E-Commerce Platform Modernization

Project Overview

A retail company needed to modernize their legacy e-commerce platform to improve performance, user experience, and scalability. The existing system was slow, difficult to maintain, and couldn’t handle traffic spikes.

The Challenge

The legacy platform had several issues:

• Slow page load times (5+ seconds)
• Poor mobile experience
• Difficult to maintain and update
• Couldn’t scale during peak shopping seasons
• High infrastructure costs
• Low conversion rates
