" Currently, there are several frameworks and developers that work with this language, among them the Java Spring Developer stand out.

What is Spring? Listed as the most popular Java framework in the world, it is used for microservices since it can deliver functions at the production level with the ability to evolve independently. It also stands out for its asynchronous and non-blocking architecture, helping the Java Spring developer make the most of their computing resources.

A Java Spring developer usually makes use of this framework to create and maintain business software applications. Among the skills and knowledge that you must have, the following stand out:

• Basic knowledge of Java

For any Java Spring developer who wants to be successful in software development, having knowledge of Java is imperative. Being able to create an application, be it web or mobile, with the use of Java is one of the first tests that you must pass to be able to work with Spring.

• Experience in different programming languages

It is not just enough to be an expert or to be able to handle a single programming language or just a framework. Sometimes to create a web or mobile application it is necessary to make use of several technologies and thus have a project with a perfect finish.

• Expertise in non-Java technologies and frameworks

DevSkiller, a developer selection platform, published an annual IT skills report that reveals additional technologies that Java developers learn alongside their primary language. Up to 26.27% of companies are looking for developers with Java and SQL skills. Meanwhile, 6.85% of employers need specialists with a Java + JavaScript stack.
