Hourglass Cosmetics - Custom Palette Experience on Shopify Plus

Build a flexible custom product experience for Hourglass that allowed customers to create personalized palette combinations while maintaining a seamless Shopify cart and checkout flow.

The project also needed to support operational workflows, purchasing rules, data consistency, and long-term maintainability within the broader Shopify Plus architecture.

The product experience required functionality beyond standard Shopify product and variant behavior.

Key challenges included:

• Supporting dynamic customer-selected shade combinations

• Representing custom product configurations reliably throughout cart and checkout

• Enforcing purchasing and validation rules

• Connecting the customer-facing experience with internal operational workflows

• Keeping a complex product experience performant and maintainable

As part of my work at Vaan, I helped build the technical foundation for Hourglass Cosmetics’ Custom Palette experience on Shopify Plus.

My work included scalable product-configuration logic, Checkout UI Extensions, purchasing validation, Admin API automation, data migration tooling, and improvements to core storefront components.

The solution connected a highly customized frontend experience with Shopify’s cart, checkout, and backend workflows while keeping the system maintainable and extensible.

• Built custom product-configuration logic supporting dynamic shade selection and personalized palette combinations.

• Developed Checkout UI Extensions to support custom purchasing and validation requirements.

• Implemented logic to ensure configured products remained consistent through cart and checkout.

• Built Admin API automation to support operational workflows.

• Improved shared storefront components for performance, maintainability, and reuse across the broader Shopify implementation.

The Custom Palette experience launched successfully and contributed to 73% inventory sell-through within 9 days.

Beyond the commercial result, the project established a scalable technical foundation for personalized product configuration, checkout extensibility, and supporting operational workflows within Shopify Plus.
