Computers are very complex machines, yet people operate them without any technical skills. They just interact with the graphical interface, without knowing what’s going in the background.
Well, every element you see on your device is created by a developer. But who are these people exactly?
Nowadays, programmers are considered new rock stars. Below, we have mentioned some world-class coders who have changed the world with their creative minds and influenced people to become a better programmer.
