About.
Berlin, 2026Ongoing chapter

I translate between two languages — boardroom and Jupyter notebook — without losing too much in either direction.

Data scientist with four years at Accenture's Strategy & Consulting Global Network, delivering end-to-end ML and NLP solutions for Fortune 500 clients. Advanced from Analyst to Technical Lead in three years.

The work I'm proud of lives in the unglamorous middle of the stack: BERT/RoBERTa pipelines at 90%+ accuracy on retail data, ensemble recommendation systems combining collaborative filtering with propensity scoring, market-mix models with proper adstock and saturation. I delivered a €41M revenue opportunity through NLP-based categorization and geographic analysis across 350,000+ retail outlets, and won the firm-wide GenAI Hackathon in 2024.

Now in Berlin, learning German, occasionally Spanish and French, reading too many papers about graph-based retrieval.
