Jiří Mařík
Web & Data Analyst

Let’s exhaust
your business data.

Measurement strategy, business intelligence and custom dashboards. I help organizations turn scattered data into decisions they can trust.

— Services

Four ways
I make data work for you.

End-to-end analytics — from setting up measurement to delivering dashboards your team will actually use.

01

Web measurement implementation

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.

02

Business intelligence

How many stand-alone reports do you have? Let’s build centralized dashboards available everywhere — even in your pocket. Power BI, Looker Studio, Tableau.

03

Custom solutions and reports

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.

04

Trainings and workshops

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.

— About

12+ years turning data into decisions.

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.

My approach is pragmatic — not the biggest stack, the most expensive tool or the fanciest dashboard. The right one. The one that answers the question your business is asking right now.
