Sourcigo
Import, customs and sales platform for China importers
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. It is a pnpm and Turborepo monorepo, built with a teammate: a NestJS API over PostgreSQL with Prisma (49 models, more than sixty migrations), a React dashboard on TanStack Query and Table, and a Flutter companion app. My work concentrated on the pricing calculator that spreads container charges across products by value share, the per-rate modes and final surcharge step in the customs-duty cascade, and the Excel exports — embedded product photos, server-side pricing and simulation exports, and columns blanked for roles that cannot see them.
