E-Commerce Platform Migration to Cloud-Native

ShopEasy had outgrown the monolith that built their business. Every sale season was a gamble on whether the single application server would survive the traffic, and a change to the checkout meant redeploying the entire store. The platform was not broken; it was simply unable to grow at the pace the business now needed. We migrated incrementally rather than rewriting from scratch - the strangler approach, peeling off one capability at a time behind a stable API so the live store never stopped selling. Catalog, cart, and checkout each became services that scale on their own, containerized and orchestrated so capacity follows demand instead of being provisioned for the worst case all year round. The result was a platform that absorbs seasonal spikes by scaling the services that actually feel them, while the rest stay lean. Deploys went from a coordinated event to a routine, several-times-a-day non-event, and the infrastructure bill dropped because ShopEasy stopped paying year-round for peak-day capacity.
