Community Marketplace (Next.js, Stripe, PostgreSQL, Elasticsearch, Redis) overview

A peer-to-peer community marketplace where users list, discover, and transact on goods or services with escrow-based payment protection. Next.js powers the storefront with server-side rendering for product listing SEO and dynamic client-side filtering. Stripe Connect handles multi-party payments with split disbursements to sellers and platform fee collection. PostgreSQL stores listings, user profiles, reviews, and transaction records with full-text search for simple queries. Elasticsearch provides advanced product search with faceted navigation, geo-proximity filtering, and personalized recommendations. Redis caches search results, user sessions, and real-time listing availability. The tradeoff is managing payment disputes, seller verification, and maintaining search index freshness as listings change frequently.
