Power Planet Online is an international electronics store built on a headless architecture: Umbraco as the decoupled CMS for content and commercetools for products, orders and the shop logic. The frontend is a Next.js application with React 18, fed through GraphQL and the official commercetools SDK; complex forms and validation rely on React Hook Form and Zod for strict typing and a smooth user experience.

I built reusable, accessible components with Radix UI and Tailwind CSS: navigation, forms, advanced inputs, sliders and interactive elements, with Lucide React icons and Simplebar and react-responsive for the visual polish. I also helped build and maintain the design system in Storybook, with visual tests in Testing Library and Jest, and optimised performance with SVGO, svg-sprite and Webpack bundle analysis.

Beyond the components, I took part in key frontend architecture decisions: the folder structure, the internal conventions and a dynamic module loading system built on a custom grid.
