01

Problem

Sales teams researching small businesses in Gujarat were stitching leads together by hand from maps, registries and spreadsheets.

02

What I built

I built a lead research and qualification system covering 35 Gujarat cities, with a 6-step discovery wizard on the official Google Places API, an address-verification guard on every write path and 7-level deduplication that sends uncertain matches to manual merge.

A configurable scoring engine explains every point. It never asserts turnover without evidence and never treats a missing GST record as proof of anything. Results export to a formatted multi-sheet Excel workbook.

The backend is FastAPI with SQLAlchemy on SQLite, with background jobs and 154 tests. The frontend is React, Vite and Tailwind with dashboard charts and a CSV and XLSX import wizard.
