Measurement strategy, business intelligence and custom dashboards. I help organizations turn scattered data into decisions they can trust.
End-to-end analytics — from setting up measurement to delivering dashboards your team will actually use.
Need to measure activities on your website or analyze already measured data? I prepare a complete measurement strategy and implement it end-to-end. GA4, GTM and server-side tagging.
How many stand-alone reports do you have? Let’s build centralized dashboards available everywhere — even in your pocket. Power BI, Looker Studio, Tableau.
CSV, XML, JSON, database — whatever data, I can connect and prepare custom reports either in Looker Studio or in a more advanced way in a BI platform.
Whether you need analytical knowledge for yourself or your team, let’s find the best format. We can sometimes meet at the Prague University of Economics and Business.
I am a Web & Data Analyst based in Czech Republic. I split my time between client projects and building data infrastructure that organizations can actually trust.

Professional, analytical, human approach. After 6 months of cooperation we did not hesitate to extend our contract.
