Challenge: The client required Shopify Custom Theme Development to migrate from Magento to Shopify Plus due to high maintenance costs and slow page loads. They faced significant revenue loss during peak traffic, with page load times exceeding 6 seconds.

Solution: A team of 2 Shopify architects and 3 developers executed a 12-week migration.

The migration involved moving 15,000 product SKUs and integrating with Klaviyo for marketing automation.

Results: The new storefront achieved a Lighthouse performance score of 95. Page load time dropped to 1.2 seconds, resulting in a 45% increase in mobile conversion rates and a 30% reduction in bounce rate within three months.

Client: Regional healthcare supplier serving 50+ hospital networks requiring strict data compliance.

Challenge: The client required Shopify Custom Theme Development to create a secure portal for medical supplies, adhering to HIPAA regulations. The existing platform lacked necessary audit trails and secure authentication, risking non-compliance fines.
