Hi there, I'm Artem 👋

🔹 Data Analyst | SQL Enthusiast | BI Tools Explorer

🚀 About Me

I'm Artem Liakh, a Junior Data Analyst passionate about uncovering hidden patterns in data and communicating insights in a clear and convincing way.

I enjoy transforming raw data into impactful visual stories and well-structured dashboards using BI tools. What drives me is the speed with which insights lead to action and how simplicity and clarity in visualization help decision-makers across business, science, and beyond.
