Besaiem — Multi-vendor Marketplace

Buyers and sellers need one marketplace that stays fast under unpredictable, bursty traffic — without a big-platform budget behind it.

Built the complete Besaiem marketplace — a multi-vendor Buy & Sell platform — across two deliberate tech stacks. The backend API is written in Go with the Gin framework for its concurrency model and low-overhead request handling. The frontend is built with Next.js and TypeScript for fast, server-rendered product browsing and SEO. Each layer is independently deployable with a clean REST contract between them.

Chose Go for the backend API to leverage its goroutine concurrency model for a marketplace with unpredictable, bursty traffic patterns.

Kept the frontend and backend as two separate deployable units with a clean REST boundary — no shared runtime coupling.

Designed the vendor-to-product ownership model so the marketplace scales horizontally with more sellers without schema changes.

Used Next.js SSR and static generation for product listing pages so pages load fast and remain indexable without a separate CDN layer.
