Rahul Biswas —
I read spreadsheets
for a living.

Civil-engineering graduate turned data person. I build Excel dashboards that update themselves and write SQL that answers the next question before you ask it.

About

From site plans to spreadsheets.

I trained as a civil engineer — a B.Tech and a diploma spent measuring, planning, and problem-solving on paper. Somewhere along the way I got more curious about the numbers behind a project than the structure itself, and started teaching myself Excel, then SQL, then how to make both explain a story clearly.

These days that shows up as dashboards that rebuild themselves from raw data, and queries that go from "how many orders" to "which product actually drives revenue." I'm currently a Customer Executive at Startek, handling 50+ conversations a day — which has been its own crash course in staying calm, working fast, and reading what a CRM is actually telling you.
