How it happened

01
The Beginning

One storefront, then five, then chaos

The client was launching a new storefront for every brand they picked up, each on its own codebase. Every bug fix had to be repeated five times, and nobody could tell which store's code was actually up to date.

02
The Challenge

One codebase, real traffic, zero downtime tolerance

Consolidating into one multi-tenant platform meant every module — cart, checkout, catalog — had to stay cleanly separated per tenant while sharing infrastructure, and the checkout flow had to hold up under real sale-day traffic, not staging-environment traffic.

03
How We Solved It

Modular by domain, cached by design

I split the platform into clean domain boundaries so each store's catalog, pricing and cart logic stayed independent, wired Stripe for checkout, and built a caching strategy around the product pages specifically — the pages that actually get hammered on a sale day.

04
The Result

Five stores, one team, no more duplicated fixes

New brands now launch on the same platform in days instead of weeks, every bug fix ships once and applies everywhere, and the checkout has held up through every sale event since launch.
