🌟 Hey, welcome to my GitHub!

So glad you dropped by 👋

I’m someone who enjoys working with data, learning through real projects, and turning confusion into clarity (one SQL query or Power BI visual at a time).

Here on my GitHub, you’ll find:

  • 📊 Power BI, Tableau, and Excel dashboards that tell a data-driven sales story
  • 🏗️ A SQL data warehouse project built with Medallion Architecture
  • 🔍 An SQL-based exploratory analysis uncovering customer and product trends

This space is kind of like my learning journal, portfolio, and playground - all rolled into one.

Whether you’re here to learn, collaborate, or just curious - thanks for stopping by!

Let’s grow together 🚀
