means A person who writes instructions in a programming language to make software do what it's supposed to do (eventually).

from From 'code,' which comes from Latin 'codex' — a block of wood split into tablets for writing, later a bound book of laws. By the mid-20th century, as cryptographers and early computer scientists needed words for systems of symbols standing in for other meanings, 'code' was pressed into service for both secret ciphers and programming instructions. 'Coder' followed naturally — someone who writes in code — gaining its modern sense as computing exploded in the postwar decades.
