Coupon platform

MediaMarktSaturn Retail Group (Ceconomy AG)

2020–23

A three-year engagement, from the first line of code to handover

Workstreams: coupon management tool and headless CMS integration

2023

Handed over to internal teams; the tool keeps running in the group without alm

Challenge

Every campaign a ticket

At one of the largest online presences in European consumer electronics, every marketing campaign and every couponing program ended up as a ticket in the developer backlog.

Marketing works on its own

An internal tool that lets marketing plan, create and end campaigns itself, plus engineering support for the group-wide move to a headless CMS.

What changed

Before

Marketing idea
Ticket
Developer backlog
Built by engineering
Campaign live

Every change ties up engineering capacity.

After

Marketing
Coupon dashboard
GraphQL API
Microservices
Campaign live

Marketing plans, launches and ends campaigns itself, without a detour through the backlog.

Solution

Coupon Management Service

Web dashboard for internal teams

Planning, creating and ending coupons and promotions. React and MUI, GraphQL API, microservice backend.

End-to-end tests with Cypress

Solid test coverage and CI setup: the precondition for the tool to stay maintainable without alm after handover.

Handover to internal teams

Documentation and knowledge transfer, so the group's teams can carry the tool forward on their own.

Headless CMS integration

Engineering guidance

Support for the transition from a monolithic to a decoupled content architecture.

Frontend integration

Concrete implementation work on connecting the Contentful-based headless CMS stack.

Result

Handed over and still running.

The coupon tool was handed over to the internal teams in 2023 and keeps running in the group without alm. That was possible because the codebase was designed for handover from day one. On the CMS side, alm's work became part of the group's headless architecture.
