Who am I?

Aspiring Data Analyst

My name is Paweł, and I work remotely as a freelance Data Analyst. I combine a strong background in customer service with a growing technical skill set to turn raw data into clear, actionable insights. Years of working directly with people taught me to listen analytically, understand context quickly, and identify the real problem behind the initial question — an ability that now strengthens my work with data.

I focus on reliability, clarity, and business impact. Through hands‑on projects in SQL, Excel, Power Query, Python basics, and data visualization, I’m building a practical, business‑oriented analytical toolkit. I enjoy bringing structure to messy data, simplifying complexity, and helping teams make confident, data‑driven decisions.
