Behind every dashboard, automation, and data workflow, the goal is the same: make complex information easier to understand and act on.

I start with the actual business need, then shape the analysis, automation, or data workflow around it.

The result is a solution designed for clarity, reliability, and practical use — not just technical output.

ABOUT ME

Python, data, and thoughtful problem-solving.

I build practical Python solutions that turn data and repetitive processes into clear, reliable systems.

My work spans business analytics, automation, web scraping, API integration, data processing, and reporting. I focus on building solutions that make information easier to understand, use, and act on.

Alongside my work in Python and data, I study Psychology at Akdeniz University, where my academic work includes statistics, SPSS, research methods, and behavioral analysis. This background strengthens the way I approach data — combining technical analysis with an understanding of patterns, context, and human behavior.

I value clarity, reliability, and thoughtful problem-solving, and I approach each project around the needs behind the data rather than applying one-size-fits-all solutions.
