Superstore Sales Report

The entire sales performance, including revenue and profit reports. Those reports can be segmented by category and region and find insights on daily/monthly/quarterly/yearly sales. Each chart works as a filter. By clicking, you can find segment-wise performance

Sales Performance

This is a sales performance dashboard for a ticketing platform. I built this by collecting data from three different sources, developing an ETL pipeline, and then making a visualization in Tableau. For the ETL development, I used Python.

120 Years of Olympic History

This is an animated visual demonstration of all Olympic games in Tableau. It has all of the host cities along with a map of all the winning countries. I also added a racing bar chart for the country rankings based on the total number of medals.

Google Search Trend Analysis for Bangladeshi Telcos

Bangladesh has three telco giants, and I have collected Google search behavioral data regarding these three operators and created this comparison dashboard. Click on the brand icons to see a brand-wise view.

Supply Chain Performance Dashboard

A telecom company needed a supply chain logistics and auction monthly dashboard for MoM performance monitoring. It needed to track PO, LC, and shipments on a regular basis so they used this dashboard to track all of their KPIs.

Excel-to-PowerPoint Automation

I automated a 60-page PowerPoint file (PPT) process. The process automatically generates a PPT file using the charts and data from over ten different Excel workbooks. Starting with the Excel file, we build a fixed format, and then the data is refreshed weekly using an SQL database. Then after running the VBA script, the PTT file is generated.
