Back to original languageAbout Maximilian Samuel
As a Data Analyst with strong data engineering expertise, I support data projects end-to-end – from the data source through the pipeline to the finished dashboard. My focus is on turning complex, distributed data into reliable decision-making foundations.
Technically, I primarily work with Google Cloud (BigQuery, Dataflow, Pub/Sub), SQL, Python, and Looker Studio. I design and build scalable ETL/ELT processes including API integrations, automate recurring analyses, and set up clean, maintainable data architectures. This is complemented by statistical modeling and an economics background (focus on econometrics & controlling), so I understand not only the technology but also the underlying business question.
Through my experience in performance marketing, I know how reporting can turn into real recommendations for action.
I particularly enjoy supporting startups and smaller teams that don't yet have their own data structure – whether it's a one-off dashboard, pipeline setup, or ongoing analysis. I am currently certifying as a Google Cloud Professional Data Engineer.
