Custom Plugin Development

Tailored WordPress plugins that add the exact functionality you need. You get solutions built around your internal workflow, including custom integrations and automation where off-the-shelf plugins fall short.

When Custom Plugin Work Makes Sense

Custom plugin work is usually the right route when your process does not cleanly fit off-the-shelf plugins, or when combining multiple plugins creates fragility and operational drag. Instead of forcing your workflow around generic tooling, we build functionality that matches how your team actually works.

Discovery and Build Approach

The engagement starts with practical discovery: what actions users need to complete, what data must be stored, what internal controls are required, and which third-party systems must connect. From there, we define plugin architecture, admin experience, validation rules, and compatibility requirements before implementation.

Maintainability and Future Growth

During development, we focus on maintainability as much as features. That includes clear code structure, sensible settings screens, robust error handling, and compatibility with WordPress core and existing plugins where relevant. If extending an existing plugin is the better long-term decision, we take that path instead of rebuilding unnecessarily.

You end up with a plugin that supports real business operations, reduces manual work, and can evolve as your requirements change, without accumulating the technical debt that often comes from quick-fix customizations.

Client Testimonials

James Whayman has been a precious partner for the past 5 years. I have rarely found someone so professional, dedicated, kind and responsive. He gave a great boost to my website that is now on first page in Google research and I could not be happier with the services that he provided me. I have been impressed with his helpfulness every time I was not able to do something myself or in case of emergency. Highly recommended!!!

WildPress has been really helpful in building our website and providing ongoing tips, support, and advice in a timely manner. The site works nicely, looks great, and is easy to manage for someone new to it. Support has always been prompt. Thanks, WildPress!

The Centre for Nomadic Studies is an academic research centre focused on the political economy of nomadic cultures, conducting interviews with semi-nomadic communities and digitizing archival materials and photographs from 20th century explorers and travel writers.

I had seen a website James designed for another King's College London research centre and was impressed by its clarity, formatting, and presentation. I wanted that same standard for the centre I was starting and James delivered.

The experience was excellent. James was patient with a wide range of uploads, always responsive, and happy to jump on a Zoom to talk through changes. Since launch, we've already had people reach out and new partnership conversations started. I would absolutely recommend James.

James is a pleasure to work with: highly skilled, a fantastic problem solver, personable, and easy to collaborate with. We worked closely on a bespoke subscription product and e-commerce site, and he was integral to its success. I would highly recommend him.

When I started as a personal trainer, I underestimated the importance of having a website and online presence. After deciding to build one, James made the process clear from the start. He delivered a site that was easy to navigate, guided me through basic customization, and offered ongoing support. I couldn't have asked for better.

Everyone at King's College London is in love with the new CSGS website, from the faculty in our department to the higher up deans. It's a relief to have a web presence that matches the awesome research reputation of our university.

We're honestly really happy to recommend James for web development-- he's very thoughtful, reliable and always tries to match the web design & functionality to one's mission and KPIs. We're very grateful to have worked with James and are ready to recommend him ten times over!

I recently started my own business in the real estate sector. James provided great advice, helping me with the launch of my website and my social media accounts. I would recommend his services to anyone looking for guidance on improving their website.

We have worked with James for several years on our British Science Festival and British Science Week WordPress websites. Thanks to James, the websites have gone through several incarnations and evolve to get better each year. James is professional, friendly, responsive, and always provides a detailed explanation of each stage of the process, including instructional videos.

It works well for me as I like the fact I am speaking direct to James who is building the site rather than speaking to a junior account manager which you get at many agencies.

After the initial build was completed, James is managing our site and helping with a lot of changes we're doing as we grow.

James worked with me on a sales site for a piece of software. It was a complicated and, at points vague, brief with multiple implementation options and, at the start, unfinished designs. He worked incredibly quickly, producing code of a very high standard that was meticulously organised. More than that, he worked with us to solve problems; coming up with solutions to design and functionality challenges. Throughout, he was a pleasure to work with. He's someone I'd strongly recommend for any WordPress build-outs.

I've said this to other people, but James is very smart. He's not just a developer, he's good at problem-solving. He can come up with a few solutions and talk them through with me.

Some developers I've worked with need total direction. I like that James can get on with it without being told exactly what needs to be done, particularly with the more complicated builds.

A huge thank you to James who was my biggest support to create a website that supports my passion for fashion. His wide knowledge, great skill set and continues support with new ideas helped to create my website. It was great to see how the site was developed step by step, James would always make sure to talk me through each stage. I would definitely recommend his services especially if you are looking for a friendly approach and high-quality work.
