Sourcigo

Import, customs and sales platform for China importers

sourcigo.yoptn.shop

Sourcigo is a multi-tenant platform for importers who source goods in China and sell them in local markets, covering suppliers, containers, customs duties, stock and point-of-sale. I built it as a pnpm and Turborepo monorepo: a NestJS API over PostgreSQL with Prisma (46 models, 60 migrations) laid out in hexagonal layers, a React dashboard on TanStack Query and Table, and a Flutter companion app. My work concentrated on the compounding customs-duty engine, the pricing calculator that spreads container charges across products by value share, and Excel exports that embed product photos.
