# About — Arda Oğulcan Üzer

> Data Scientist & Business Analyst in Warsaw, Poland. Transforming complex data into meaningful insights through analytics, statistical modeling, and machine learning.

## Engineering rigor, applied to questions that matter.

I’m a data scientist and business analyst with a foundation in computer engineering. My work sits where rigorous analysis meets practical decisions: exploring data carefully, building statistical and machine learning models, and explaining what the results mean for the people who need to act on them.

Engineering taught me to break problems down, question assumptions and build solutions that are reproducible. I bring the same discipline to analytics — from data cleaning and feature engineering to model selection, validation and interpretation.

I’m currently completing my MSc in Data Science & Business Analytics at the University of Warsaw, with a particular interest in statistical modeling, unsupervised learning and machine learning applied to real business questions.

- **Focus:** Statistical modeling · Machine learning · Business analytics

### How I approach a problem

1. **Frame** — Translate a business question into a measurable analytical problem with explicit assumptions.
2. **Explore** — Clean, profile and visualize the data to understand its structure, quality and limits.
3. **Model** — Apply statistical and machine learning methods, engineer features and validate the results.
4. **Communicate** — Turn findings into clear visuals and recommendations that stakeholders can act on.
