About

I’m a software developer from Germany and a Master student in Business Innovation & Technology at Hochschule Bielefeld (HSBI). Most of my open-source work sits on Bitcoin’s network layer: DNS seeders, crawlers, ASmap data, and the question of how you measure decentralization when every data source counts a different network.

Before Bitcoin took over, I built RAG and knowledge-graph systems in industry and at university. That work still shows up here occasionally.
