Because of extensive digitization of different contents and the rising distribution of digital media, especially the smartphone, also the demand of qualified personnel that is able to develop and programm online applications has risen drastically. The need of competent Java-programmers is very high. However, it has to be differentiated what type of Java-developer is needed.
What does a Java developer do?
Most Java-developers take on different kinds of diversified tasks. Depending on the job profile in the requirement analysis, those can include conceptual designs, as well as further development of applications, systems and websites. The job-title “Java-developer” already insinuates what a typical developer has to offer: he has to bring detailed theoretical knowledge of Java, while being able to translate his or her knowledge into practical implementation. Besides that, critical reflection of functional or non-functional requirements and technical conception of software solutions may be amongst the tasks.
Java-developers rely on frameworks like Hibernate or Spring, or take on testing and code reviews. Apart from that, they can be in charge of designing software-architectures and drafting services. Java, Java-Frameworks, APO-technologies like JSON, SOAP, CML and (My)SQL are amongst the technologies that are mainly used. Furthermore, versioning systems like Got or SVN, but also tools like Maven, Jenkins and Jera are used frequently.
Which qualifications must or should be fulfilled?
A university degree or training in the area of computer sciences is a requirement for many companies. Deep knowledge in object-oriented software-development with Java and platforms like JaveSE and JEE, as well as work experience, can be beneficial. Also career changers have great opportunities when being able to present self-developed applications.
Today, the demand of software (and therefore of software-developers) is unprecedentedly high in many lines of business. To realise and implement various ideas, experts like Web- or PHP-developers are targeted specifically.
What exactly does a PHP-Developer do?
Requirements for a PHP-Developer
The demand for PHP-developers is generally high. Nevertheless, also a PHP-developer should bring certain qualifications. For many companies and employers, a completed university degree or training in the area of computer sciences, as well as professional experience with PHP, is amongst the requirements. Apart from that, reliable knowledge of PHP-versions like Yii, Zend and Symfony are always sought-after.
Also lateral entrants, without the qualifications that were mentioned previously, can have the opportunity to fill open vacancies. This, for the most part, is only realistic, when references in the form of self-developed applications are presentable.
PHP-developers that have made valuable experiences in frontend- and backend-areas have a great advantage.
