WordPress Plugin Development

To ensure the perfect plugin solution for every unique situation, we prioritize optimization and compatibility.

Our team of WordPress developers uses every opportunity to upgrade existing plugins and eliminate extra features. If our experts find out that plugin architectures aren't sustainable, we craft custom-made solutions optimized for speed and usability.




Scalable Plugin Development

At DevriX, we pay attention to every small detail and optimize every single component of your web platform.

Whenever possible, we optimize existing plugins, exclude unnecessary components and features and make separate plugins play well together. Whenever the plugin architecture isn’t stable or easily detachable, we build custom-tailored plugins that solve your problems in the best way possible, optimized both for speed and user experience.

Our team of professional WordPress developers specializes in PHP and JavaScript development and has built various applications in Java, .NET, Python, and other programming languages. We are software engineers and WordPress is our tool of choice.

WordPress Plugin Development Standards

Our team of WordPress developers is deeply involved with the WordPress community and development ecosystem. We always follow the best coding standards to provide proven, professional solutions.

  • Stability

  • Performance

  • Security

  • Backward compatibility

In order to ensure consistency in our WordPress development workflow, we have designed a plugin framework and released it to the public. Hundreds of plugins have been built on top of our infrastructure toolkit for building reliable plugins and this ensures the seamless integration with the WordPress core, existing themes, and other plugins integrated within the platform.

Our plugin framework has also been used in various WordPress training courses for developers and entry-level WordPress experts eager to get up to speed with the best industry practices and produce high-quality code.

Why Custom Plugin Development?

While off-the-shelf plugins are great to get you started, they may not provide the tailored experience your venture needs for long-term success.


Plugins available for sale (or free for use) are generic and designed to solve various problems for multiple industries.

This adds additional complexity that would backfire with multiple plugins hosted in an environment serving a lot of traffic.

They are acceptable for starting blogs and small websites, but the added complexity and performance overhead is accumulating and leading to downtime, server outages, or simply poor user experience for customers browsing a website running several of these plugins.

A 50-millisecond delay is hardly noticeable for a small website, but when 10,000 users browse your website, that results in over 8 minutes of lost time, leading to lost opportunities and sales.

The more generic plugins you use, the more that number adds up and causes a dramatic impact on your website’s performance.

How to Assess a WordPress Plugin Development Company?

There are several things that we look for in our WordPress plugin developers.

1. portfolio

Everyone can contribute to the global and official WordPress repository. There is a contribution form that requires a plugin name, a brief description, and a link to the plugin. The plugin review team conducts a code review and approves the plugin within days if everything works smoothly.

Some candidates may also be involved in WordPress Core development. At DevriX, we have 9+ WordPress Core contributors who have successfully received their commit props while working with us.

2. Other proof of plugin development work

Usually GitHub, Bitbucket, GitLab, or another open repository where we can review sample plugins and their development over time. All VCS allow for browsing iterative commits and analyzing how someone thinks and applies changes over time (which many people forget).

3. Knowledge of WordPress APIs

There is a fairly detailed list of WordPress APIs available and most developers have utilized at least a dozen of these. Asking for code snippets and practical projects utilizing them as well as details about how they work or what options do they provide, where is data stored, and what sort of sanitization is required or included out of the box helps out.

4. PHP expertise outside of WordPress

Given that a WordPress website may be built and launched without coding experience at all, programming experience with PHP outside of WordPress is also important to us.

WordPress developers often don’t need to deal with database management and creating their own schemas, create admin panels and deal with user sessions, build templating engines with routing and rewrite components, or even implement basic features that are mandatory for custom projects.

5. Adherence to the Coding Standards

There are public Coding Standards for WordPress projects focusing on PHP, HTML, CSS, and JavaScript. There’s an accepted set of development best practices and coding conventions that should be followed by plugin developers in order to be backward compatible and maintainable as a project grows.

6. Understanding the surrounding ecosystem

WordPress plugin development is usually a part of building an ongoing application that depends on other aspects. Aside from other programming languages interacting within and with the website, there are hosting specifics and server configuration arguments that developers should know about viable tools like WP-CLI, and a rough understanding of how the WordPress project grows and develops over time.

Staying in touch with the WordPress community and the make/org websites means that the developer is keeping up with the latest trends and is aware of what changes would be required for the project over time. We’ve declined project offers for components that were scheduled for the next 2 versions of the WordPress Core itself as it makes no sense to build a replica of something that would be available to tens of millions of site owners in 6 months from now.

7. Computer Science background

We don’t care about graduates. Most of our technical staff have graduated successfully (although some of us tried). But there’s a lot going on beneath the surface.

WordPress is a CMS built with PHP and JavaScript handling data in a MySQL database. Programming knowledge is required, as well as algorithms, data structures, and ensuring code readability, stability, security, and performance.

The CMS works on top of a web server (Apache or nginx) through mod_php or php-fpm. Understanding how web servers work and process request and all stability and data management strategies is important.

All of that runs on an operating system coordinating and interacting with the computer hardware. Understanding the impact of CPU spikes, maxing out RAM storage, hitting the server with heavy I/O and best practices for optimization, caching, offloading resources, and denormalizing databases are certainly beneficial.

Then there’s the networking aspect and sending resources over, the TCP/IP protocol and all. In-depth knowledge isn’t required but simply writing code without any clue what’s going on down there is simply unprofessional.

8. Technical interview

During the interview, we go over all of the steps above. On top of that, we discuss accomplishments and complex problems that have been solved both from a business and technical standpoint. If an applicant says that they’ve created a page template with 2 input fields as the biggest accomplishment, that’s definitely a blocker.

We may also touch on some of the WordPress APIs and discuss what experience candidates have or what do they think those components actually do. Good examples are the Options API, Settings API, or Transients API in terms of data management and processing. Adding custom post types or taxonomies is doable within 20 lines of code or so, but it does so much more underneath that matters for data governance and ongoing maintenance.

9. Test projects

We ask candidates to fill out an interview form asking various questions about PHP, WordPress, JavaScript, and SQL. Most of those are fairly basic (such as “what’s the difference between a single-dimensional and multidimensional array” or “how to retrieve the count of elements in an array”) yet some candidates fail to respond these.

We ask them to build a fairly simple project that could be developed within 2–3 hours by a plugin developer with a year of programming experience. That’s usually a simple plugin that registers a post type (say, Events), and a corresponding category (Event Types), registers a metabox with a couple of fields (such as Start Date and End Date) and does a couple more minor things.

We even provide our Plugin Development Framework with 6 pages of detailed documentation for each common API and how it actually works that some candidates can use as a starting ground.
