My first tech talk was a disaster. I spoke too fast, forgot my demos, and ran 15 minutes over time.

My most recent talk got a standing ovation from 200 engineers.

What changed: practice, structure, and one key realization — technical talks are stories, not lectures.

The structure that works for AI talks: start with a problem the audience relates to ("have you ever deployed a model that worked in testing but failed in production?"). Show the journey of solving it, including the wrong turns. Share the solution with enough detail to be useful. End with what you'd do differently and what the audience can apply tomorrow.

Practical tips that made the biggest difference: demo LIVE when possible — recorded demos are boring, and the risk of live demos creates energy. Rehearse at least 3 times out loud — reading slides in your head is not rehearsal. Time yourself — running over is disrespectful to the audience. Have backup slides for likely questions.

The career impact of public speaking is outsized. One 30-minute talk reaches more people than months of LinkedIn posts. Conference organizers remember you. Audience members become collaborators or clients.

Start small. Give a talk at your team meeting. Then a local meetup. Then a conference.

The fear never fully goes away. But the value is too high to let fear win.
