I worked with a few devs who were at a very beginner level, but they worked with non-technical people for many years often over 10.
Somehow these people managed to never interact with better devs than themselves and have the feeling they know everything because they know more about tech than their non-tech co-workers.
It's tough to work with these people when they're much older than you because they think they are "wise" and you are just some young hipster.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
