About Lorenz

Data Engineer and BI Consultant with over 7 years of experience at the intersection of consulting, data architecture, and reporting.
Focus: End-to-end data platforms – from integrating heterogeneous data sources and dimensional modeling to reporting and self-service BI systems that are actually used in daily operations.

From 7 years of consulting and M&A background in the German SME sector comes a clear understanding of which data drives decisions – and which merely fills reports.

Focus areas:
– Data modeling & ETL pipelines (SQL, Python)
– BI and reporting architecture with Power BI (semantic layer, star schema, RLS)
– Cloud fundamentals on AWS (Certified Cloud Practitioner, 2025)
– CRM and Salesforce integration, web scraping, data migration

Selected references:
– Board reporting for an international tax consulting firm
– Scientific analysis suite for the Doerner Institute of the Bavarian State Picture Collections
– Power BI maintenance for an international cruise line
– Salesforce migration and CRM integration for a medium-sized consulting group

Available for projects immediately, remote or in the Munich area.

⭐⭐⭐⭐⭐ Rating for Lorenz Huber The collaboration with Lorenz Huber is at the highest technical and structural level. He has designed a future-proof database solution for our company that has transformed our previous data structure, developed over many years, into a central, clearly structured data source. As a result, our data is now significantly clearer, faster to analyze, and efficiently usable even with large amounts of data. The foundation created for further integrations, such as the automated connection to our internal planning and analysis systems, is particularly valuable. The solution is also consistently scalable and allows us to easily map future growth. In addition to his high technical competence, I particularly appreciate his structured way of thinking, his reliability, and his understanding of entrepreneurial requirements. I can recommend collaborating with Lorenz without reservation!
