Freelance ExpressionEngine developer
a powerful licence based CMS
In their own words "ExpressionEngine 4 delivers your message with the most flexible, secure content management system on the planet, without requiring complex programming skills."
ExpressionEngine is another example of a CMS with a great community of developers, in a similar way to WordPress. Whatever you require there is more than likely an existing add-on avaliable to purchase to fill your requirements, if not it has a proven add-on architecture allowing us to create custom features if needed.
For projects where the budget allows, (separate £300 > £600 license/add-on costs) ExpressionEngine gives us the ability to setup a very secure platform with features including e-commerce, member management and even it's own forum module.
