Cloudfest.com - The World's Number One Cloud Conference

Custom website powered by WordPress with tailor-made themes and plugins. I coded the front end and back end of multiple themes and plugins that allow many editors to correctly and efficiently display their content. This website is very content-rich, and to enable maximum flexibility, I fully customized and rebuilt the front end of a popular page builder so it was possible to use a page builder and have maximum front end performance with zero penalties from bloated code.

This website has its own custom-built GraphQL API that powers a React application to show the huge agenda that spans across multiple days and venues at the same time.

Intrehouse.nl - A Letting, Buying, and Selling Property Franchise

A complex content-rich website that I rebuilt and extended with new functionalities after brainstorm sessions with the client. The theme and its core property and content management plugins are custom-coded for maximum editor flexibility, long term code stability, and front-end performance.

This project is also connected to a third party CRM that feeds property data into the website. A custom-built Rest API system exposes data to various JavaScript powered UI elements across other satellite websites installed under subdomains.

Namescon.com - The World's Number-one Domaining Conference

A custom WordPress-based project built with tailor-made themes and plugins.

I built a huge set of components for the back-end editor to allow maximum flexibility for the content editors and the best front end performance to aid SEO effort.

All the pages were built solely by the website editors based on the custom components developed for this project. This web project features several custom-built plugins to handle various content data types, speakers, agenda, news, and logos.
