About Me
Hi! I'm a Senior Data Engineer based in Berlin.
I specialize in building and managing scalable data infrastructure, with a strong background in ETL workflows, cloud platforms (AWS, Azure, GCP), and big data technologies like Spark and Kafka.
I thrive on transforming complex, raw data into structured, actionable insights and enjoy designing robust systems that power analytics and data science.
When I'm not designing data systems, here's what I enjoy:
