Portfolio Project for Data Analyst Jobs | End-to-End Sales Analysis Explained in Tamil

---

A complete portfolio project for data analyst jobs. This is an end-to-end Sales Analysis of an auto-parts business, from raw data to the insights and KPI dashboards that leadership actually uses.

You'll see how a real analyst thinks: start with a business problem, find the answer in the data, and turn it into a recommendation. By the end you'll have a resume-ready project for GitHub and LinkedIn, and you'll know how to explain it in a data analyst interview.

🔥 22 business insights we uncover, for example:
• Why the Dealer channel outperforms Online and Retail by about 15x
• How much revenue is lost to cancellations (4%) and discounts (8%)
• Which parts generate 80% of revenue
• Which regions and warehouses have the most delays and returns
• How to move customers from Intermediate to Loyal
