About me
Analytical thinking.
Business impact.
A portfolio concept for a data professional who combines business understanding with modern analytics and visualization.
I’m a data analyst and Power BI developer focused on transforming raw, messy data into reliable reporting systems and decision-ready insights.
My work spans data preparation, semantic modeling, DAX, Power Query, dashboard design, automation, and exploratory analysis using Python and Excel.
I care about more than making dashboards look good. A strong analytical solution should answer the right business question, make assumptions visible, and help stakeholders act with confidence.

Nazmul was a fantastic data analysis freelancer who went above and beyond expectations. I highly recommend Nazmul to anyone seeking a skilled, proactive, and communicative data analyst.

Nazmul brought a creative and efficient solution to calculating and distributing monthly commission statements from 4 different systems. Took the process from 1.5 days of manual work to less than an hour. Able to pay commissions 5 days faster helps sales team focus on sales and increases trust in the commission calculations.
