I created SkillUpper because I was thinking about how Computer Science learning could be more interactive.

Codecademy pioneered a more interactive REPL style of learning for basic programming.

I felt that this interactive step-by-step approach could be used to learn other parts of Computer Science more efficiently.

Because of algorithms being highly represented in software engineering interviews, it seemed like a good place to start. But this step-by-step format could also be used to teach other parts of Computer Science.
