Summary

I am a Microsoft certified cloud developer with a strong focus on data analytics. During my 10 years of experience, I have developed a strong understanding of relational and unstructured data using tools like SQL, C#, Python or Spark.

I conducted numerous data analytics projects that laid out the groundwork for revealing game-changing insights for my clients, including well-known enterprises such as DHL, VW and Telekom.

I also gained a lot of experience in creating complex Power BI and Tableau dashboards that turned plain data into meaningful information.

I am currently developing an open-source BI scheduling tool named Stage Director.
