Hey, I'm Constantin.

I'm interested in building products. I discovered order books when I was 15 and have since built market related products, such as an NBBO, an RFQ maker, and finding niche binary markets. I'm interested in venture investing as well.

In my free time I enjoy playing tennis & golf, watching football and exploring the mountains.
