TYPO3 Expert & Instructor
I'm Kevin Chileong Lee and I'm looking forward to your visit.
I've been working as a TYPO3 full stack developer for over 10 years and since then I've made TYPO3 templates from dozens of page templates and written TYPO3 extensions.
I have been a TYPO3 lecturer on Udemy for over 4 years and have been able to accompany more than 1000 participants on their way to the TYPO3 CMS.
In addition, I was allowed to hold several private coaching sessions for TYPO3 in German and English.
In the following I will show you my most important skills as a TYPO3 full stack developer with over 10 years of professional experience in this area.
I create page templates, frontend plugins and custom content elements for TYPO3 from version 6.2.
I specialize in Bootstrap.
I develop backend modules, extend or change TYPO3 form fields and configure via TypoScript.
I specialize in jQuery and jQuery plugin development.
Needless to say, I only write in HTML5 and CSS3.
I only do frontend development for Chrome, Firefox, Edge, Brave.
I regularly use Subversion, Git and GitHub for my version control.
Thanks to my hobby of landscape and architecture photography, I can handle Adobe Photoshop and have the latest version of Adobe Photoshop.
I also work in print-on-demand and can therefore also use Affinity Designer (similar to Adobe Illustrator).
Although I have learned and master various programming languages, I only offer my services in PHP.
I write clean object-oriented code from PHP 5.6 to PHP 8.1+. I document my code in German or English. In addition, I adhere to the TYPO3 Coding Standards and actively work with the TYPO3 API.

Specialist for media and information services in the library department

The name of the training is just as boring as the training itself - at least for me.
Nevertheless, I am very grateful to be able to do this training and to have successfully completed it. Because it was in one of the most difficult phases of my life ever.
I would especially like to thank Mr. Vito Bilello, Ms. Kristina Johne and Ms. Sonja Barthelmes.
