The Perfectionist - Comes on time, does his shit, leaves on time. Fixes a whole bunch of issues and never late on deadlines.
The Street Smart Freak - Copy pastes a lot of things from internet, although doesn't know the principle behind, somehow he gets things to work as expected.
The Theoritical Dude - Knows a shit load of theory about computer science and coding, but not that great at coding. Gets into an argument with any who dis-agrees with him on theoretical aspects.
The Sloppy Fellow - Knows the problem, knows how to fix it but ends up blowing things up because of some lack of concentration & focus elsewhere.
