High-Volume Storefront Engine

Headless commerce architecture built to withstand 50k requests per second during peak product drops.

Architectural Highlights

• Distributed Lock Management: Redis-based lock mechanism preventing inventory over-allocation during concurrent checkouts.
• Edge Static Generation: Next.js ISR (Incremental Static Regeneration) ensuring product pages load instantly worldwide.
• Asynchronous Order Processing: Celery tasks processing payment webhooks in parallel worker queues.
