Data Engineer & ML/AI Practitioner, PhD — production ELT pipelines, applied ML systems, and a research background in computational mathematics.
I design and build data systems that hold up in production — layered ELT pipelines, cloud data warehouses, and applied ML/AI systems — with the same rigor I spent five years applying to peer-reviewed numerical research.
- 🔭 Building cloud-native ELT pipelines and MLOps systems (GCP · dbt-style layered warehouses · Prefect · MLflow)
- 🤖 Shipping RAG and LLM-powered applications grounded in real data sources, not model guesswork
- 🎓 Lecturing in Data Analytics & Machine Learning (Berlin School of Business & Innovation)
- 📄 PhD in Computational Mathematics (Quasi-Monte Carlo methods) · 5 peer-reviewed publications · Google Scholar · ORCID
