full stack developer

The fashionable term "full stack developer" refers to the know-how in the area of front-end and back-end technologies. Today, front-end development usually only includes "web software" (often only HTML, CSS and JS), which a full-stack developer can develop together with the "server software" (often only PHP and SQL).

My knowledge is much more comprehensive: the development of real desktop software, own web servers, the development of own operating systems... up to the development of own hardware and computers.

This knowledge about the internal processes allows me to develop performance- and hardware-optimized code. This is even possible in a hardware independent programming language like JAVA. As an example, the timing of the communication is important for the Mobile APPs in order to save battery power.

This overview will be printed without navigation when using the print function.
