  • Guaranteed Rent Provider Website

    A WordPress website for a rental agent offering guaranteed rent for landlords.

    I collaborated with a web design agency that provided the design. The website was built in WordPress from a completely blank theme, which led to a high-speed site with high page speed. The site was built with ACF allowing the admin to easily create their pages.

  • WooCommerce Website

    Building this website's theme from scratch, I created many custom blocks for the client to use in WordPress's new Gutenberg editor.

    A modular approach allowed the client to get the most out of their website, while great page speed and SEO enabled this website to rank extremely high in Google.

  • Cupboard Builder

    With the built-in custom PHP, JavaScript, and jQuery and interacting with WooCommerce, this tool allows users to fully design their cupboard to their exact requirements. They can choose the size and number of doors and choose from a wide variety of colors and finishes for all different doors and frames, which allows them to create a bespoke cupboard. The system then enables the users to order the cupboard for delivery. The user can watch their cupboard come together with a live preview throughout the design and building process.
