Freelancer profile translated to English.

Description

I help companies turn their data into clear decisions. As a freelance data analyst, I develop customized dashboards, automate data analysis, and build SQL databases so that you and your team no longer have to sit for hours in Excel, but can see what's important at a glance.

What I bring:

Several years of experience in Python, SQL, and data analysis. I have analyzed processes, built databases, and developed dashboards that are used daily.

What you get from me:

Clean, understandable results, no unnecessary tech jargon. I quickly get to grips with new industries and deliver pragmatic solutions that really work.

Typical projects: Reporting dashboards, database construction, process analysis, automation of analyses.
