Depending on the complexity of your website or application, the CMS I use may be: a completely custom CMS; or, a widely used open-source CMS. The vast majority of websites that people ask for can be built with the latter. Only bespoke business systems/applications ever require a totally bespoke CMS. Whichever CMS I install on your product, I will provide you with a manual on using it.
There are several, widely used CMSs which greatly reduce development time and therefore save the end-client money. Some of these CMSs are each introduced below. You may have heard of them, or you may even have experience using them. Of course, your knowledge of these things below are not important, it’s just here for your curiosity (or if you wanted to know if I use any particular CMS). These CMSs aren’t just for the content management side of things, but also to speed up the development of the website it’s self (and therefore saving the end-client money, again).
If you have heard of (or used) any open-source CMS, you will probably have heard of WordPress. WordPress is the most-used of the open-source CMSs and I use it frequently. WordPress is the simplest to use of the CMSs and so it’s great for allowing my clients to edit the content of their website, with no technical knowledge. WordPress can be used on the majority of websites, that can be built using any open-source CMS. WP can be used for almost anything: from the simplest website, to full-blown eCommerce websites. I build a lot of websites with WordPress. If you require any services which include this CMS, then have a read of the WordPress Development page.
Joomla! is another open-source CMS, which can be used for almost any type of website. It’s slightly more powerful than WordPress, but, for all intensive purposes, Joomla! does exactly what WordPress does and the two are interchangeable in most projects. I’m just mentioning Joomla! here in case you were looking for a Joomla! developer.
