I’m an expert web developer with the attitude in performance and security in web application development.
during the previous years that I come to a friend with yii framework I found it right choice when I need scalability and high availability without compromising performance. but every thing changed from those year,new projects has been born and I think Yii should still be Yii!
It should be the fastest and securest php framework over the world. it should support with built in component high performance scalable project like Apache Cassandra, MongoDB and etc as built in support db, Redis Cache component and many other good projects available in these days.
