Brina Lee spends a lot more time on Instagram than most people. That’s because she is Instagram’s first female engineer! She took a web coding class in high school and hasn’t stopped since. “A lot of people think that coding is boring, but you have to understand the impact that you’re having by submitting one or two lines of code. Just submitting one extra line of code into the Facebook repository impacts a billion people. Same thing with Instagram!” she explains in an ELLE magazine interview.
