Community Builder (CB) is the most powerful, yet simple and free, Social Networking solution for Joomla. CB has literally hundreds of built-in features and can be extended with extra both free and commercial. We have been using CB on many sites for over a decade, it's extremely extensible, stable, and well supported, we also develop custom extensions for CB.
This job involved fixing issues with a Joomla website with WordPress embedded for the blog, updating the Joomla version, along with the template and all extensions, implementing additional site security measures, along with automated daily site backups including the WordPress site and database, updating WordPress and all plugins
Great guy and great developer.
