I'm Kevin Chileong Lee and I'm wokring for more than 10 years in web development with TYPO3 as main focus. I develope individually solutions, create page templates and give online courses and private lessons in TYPO3 extension development.
In my opinion TYPO3 is one of the best content management system that exists in the open source world. There is no other CMS where the usability for the editors are this good and also the code quality in such high standard.
I love TYPO3.
