As part of the first stage, we prepared an extensive UX/UI design of the Sellineo online store, covering a total of 29 views, including the home page, category pages, product cards, project pages, and subpages presenting the company. One of the main assumptions given by the client was to create a website that would showcase the beauty of the materials and finished products so that visitors could already "feast their eyes" while browsing the offer and naturally feel the quality of the presented solutions.

A key point of the project were the extensive category and product pages, which were meant not only to organize the offer, but also to guide the user through the process of learning about the materials, workmanship quality, and personalization options. The content provided by the client served as the foundation for the layout, ensuring educational value while naturally highlighting the most important product information. The design was enriched with photos of products and projects, emphasizing the beauty of the materials and finishes used. Already at the design stage, we also took care of a modular structure of the views, preparing blocks that could be reused when building landing pages and further subpages.

The store was implemented using the Custom WordPress Development model, with a full reproduction of the prepared graphic design on the frontend side. We based the implementation on ACF PRO fields, the TailwindCSS framework, Swiper, Docker, and a GIT repository, creating a flexible and scalable environment ready for further expansion.

A key element of the implementation was preparing reusable ACF PRO blocks, which allow the client to independently manage content and build further landing pages without the need for developer intervention each time. We ensured excellent display of the store on many types of devices (RWD), from desktop computers to tablets and smartphones, as well as high performance and loading speed, especially on the German market. As part of the work, we adapted and integrated WooCommerce sales functions, including payments and deliveries, also preparing the store for future sales in other countries and the development of new features. Before the store's publication, we carried out a migration of over 2,000 products as well as 500 blog posts, project entries, and Meta data, ensuring a smooth launch of the store and its readiness for further development.
