A programmer, computer programmer, developer, dev, coder, or software engineer is a person who creates computer software. The term computer programmer can refer to a specialist in one area of computer programming or to a generalist who writes code for many kinds of software. One who practices or professes a formal approach to programming may also be known as a programmer analyst. A programmer's primary computer language (Assembly, COBOL, C, C++, C#, Java, Lisp, Python, etc.) is often prefixed to these titles, and those who work in a web environment often prefix their titles with web. A range of occupations, including: software developer, web developer, mobile applications developer, embedded firmware developer, software engineer, computer scientist, or software analyst, while they do involve programming, also require a range of other skills. The use of the simple term programmer for these positions is sometimes considered an insulting or derogatory oversimplification.
