  Google-Translation API I have been working with this API for several years. The quality of the translations has dramatically improved – but not always perfect. I use the translations of the Google API, save them in spreadsheets and give the user the ability to change the texts manually at any time. For that I have developed some cool UIs.  Read more under Projects.

2. My personal characteristics and concepts
    As a longtime freelancer, I have a high degree of initiative and personal responsibility. I work carefully and have high demands on the quality of my work. New conception and programming of planned web appearances is the norm for me.
    I have a real passion for new trends and technologies. Especially in the environment of Laravel and Javascript. 
    I learn daily through online video courses (such as Laracast, Udemy, CodeCourse and many others). I read relevant newsletters daily (eg Laravel News, Nick Basile, Spatie, Vue, Javascript weekly etc.).
    I collect all information from one of my structured knowledge bases (Pearltrees) . This knowledge base serves me to meet every new requirement. This knowledge base is continually being extended and supplemented by me.
    I develop reusable code and modules. I have developed a variety of user interfaces in my projects. Always with smooth animations.
    I’m constantly working on maximizing my apps in terms of speed. Keywords: Caching with Redis, DB optimization etc.
    As a freelancer, I always communicate directly with my clients. These were not IT professionals but entrepreneurs, shopkeepers etc. I am able to translate verbally formulated customer requests directly into the application. The customer relationships last several years, since there were always requests to expand the application.

3. My priorities of the last years
  Laravel Development of a backend that serves as a boilerplate for various front-end applications.

Various in-house developments for reusable user interfaces (UI).

Building an optimized CRUD. Content Management (Ajax-based).

100% true multilingual, thank bank based, using Google Translations API. Goes well beyond Laravel’s own system of long folders. Any language is possible, any number of languages ​​are possible. Separation of backend and frontend. 

Development of a sophisticated key / value table with integrated texts and translations. Basis for a multiplicity of user interfaces. Logical switches, color picker, selects and more. This is what configuration wizards and design wizards are made of for any conceivable purpose. Everything with help texts in any languages.  

   Javascript I have worked intensively with EC5 and EC6. I also went deep into Vue. I’m about to replace my jQuery-based functions and modules with Vanilla-JS or Vue.

I’m interested in Vuetify, which offers UI components based on Vue. Just dealing with NUXT.

   CSS Have learned SASS including compiler. I have Bootstrap 4 integrated into my laravel applications. Have Animate.css integrated. I’m excited about Flex and Grid, which simplifies things a lot in terms of responsive design.
  Redis I’ve learned to implement my own cache mechanisms based on Redis. Have an interesting approach to cache key / value / translations, not only Table / Record based but Table / Record / Field based.
  until 2015 I developed my own shop system over several years and continuously expanded it. Much of what I once developed there I would like to add in a modern way to my Laravel-Boilerplate.

The shop system is still in use. Particularly complex is the backend. Although not up to date, (PHP 5.6) but still fast. Contains many good ideas that I am continuing to develop and is currently migrating to Laravel.
