A quote and ordering site for Top Papier, a print shop in Tizi-Ouzou. Clients upload their files, books first, and get a price straight away: a worker reads every page and measures its size and ink coverage, then the pricing engine applies the shop's cost tables and options. The shop manages its catalog, prices, pages and orders from an admin area. The site is in French, Arabic (right-to-left) and English.

How it's built
- Next.js front end and a NestJS API in strict TypeScript, with Prisma and PostgreSQL
- A BullMQ worker checks each upload by its content, converts Word files with Gotenberg and analyses pages with PDFium
- Ink coverage measured by Ghostscript in its own small service
- Files stored in SeaweedFS, an S3-compatible store hosted with the app
- Runs in Docker behind Caddy, with tested backups and restore, monitoring, and release and rollback scripts
- 118 unit and 96 end-to-end backend tests, plus Playwright journeys in the browser
