grid: distance-based zones priced by fuel, mileage and a street factor, with a free-delivery radius and a zone map for customers
  • Catalog synced with two wholesale suppliers, fault tolerant
  • WhatsApp and email via the outbox pattern, inside the order transaction
  • CI/CD: tests, Docker image and deploy on every merge
