Ivan Đurđevac is a PHP developer from Serbia, Pančevo. Long time ago, he found out the "development" word with Delphi. Prior to 2000, the Web was a huge deal, and he decided to pick PHP as his main tool. He started with CodeIgniter as his first framework. After a while, he realized that CodeIgniter did not allow him to write beautiful code to solve problems with design patterns, and he saw it would stay that way, trapped in PHP4. So, he switched to Kohana and Zend Framework and it was a big step forward. FuelPHP was a new kid on the block. It took all the best features from others and created a modern framework. He used FuelPHP to build large-scale applications. At the time this book was written, he used Laravel as his codebase. No matter which framework he uses, clean code is always a priority for him. He will never stop learning from better developers and modern practices.
He has worked for various companies on many projects, such as e-learning platforms, CMS-ES, social network sites, and business applications. Currently, he is working for a USA-based company that builds various internet marketing tools, which collaborate with AWeber, Infusionsoft, and other tools. He is also interested in DevOps and likes to play with Linux administration and set up server boxes and maintain them.
Márk Sági-Kazár was previously working with CodeIgniter, and picked up FuelPHP in 2011. Since 2014, he has been actively developing for FuelPHP, starting with the E-mail package. From the autumn of 2014, he has been an official member of the FuelPHP team.
Mark started playing with programming at the age of 6. While in high school, he worked with several Microsoft languages; Visual Basic is one of them. After finishing high school, he switched to PHP as his programming language of choice. Starting with CodeIgniter, he quickly switched to FuelPHP and delivered his first production application (an e-commerce site) in 2012, followed by IndigoPHP in 2013, which is an application framework and CMS built on top of FuelPHP. Besides his work on FuelPHP V2, he's currently working on some good quality packages such as a SupervisorPHP (http://supervisorphp.com) and shopping cart abstraction, to name some.
