Selected experience
Over the years, I’ve built and developed websites for agencies, businesses and institutions. Here are a few examples of the work I’ve been responsible for.
As the primary developer, I develop and maintain a WordPress Multisite platform for a public institution. I work directly with the client, translating organisational needs into new features and improvements to existing websites.
One of my key tasks was making imports from external data sources more reliable. I analysed and improved the process so that data arrives in WordPress consistently. To handle failures, I built an admin tool for retrying imports and an option for editors to upload an XML file manually.
I also supported a hosting migration, helping diagnose performance issues in the Kubernetes environment after the move. Ongoing development includes custom plugins, REST endpoints for mobile apps, and accessibility and UX improvements.
I implemented the front-end of a custom WordPress theme for an international company’s blog, translating the supplied designs into a responsive, accessible website with optimised assets.
I built a set of ACF Blocks: an article slider, lists of recent posts from a selected category, and CTA sections. Editors could choose the number of articles per row to create different grid layouts.
The editorial team gained the tools to build varied pages independently using reusable components, while keeping the blog’s design consistent.
I implemented the complete front-end of a research initiative website for a UK university. The design combined full-screen sections, video and Lottie animations into an experience resembling an interactive presentation.
A particular challenge was using a Lottie animation as a mask to reveal the video underneath. I resolved differences in how browsers rendered the mask, eliminating visible video edges leaking beyond it.
On mobile, I rearranged the elements and adapted the animations to smaller screens. I replaced section-by-section scrolling with natural page scrolling to make the website comfortable to use on phones.
Agency projects are described anonymously to respect client confidentiality.
