System Transformation – How to build a new platform

Conference Stage 1

Interhyp Gruppe was founded in 1999 and is the market leader in the field of private real estate mortgages. With the help of over 150 colleagues in the digital sector, they are working on developing a completely new platform in the field of real estate financing called „home“. In this talk, Jelena and Benjamin will share their insights on the transformation of a grown monolithic system into a modern microservice architecture.

How do you truly build a platform that caters to all user groups?
How do you digitize processes in which millions of paper sheets are sent via courier and processed by over 500 lenders each year?

They will provide you with an overview of the development of Interhyp’s overarching architecture and a deep dive into what needs to be considered in the work of an individual squad. How can you, regardless of your role, support the journey towards platform or system transformation, and why is this ultimately relevant to everyone in the company?
