I was in a meeting with a senior software engineer, who makes a shit ton more than me. While sharing my screen he saw flame graph I had for one program I was working on. They asked "what is that?", I was taken back, and said it's for looking at which functions are taking more time. Then I was asked "where did you find it?" I was shell shocked, didn't know how to answer that. Similar things have happened before where I taught them certain things, and they go "great find", like dude, I didn't find it just now. That's basic knowledge if you work with database.

I am not even a developer hire, I'm self learned, and because the company doesn't have many developers they gave me some of the tasks and I'm doing it because it's more fun than my job responsibilities, and when I don't have enough tasks.
