A Mechanical Engineer turned web developer, Nicholas is mostly known as the author of Akeeba Backup, the most popular backup component for Joomla!. A prolific writer and developer, Nicholas is a regular contributor to the Joomla! Community Magazine, writes regularly on his blog about Joomla! and publishes an assortment of GPL-licensed extensions, both available for free and distributed for a fee. Here's a video interview of Nicholas at JoomlaDay Greece 2011.
Nicholas is the author of the superb Framework on Framework (FOF), designed to work with Joomla: to take the drudgery out of creating Joomla extensions; to mitigate risk from Joomla version changes; and, to expand Joomla's capabilities for extensions.
LaSalleMart 3 for Joomla relied heavily on the FOF, which delivered on every promise, has fabulous documentation, has a terrific Google Group, and is absolutely a role model for my Laravel based LaSalle Software.
