Tuncay-Sahin/README.md

Hi, I’m @Tuncay-Sahin.

I'm focused on Data Science and structured analytical thinking, with a growing foundation in Computer Science.

My work centers around Python for data analysis, econometrics, and time series modeling, with an emphasis on reproducible workflows and modular documentation systems.

Currently building portfolio-driven projects to strengthen my foundations in statistics, econometrics, and applied data science.

Open to collaborating on projects that value clarity, structure, and continuous technical improvement.

Iterating toward technical excellence — one version at a time.
