Skills description

C#
C# is object-oriented programming language for networking and web development. It was originated in 1999 by a software engineer who cooperated with a team developing new language as a complement to Microsoft’s NET framework. At first C# was developed as C-Like Object Oriented Language and in 2000 it got its name - C# (pronounced as see sharp). C# technology is rather new, but it has updated features of C and C++. This technology requires good skills at memory leaks and eliminating mistakes issues. The C# programming process is more simple than C and C++ and more flexible than Java has. C# source file may define any number of classes, structs, interfaces, and events. If you have need in C# developers for your project go down the list and choose candidates you like.

Java
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!

Besides, .NET is a versatile cross-platform technology. For now, there are at least Microsoft Windows version called FreeBSD and the option for Linux, named DotGNU.

SQL
If HTML is a basis of frontend programming, then the SQL is a key to the deep database programming and managing of almost every existing DBMS. Using this language, you can manage different data, filter and analyze information even in very large volumes. In general, SQL first appeared in 1974, but it is still widely used by programmers who work with different databases platforms such as MySQL, because of its versatility and uniqueness.
