Full Stack Developer / Quant

Summary

From a first principle way of thinking I construct trading systems and digital applications. From zero to one. My clients are founders, traders, and companies who need trustworthy production-ready software — not proposals.

I work with people who value execution over process. If you need sophisticated technical infrastructure built and shipped, let's get in contact!
