Signal Iduna

Real-time coverage approval of a cost estimate (KVA) in health insurance as a customer journey and part of the digital transformation.
The customer takes a photo of the KVA in the app, which sends it to the server, which then calls OCR and domain data analysis and passes this data to the mainframe for evaluation.
The result is then delivered to the app via push notification.
The challenge in the complexity of the process itself was to convince the departments of this approach with tact.
From a technical standpoint, OCR was used directly during photo capture for the first time, allowing customers to receive qualified feedback while entering invoices and discarding unusable snaps immediately.

Summary

Passionate programmer, early Java developer, since 1995.

After almost 5 years as an employee, I started freelancing in July 2000. In numerous medium and large projects, I gained not only technical but also professional and political valuable experience. My solution proposals are gladly implemented, and challenges are tackled together.

I prefer MicroServices combined with MicroFrontends. Especially in large companies with different departments, this allows building silos and seamlessly integrating them into a website without making the architecture complicated. The technical openness of these powerful tools makes it possible to completely replace individual components and even implement them with new frameworks without affecting other components. This way, companies can gradually modernize their IT infrastructure over decades.

When it comes to testing, my main focus is on integration tests, e.g. with Selenium. MicroServices and MicroFrontends make this much easier and can be run quickly on developers' machines. Visual errors stand out immediately, so layout issues can be fixed quickly.

My passion for IT still beats like on the first day, even after all these years. This is shown, among other things, by the fact that I am currently evaluating different forms of AI training for use in chats as well as image processing in companies during my free time.
