Senior🎓
Top SchoolDavid Jahn is a Microsoft-certified Power BI consultant and data engineer with over three decades of software development experience and 11 years focused on BI and cloud analytics. He designs and delivers performant Power BI reports and Azure data pipelines—leveraging PySpark, Synapse, ADF, Azure SQL and Data Explorer—to turn complex operational data into timely sales and forecasting insights. At Chevron he led the build of a real-time, big-data cloud system for transaction visibility, and more recently he’s driven sales-forecasting BI at Toyoda Gosei Americas. David bridges deep legacy systems knowledge (mainframe to SAP migrations) with modern cloud architectures, frequently pre-aggregating data in Synapse to dramatically improve report performance. Based in Florida, he’s equally comfortable guiding small teams as he is hands-on coding and optimizing ETL for production dashboards.
