The Challenge

Legacy theme holding back growth

The store was running on an outdated Shopify theme with years of accumulated custom code. Performance was suffering, the codebase was difficult to maintain, and new feature development was slow and risky. They needed a technical leader who could modernize their stack while maintaining complex business logic — including custom discount systems, checkout validations, and integrations with multiple third-party platforms.

The Solution

As Lead E-commerce Developer, I took ownership of their entire Shopify platform and implemented a comprehensive modernization strategy.

Theme Architecture Overhaul I migrated the store from their legacy theme to modern Shopify 2.0 architecture, rebuilding all custom functionality using current best practices. This included implementing performance optimizations that significantly reduced page load times and improved the overall user experience.

Custom Development & Logic The most critical work involved recreating their complex business logic without disruption. I built advanced discount systems using Shopify Functions to handle different customer segments, created threshold-based promotional pop-ups that adapt to cart contents, and implemented comprehensive checkout validations to ensure order accuracy.

Platform Optimization Beyond the migration, I enhanced site performance through technical optimizations, implemented full ADA compliance across the storefront, and established a scalable architecture that supports their continued business growth. The new setup makes it faster and safer to ship new features while maintaining the high performance standards their customers expect.
