Custom WordPress Plugin Development

The “Optimum” Solution

An Excidium Tech Exclusive!

Premium plug-in development companies focus on building solutions with a large enough market to justify the investment in the solution. If there is not a market large enough to justify the initial investment, premium plugin-development companies won’t invest.

Until now, the only option for clients have been expensive custom development solutions that can take weeks or months to develop and need to be continuously maintained.

With our “Optimum” solution, we can provide clients with semi-exclusive premium WordPress solutions at a fraction of the cost of custom development.

Modular Development

Our solutions are developed as modules that are contained within a single custom plugin.

Update Functionality

You can opt for our Long-Term Support (LTS) service to receive updates and improvements.


Our solution can be enabled or disabled and each module can be tuned to fit your specific needs.

Extreme Website Performance

As our solutions requires websites to be developed with it in mind, we do not offer our optimization solution unless we take on the full development of the website (from start to finish).

What our previous clients said about us!

Chris stepped into a difficult project and was able to take a complex set of requirements and deliver on them with excellence. Working to customize the open-source Moodle platform, Chris showed great programming ability. Over the many months of the project Chris had to work independently and solve challenging problems. He asked great questions and brought new ideas to the project that improved the final product immensely. He’s a great communicator and is able to think holistically to build smart solutions. I’d work with him again in a heartbeat.
