When I first started programming as an employee at Travelocity I discovered a senior Java developer who was really good at CSS and JavaScript. At that time, around the beginning of 2008, there was a very clear division of labor between Java people and front end web people. Java people had absolutely no idea how to write JavaScript. It was so bad that Google wrote a tool called Google Web Toolkit (GWT) that automatically generated JavaScript from Java logic and it was beyond horrible, but there were some Java developers that really needed it.

What I found most interesting about this excellent developer, and of course she was absolutely excellent at her job writing Java as well, was her secrecy. She did not mean to reveal her ability to masterly address CSS and JavaScript concerns to me. She did so because she knew I was super new and it didn't matter. She did not reveal this to anybody else, because she didn't want to compensate for the repeated failures of people around her. In hindsight I can absolutely see why she went out of her way to suppress her capabilities while at the office.
