Join your local chapter of Toastmasters. While I don’t have direct experience, I know people who felt introverted come out of Toastmasters feeling confident about public speaking.
Everyone has some fear of public speaking in the beginning, so you are not alone. Practice is key. If you can find some way to make presentations in front of a small group of people that’s a good start.
Having well polished slides in your presentation goes a long way. Give your slides a theme or some style. Don’t just state a problem and how to solve it. Tell a story. We live in societies where narratives reign. People connect with a narrative more.
If you plan to do live coding, have code snippets on hand you can easily paste into the code, unless you type extremely fast, which I have also seen, but that is rare. Keep it simple in the beginning.
I went from being terrified of public speaking to being a speaker at national conferences. You can do it too! Best of luck!
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
