Hello there! My name is Jan Luca Siewert. I have a Master degree in Mechanical Engineering where I specialised on Computer Science in Engineering and Automation Technologies at the Ruhr University Bochum. Now, I work at the Chair for Digital Engineering and research on digitalisation and Industry 4.0 in general as well as Augmented Reality and AR Content Management for industrial applications.

I developed AR applications for nearly 10 years with different frameworks like Metaio and Vuforio. Now I mostly develop iOS applications with ARKit, with some In recent years, I also focused a lot on Product Lifecycle Management, the Internet of Things, and Data and Knowledge Management. I also frequently develop in Python, JavaScript, and run our backend server infrastructure through Docker. I enjoy learning and applying this knowledge above anything else. I probably spent more time configuring this website to my preferences over creation content. Because I think it is fun.
