Md Golam Sarwar

I am a data analyst specialising in operational efficiency, data transformation, and business intelligence. With a background managing logistics operations and supply chain workflows as a team lead, I dont just crunch numbers—I understand the real world business bottlenecks behind the data.

I help businesses replace manual, messy spreadsheets with automated reporting and clear visual dashboards.

My Core Expertise:

Microsoft Excel: Advanced data cleaning and automation using Power Query, complex formulas, and PivotTables.

SQL: Relational database management, querying, CTEs, JOINs, and window functions.

Power BI: DAX formulation, interactive dashboard design, and KPI tracking.

Recent Project Highlights:

Analysed a dataset of over 97,000 support tickets to identify workflow inefficiencies and optimise resolution times.

Conducted a data informed business strategy analysis for a retail client, evaluating customer purchasing behaviour and seasonal sales patterns to drive revenue.
