About
I build the data infrastructure teams depend on.
I build the data infrastructure that teams depend on for real decisions. At a Berlin-based fintech startup, I designed the entire data platform from scratch — a medallion architecture processing production data through four transformation layers into business-ready analytics.
My work spans the full data lifecycle: extraction pipelines, dimensional modeling with dbt, automated financial reporting for banking partners, and data quality frameworks that catch problems before they reach stakeholders.
With a freshly completed MSc in Data Science and 4+ years of hands-on experience across freelance, enterprise, and startup environments, I bridge the gap between engineering rigor and statistical modeling.
