dUCk

dUCk is a global lifestyle brand founded by entrepreneur Vivy Yusof, known for its elegant scarves and fashion-forward identity. As the brand expanded, its digital platforms evolved to support a full-fledged eCommerce experience across web and mobile.

As a Senior Frontend Developer on the dUCk team, I contributed to the development and evolution of the brand’s digital platforms — from custom-built web and internal CMS tools to native mobile applications. The product suite included an eCommerce website, internal management systems, and cross-platform mobile apps.

Initially, I worked on building and maintaining the dUCk eCommerce website and CMS using React and Next.js, integrating with backend services via RESTful APIs. These platforms supported the brand’s global retail operations and internal workflows.

Following a company-wide restructuring, the web stack was transitioned to Shopify. During this phase, I supported the Shopify migration, integrating custom data via Shopify Metafields API to keep the mobile app in sync with the new system.

In parallel, I led frontend development of the dUCk mobile eCommerce app, built with React Native for both iOS and Android. The mobile app offered a full shopping experience, integrated with backend services, and styled using a consistent design system powered by Storybook.
