The Master Data Dashboard for Buying Prices is a web application developed for one of the biggest retailers. The solution was built to simplify the interaction between suppliers and category managers when negotiating over prices and ensure the data quality at the same time.

The solution automates error-prone workflow processes where previously people had to interact directly with databases, and had to sift through spreadsheets, and e-mails.


The application is specifically designed for continuous delivery & deployment. All its services are stateless, and can be replicated – scaling the app to changing demands is simple. Automated integration tests validate each change to the code base. Running in a corporate environment the solution has to interface with several legacy systems, and interact with the existing infrastructure. It needs to be resilient to failures of systems outside its own scope. Last but not least its software architecture and code allow for an efficient maintenance over a long life cycle.


The backend consists of micro services implemented with Java8/Spring-Boot, and Node.js. It persists data to a Cassandra DB, and uses SOLR for indexing. All services are dockerized, and run in a Kubernetes cluster at the client site. The UI is based on React/Redux.
