Speaking at (technical) conferences and meetups is excellent for you and your career, but what happens when you want to but you don't know what to talk about?
I found myself in this exact scenario when I was asked by Eunice Allela to speak at the Women Techmakers Women Developer Academy SSA, so I decided to talk about that instead.
Today, I gave a 30-minute presentation and spent the remaining 30 minutes answering questions. I even helped a participant come up with ideas for her talk during the session.
