Back to original languageAbout Stefan
Marketing Intelligence Specialist | Data Analyst | Automation Expert
Hi, I'm Stefan. I help companies, service providers, and agencies to automate their data analysis in online marketing & sales and to sustainably improve their results.
With me, you get more control over all your online marketing activities, use budgets more efficiently, save time, and thus improve your results. I do this by getting to know your business precisely and then automating all data flows. With my help, my dashboards, and my automations, you get real decision support in everyday life!
My motto is “Work smarter, not harder.”: From my time as an Online Marketing Manager, I know that there is often little room for data analysis in everyday marketing. Therefore, I find it important to create free working time through clever automations. This works best for recurring and unpleasant routine tasks, such as creating reports or budget checks.
Tools and skills: BigQuery, Google Cloud, SQL, Python, Google Apps Script, Make.com, Zapier, Looker Studio, PowerBI, PowerAutomate, etc.
