Hello, I'm

Vishnu Patil

Data Analyst β€” Power BI & SQL β€” Healthcare Domain

Turning messy data into decisions that actually matter.

The person behind the  data.

I'm a Data Analyst based in Hyderabad with a background in pharmacy β€” which sounds like an odd combination until you realise healthcare data is exactly where those worlds meet.

After completing my B.Pharm, I made a deliberate shift into analytics β€” teaching myself Power BI, SQL, Python, and Excel through real projects, not just tutorials. I believe the best way to learn data is to get your hands dirty with it.

Currently working as an Area Sales Executive at Renovate Biologicals while building out a full analytics portfolio β€” because if you want to transition into a field, you show your work.
