Hey, I'm Giriharan!
I make data less boring.

  • 📊 Data Scientist
  • ⚡ Power BI Data Analyst
  • 🛠️ Backend Developer

I take big piles of messy data and turn them into dashboards people actually enjoy looking at. Part data nerd, part backend tinkerer, fully caffeinated. Microsoft-certified in Power BI, and always up for a fun data problem. ✨

About

A little about me 👀

So here's the deal: I love the whole journey of data — grabbing it, cleaning up the mess, poking at it with some machine learning, and finally turning it into dashboards that make people go "ohhh, now I get it."

When I'm not living in Power BI, I'm on the backend building the APIs and pipelines that keep everything running. Clean data models, reproducible work, and dashboards that answer real questions — that's my happy place. 🙌
