Hello, my name is Christoph, I`am a software developer and I like to build and innovate solutions for the API ecosystem using type-safe/oop languages like PHP, TypeScript and Java.

I have started several open source projects like Fusio, a popular open source API management system or PSX a framework and set of components dedicated to build modern API solutions. I`am also the author of the TypeAPI and TypeSchema specification which provides a new way to describe REST APIs in a type-safe way.

Please take a look at my website chrisk.app to get an overview about all my projects. I`am working as team lead software developer at Artemeon where we build RegTech solutions for the financial and insurance sector.
