A computer programmer, also known as a coder or software developer, is someone who writes in a language the computer can understand to allow it to solve a problem. This is an essential part of technology, because without the proper coding our computers, smartphones, apps, and websites wouldn't work properly.

Computer programmers write the code that allows all computer applications to run. They are responsible for the millions of lines of code it takes to run everything from our phones to satellites to EKG machines.

They do this by communicating with computers in programming languages. Applications, systems, and platforms are written in a variety of languages, such C++ or Python. Programmers learn to “speak” these languages and are able to create programs that allow searching, surfing and selfies.

Often, computer programmers work closely with software developers and engineers. The developers create a design, and the programmers carry it to completion. They problem solve and fine tune the details of coding to ensure the program works as designed.

Programming projects vary greatly in complexity and duration. Some require knowledge of more than one language. Others may be year-long endeavors. All require attention to detail. Regardless of their assigned project parameters, highly proficient computer programmers should possess certain key skills.
