The development of a WooCommerce theme from scratch allowed for the creation of a fast and modern online store, tailored to the individual needs of the client. Gulp and Webpack were used in the work for optimizing the build and quick code updates, SCSS for flexible styling, and JavaScript for interactivity. The main logic of the store was implemented in PHP, with deep integration of WooCommerce, while dynamic animations added using the GSAP library provided smooth transitions and a pleasant user experience. Additionally, a custom plugin for the contact form was written, allowing for convenient handling of customer inquiries and increasing communication efficiency.
