EE Upgrades

Are you running a version of ExpressionEngine that has reached end of life? We upgrade older ExpressionEngine websites to the latest version of EE for a more stable, secure, and performant website that is easier to manage and provides a baseline for further improvements.

Custom Tools

EE allows you to author advanced tools that are easy to manage and modify. Create custom functionality without loading complicated libraries or options you don't need. The CMS can be configured to your needs so that editing and management is easy for a non-technical user.

Performance Optimization

Eliminate excessive or unnecessary database queries in templates. Implement Elasticache, Redis, Memcache or cache partials, fragments or entire pages after PHP output. Consolidate scripts and styles and serve Gzip encoded assets or next generation compressed image formats.

CMS Migration and Design

Is your current CMS or template system limiting your creativity? EE makes no assumptions about how your site should look. This allows web designers to create beautiful custom-designed websites and build the content management experience to your specifications.

Marketing or Business System Integrations

Implement systems that help your team evaluate your progress and reach marketing goals. Connect your web app with third-party software systems to streamline processes, sync data, or automate reporting.

Ecommerce Solutions

We build ecommerce solutions focused on providing your customers the best experience possible. And providing you with custom tools and third party platform integrations you need to manage your business.


We've been building PHP and mySQL websites for two decades. ExpressionEngine has been our preferred CMS following the release of first public beta in 2009. Our team has designed and developed, updated, migrated, customized or optimized hundreds of EE projects. We've been a part of the EE community for over 10 years and have been working with other developers around the world to built best-in-class solutions with each major version of EE, 2 through open-source version 7. If you're currently running EE or interested in migrating to a powerful and flexible CMS, we have the expertise to take your project to the next level.
