WordPress freelance developer
one of the most popular CMS platforms
If you don't believe the hype, according to W3Techs, WordPress accounts for 30% of all websites on the world wide web. Amazingly that figure increases to 60% when talking about sites with a known integrated CMS.
Either way WordPress cannot be ignored when exploring the options for your next web project.
Amongst it's many pros, WordPress has a wealth of available free plugins to further enhance your sites features, making it easier to get up and running more cost effectively. Although I should point out that due to it's popularity, security is definitely it's achilles heel, so that has to be seriously considered before starting any new/existing development.
