programmer

A computer programmer, sometimes called a software developer, a programmer or more recently a coder (especially in more informal contexts), is a person who creates computer software. The term computer programmer can refer to a specialist in one area of computers or to a generalist who writes computer programs.
A programmer's most often-used computer language (e.g., Assembly, C, C++, C#, JavaScript, Lisp, Python, Java) may be prefixed to the term programmer. Some who work with web programming languages also prefix their titles with web.
