Add charlie to speakers page

Hi! I like speaking, especially at conferences. 🤔

I've done quite a bit of speaking. Most have been for smaller (<200) gatherings such as Rails Girls.

I did a fair amount of academic speaking, including teaching at a university, so I'm comfortable with large audiences.

I don't have any slides for my previous talks, so I haven't put any in. I just say things :)
