About Me
Who am I?
I’m a physics student with a love for data analysis and statistical exploration. Studying physics has
given me a strong foundation in analytical thinking, which I now apply to understanding and
interpreting data. With skills in Excel, Power BI, Python, and R, I enjoy working with data to
uncover trends and make sense of complex information.
To me, data analysis is about more than just numbers; it’s a way to solve real problems and make
decisions clearer. Whether through visualizations or careful statistical insights, I’m passionate
about revealing the stories data has to tell.
Education
- Studied Physics at the University of Dhaka in Bangladesh.
- Studying Physics at Marmara University with the prestigious full-ride Türkiye Bursları (Turkish Scholarships).

Nazmul was a fantastic data analysis freelancer who went above and beyond expectations. He quickly grasped our business needs and identified key performance indicators (KPIs) like customer acquisition cost and churn rate. Using his Excel mastery, he built a dynamic dashboard that automatically updates with new data, saving us hours of manual work....
