Java was released by Sun Microsystems in 1995 as its main development platform. Later it was engaged by Oracle, which acquired Sun Microsystems. Syntax is largely similar to C and C ++. In the official program implementation Java-applications are automatically compiling into a byte-code that may be interpreted for any platform. One of the Java concept features is that errors (exceptions) do not lead to a complete system collapse. Also, Java uses automatic garbage collection for a memory management during the life cycle of the program. Highly qualified BackEnd Java programmer decides when to create objects and virtual machine start freeing the memory after the object is no longer needed. That’s how real optimization works!

MongoDB is database management system that doesn't require a circuit description tables. MongoDB occupies a niche between fast and scalable systems that operate data in the key-to-value form and relational DBMS which are more convenient in queries forming. MongoDB code is written using C ++ and distributed under the license “AGPLv3”. The main conceptual advantage of the system is quite flexible language of queries forming. Information storage and documentation language used in the system is much more productive than others. It may allow you to use resources much more efficiently and comfortably while managing the data sets. Database programming is a very specific IT-field. That is why you may need a highly experienced Mongodb freelance developer to get your DB tasks done. Obviously, if you are rapturously planning to offer a great code challenge, it would be probably better to hire a Middle or Senior Mongodb Developers ;) On the AOG we use sign the contracts in the English jurisdiction, so the freelance developers contracting processes are absolutely secure and trustworthy.
