Basic idea

The QS-Monitor is a tool for the automated calculation of data quality, designed to provide a foundation for improving data quality.

Mainzer Stadtwerke AG supplies Mainz and the surrounding area with electricity, gas, water, heat, and public transportation. It supplies drinking water to around 265,000 people, provides electricity to 550,000 citizens, and ensures mobility with trams and buses—committed, reliable, and regional. To ensure that all these processes run smoothly, Mainzer Stadtwerke works internally every day with large and complex amounts of data that enable precise planning, control, and supply.

THE WHOLE STORY

After five years of use and further development, the current system had reached its technical and operational limits - particularly in terms of maintainability, scalability, and performance. The integration of new class specifications and the connection of additional systems are also increasingly complex. The aim was therefore to transform and redevelop the QS-Monitor based on a future-proof system architecture.

CHALLENGES

This project combined numerous technical requirements with a high demand for user-friendliness and performance. The intention was to present a large amount of complex data and calculation logic in a clear and intuitive interface - without compromising on speed.

A simulation mode was intended to make users' day-to-day work more efficient, while differentiated role and rights management ensured maximum security. The integration of large Excel files and a deep connection to existing SharePoint structures was particularly challenging.

In addition, the solution had to be integrated into an on-premises Kubernetes infrastructure - while adhering to a very ambitious schedule.

RESULT

The result of this project was a modernized, scalable and maintainable system that works efficiently, is expandable and enables the integration of additional data sources - as a stable basis for sustainable data quality assurance.

RESUME

Thanks to a powerful technology stack (Go, React, Kubernetes) that was carefully evaluated in advance, a stable and future-proof solution was implemented. The close, constructive collaboration with the customer was a key success factor - characterized by trust, openness and a clear vision.

The result: a high-performance application with real added value in day-to-day work - and a satisfied customer who was won over by efficiency, transparency and user-friendliness.
