Data & Analytics
Engineer.

I build data systems that scale — reliable pipelines on Snowflake, clean dbt models, and semantic layers teams trust. Now extending that into applied GenAI: RAG systems, rigorously evaluated.

About

Turning raw data into decisions.

I'm a Data & Analytics Engineer working across the modern data stack — from raw ingestion to business-ready models. My day-to-day is designing dimensional data models, building tested dbt transformations on Snowflake, and shipping analytics that managers actually use.

My differentiator is connecting that foundation to trustworthy AI. My MSc thesis tackles uncertainty calibration in retrieval-augmented LLMs — whether a model's confidence can actually be trusted for risk-sensitive decisions, and how embedding quality shapes that. I care about AI that's grounded, measured, and honest about what it doesn't know — not just demoed.

Currently based in Germany and open to Data Engineering, Analytics Engineering, and AI Engineer roles across Europe.
