A multi-vendor marketplace
built as a production-grade reference

A reference build of a multi-vendor marketplace: users with email verification and TOTP 2FA, products with category trees, variants and full-text search, carts with multi-seller sub-orders and coupons, Stripe and crypto payments with refunds and platform commission, a seller cabinet with verification, an admin panel, JWT RS256 with refresh in httpOnly cookies, rate limiting, security headers and idempotency. Plus a geo-based Telegram shop prototype with two bots on one database.

What it covers

Everything a marketplace needs and most MVPs skip: verified accounts with 2FA, a seller onboarding and verification flow, sub-orders per seller inside one cart, refunds, commission, idempotent payments, object storage for media, background jobs, and a hardened auth layer. A separate prototype explores a Telegram shop organised by country and city with a customer bot and an admin bot sharing one database and crypto payments with polling.

These are reference builds we reuse in client work, listed so the full range is visible.
