  • NASK Website – Bilingual, FSE-Based Custom Theme

    NASK Website – Bilingual, FSE-Based Custom Theme

    I developed a fully bilingual website for NASK, built on top of WordPress using Full Site Editing (FSE). The project combines custom-written code with PHP-based functionality to extend the native capabilities of the CMS. I designed and implemented a bespoke theme, leveraging WordPress Theme Editing tools while adding tailored components and logic to match the project’s unique requirements. The result is a modern, flexible, and scalable website that supports two languages and is easy to maintain and expand.

    VENTINO Website – E-Commerce Design With Custom PHP & JavaScript Tools

    The VENTINO website was designed as a clean, user-friendly e-commerce platform focused on clarity and a smooth shopping experience. The layout features intuitive navigation, an advanced product search, and a streamlined checkout process, making purchases fast and comfortable for users.

    A key element of the project is the custom PHP and JavaScript code I developed specifically for VENTINO. This custom-built tool serves as a device selection assistant for ventilation system designers, helping them quickly match products to technical requirements.

    The website combines modern aesthetics with large, high-quality product images and detailed descriptions that support purchasing decisions. Its fully responsive design ensures an excellent experience on both desktop and mobile devices.
