An online store with wishlists, flash sales, recommendations, and scale

🎁

Collaborative Wishlists

Shareable wishlists with collaborators, followers, gift purchases, and price-drop alerts — backed by a dedicated caching layer.

How it works

✨

Intelligent Recommendations

Category- and tag-scored product recommendations plus semantic search with intent extraction and typo-tolerant matching.

How it works

⚡

Flash Sales

Time-boxed discounts with atomic, Redis-backed inventory reservations that prevent overselling under heavy concurrent load.

How it works

💳

Dual-Gateway Payments

Razorpay and PayU integrations with webhook verification, settlement reconciliation, and refund synchronization.

How it works

🛡️

Built to Survive Failure

Redis is a fail-open dependency everywhere — a degraded cache never takes the site down, and the load balancer never pulls a healthy node.

How it works

🚀

Scales to 20k Users

Cursor pagination, multi-layer caching, rate limiting, and 93 background jobs across Solid Queue and Sidekiq.

How it works

What this is

Ecommerce App is a full-featured online commerce platform built on Rails 8.1. It is not a tutorial project — it is a production-shaped system with real concerns: inventory that cannot oversell, payments that must reconcile, infrastructure that degrades gracefully instead of failing hard, and a test suite that guards every layer.

This site is a curated showcase of the engineering behind it. Start with the Introduction for the big picture, browse Features for what the platform does, or dig into Architecture & Scale for how it holds up under load.
