xitee? What are we doing?

Our customers are primarily from three main sectors.

At Finance&Energy, we are active in development for the leading European financial exchanges. The finance sector is an area we started in and have been in for over 15 years, so we have rich experience and can afford to go into bigger and more complex projects. For example, we are currently developing a brand new greenfield trading system that has an advanced technology architecture and processes tens of thousands of events per second.

In Health, we are working with leading German health insurance companies. We are currently developing a system for managing the insured's account in a microservice architecture for one of the leading German health insurance companies. For example, we are also developing a system for the organization of assistance services for handicapped insureds throughout Germany. Another hot trend in this area is digital aids paid for by health insurance, for example, the Apple watch app we are developing, based on the use of health data from the watch, which allows cardiologists to monitor the ECG of their patients.

The third sector is Digital Business. We are keeping up, and have opened up further opportunities in this growing area, in the development of cloud-based solutions. A current example is building a platform for financing development projects, running on Microsoft cloud services (Azure).
