Rapidly modernizing a business-critical legacy application for 850 stores

Hunkemöller needed to modernize an advanced legacy application, originally developed in 2011. Using Rappit Developer, the application was rapidly rebuilt and extended on Google Cloud. This resulted in a modern, future-proof solution that provides a consistent retail experience for 850 international stores, with a Return On Investment of 1 year.

Their challenges

  • A business-critical application: The “Store Information Database” is the single application managing all store information, displays and in-store campaigns. The app is integrated to backend systems like SAP, and is also used by external users with integrations to e.g. Google Maps for each store’s location and opening hours.
  • Legacy technology: Underlying Drupal 7 technology of existing custom developed solution reached end-of-life, posing risks to continuity and security.


  • No off-the-shelf solution options: Desired functionality is not available in existing SAAS solutions. Hence, the application needs to be swiftly rebuilt on modern technology, with additional features to make it future-proof.
  • Low value add of low-code platforms: Lack of flexibility around required customizations & UI, platform vendor lock-in, and costly run-time licenses.
  • Preference for solution on Google Cloud, as Hunkemöller is a GCP user.

Our solutions

  • Development of a cloud-native application including new functionality, on Google Cloud (GCP). Around 80% of code generated with Rappit application development accelerator. Remaining business logic added manually by developers.
  • Iterative prototyping of real app screens with early feedback from key users to refine the requirements. This prevents risks popping up at a later stage.
  • Functional modules developed include sites, contacts, fixtures, campaigns.


  • Modern and intuitive user interface, matching Hunkemöller’s branding.
  • New, time-saving functionality included, such as a user friendly way to mass-update store records via “drag and drop” and the ability to update existing data in bulk via spreadsheet upload and import.
  • Optimized for Google Cloud, with application data automatically synced to BigQuery for data analytics.
  • Seamless integrations with back-end systems, including SSO with Okta.
