E-commerce API Platform

Unified 4 storefronts behind one API with 99.9% uptime.

Problem

Four brand sites each had fragile, duplicated backends. Inventory sync failed often, and every feature change meant four deployments.

Approach

Designed a single NestJS API with Redis caching, webhook-driven inventory updates, and role-based admin access. Migrated brands one at a time with zero-downtime cutovers - backend engineering with a full-stack mindset for storefront clients.

Outcome

One API now serves all storefronts. Inventory sync errors dropped to near-zero and the team ships features once instead of four times.

The API docs alone saved our frontend team weeks. Rock-solid Node.js delivery.
