About EdgeCart Sync
High-performance flash-sale commerce architecture built with Go, Next.js, and Re
High-performance full-stack e-commerce architecture called "EdgeCart Sync" built from scratch, optimized for heavy concurrency. Recreating industry-standard architectural decisions for handling high-concurrency event-driven checkouts. Technical Architecture & Highlights: • Frontend: Next.js (App Router) + TailwindCSS, utilizing Optimistic UI state updates to update cart states under <50ms for the ultimate user experience. • Backend: Pure Go (Golang) server optimized for maximum throughput and ultra-low latency order ingestion. • Message Broker: Redis Streams implementation to completely decouple write-heavy checkout operations. • Concurrency Control: Robust Optimistic Locking implemented inside PostgreSQL to strictly avoid negative inventory balances or overselling during high-concurrency race conditions. • Security: Built-in Token Bucket Rate Limiting middleware to block automated scalper bots right at the API gateway. What's included in the private repository: • Production-grade frontend and backend source code. • Pre-configured k6 load testing simulation script (targeted at 5,000 requests/second). • Automated database inventory verification scripts. • Full architecture diagram, documentation, and operational notes.
