# Mayoral — E-Commerce That Scales to Millions of Shoppers in 30+ Countries

> Mayoral is one of Europe's best-known children's fashion brands. We engineered the backend that lets them sell seamlessly across 30+ countries — multiple currencies, multiple carriers, millions of catalog requests — without performance degradation at peak.

## Project context

- Client: Mayoral
- Industry: Children's Fashion
- Year: 2024

## Challenge

The catalog browsing experience was degrading under traffic spikes. During peak sales windows, direct database queries for product listings, variant lookups, and inventory checks were creating latency across all regions simultaneously. The shipping layer was also tightly coupled to a single carrier — expanding to new markets meant significant engineering overhead each time.

## Solution

Redis caching layer on the entire catalog browse path, reducing direct DB queries by ~80% at peak. A modular shipping abstraction: each regional carrier is a discrete adapter behind a common interface — adding a new market is a weekend of integration work, not a refactor. Multi-currency handled server-side with 15-minute FX cache. All payment gateway callbacks processed via background jobs — checkout response times are independent of downstream payment processor speed.
