I feel that. Completely self-learned here. Do not have a dev dayjob ( yet ;) ). Code in the evenings and free time for almost a decade. Got a few mini projects, scripts, etc.

I answer the question like you do.

I'm getting to the point where I was thinking to just say "yes" to "you a dev".

Maybe I am a dev, but a bad one. Always gotta be learning anyway, and that mindset might help fend off some of the impostor syndrome.
