1# Coders

 A Coder is a person in charge of writing the code that makes most of our apps run properly. Those who are coders have the ability to create software that can be used not only in apps but also in video games, social media platforms, and many others. Coders sometimes cannot do all the phases required in the making of a software, like designing or testing, they mostly take part only in the phase of writing the base code.

2# Programmers

Programmers are able to create computer software in any primary computer language, like Java, Python, Lisp, etc. Programmers are said to go beyond coders, they may specialize themselves in one area or may even write instructions for a wide variety of systems. Programmers can be similar to Developers but the ones who implements are not the same as the ones who can design or do a well class structure within the software.

3# Developers

Developers can write and create a complete computer software out of nowhere taking care of the design and other features. They are key for the development of any software applications; they are also experts in at least one programming language. Some people consider them true professionals that can take care of all the generals. Developers can sometimes be more general when it comes to the development of a software, unlike Programmers.

4# Software Engineers

Software engineer is an individual that applies the principles and techniques of computer science or software engineering to everything regarding the development of a new independent software; from analyzing what the particular needs of the user are, going through the design, maintenance and testing, and even the final evaluation of the software. They are able to create software’s for any kind of system as operating systems software, network distribution, compilers and so on. They often have a college degree and can prove things theoretically. 

Another way for understanding the difference between a  Coder, a Programmer , a Developer  and a Software Engineer  is seeing them as as a hierarchy or as stair, where  the Coder can be found in the low section of stair  and  the Software engineer can be found at the top. Maybe to you  all these job tittles may mean the same because you once  knew  a Developer  that could do everything a Software Engineer can, but there are really some differences between them are worth knowing.
