Business problems, broken down into decisions that actually matter.
I use simple numbers, clear assumptions, and practical trade-offs to understand what a business should do next — not just what the spreadsheet says.
Case studies
Each case starts with a simple business question and ends with a recommendation, the logic behind it, and the numbers that support it.
Cutting Chai: Finding the right price
How far can a small tea shop increase price before the volume loss starts hurting total contribution?
GharKaKhana: Direct orders vs platforms
Should a food business push customers away from aggregators, or improve the economics of both channels?
Circle of Crust: Menu and platform economics
Testing add-ons and platform price changes to improve monthly operating profit without overreaching on demand.
From question to recommendation
I try to keep the model only as complex as the decision requires.

I work at the intersection of business analysis, data analytics, automation and operations. These case studies are my way of practising structured business thinking with real-world style problems.
Clear assumptions, spreadsheet-backed analysis, business trade-offs, and recommendations written for decision-makers rather than just analysts.
