Synk Food: B2C and B2B online store

Challenge

Synk Food sells gourmet Korean products to retail and wholesale customers. It needed one store for both, without letting anyone sign up as a wholesaler, with payments that never left orders half-done, a catalog and blog in Spanish and English, and heavy tasks, such as invoices and emails, that did not slow down browsing.

Solution

• Service-layer architecture in Django, with custom managers that keep business logic out of the views and avoid repeated queries.
• Team-approved wholesale accounts: nobody can assign themselves that account type; it is requested through a form and granted after review.
• Stripe payments confirmed by webhooks.
• Celery in the background to generate PDF invoices with WeasyPrint and send emails.
• “Bought together” recommendations computed in Redis.
• A catalog in two languages with automatic DeepL translation and a SHA-256 fingerprint cache, so the same text is never translated twice.
• Google sign-in and a second factor (TOTP).
• Continuous integration with GitHub Actions: Ruff linting, tests and CodeQL security analysis.

Outcome

Synk Food has a store that serves retail and wholesale from one codebase, keeps heavy tasks out of the user’s request and is checked automatically on every change.
