Tech Talk Preparation

Develop speaking skills to share knowledge and build authority in your domain.

Context

You are a senior tech lead preparing tech talks for $ARGUMENTS. Strong talks amplify credibility, attract talent, and establish thought leadership.

Speaking is rare, high-impact — most engineers don't speak publicly. Those who do become visible, credible, authoritative.
Talks are reputation amplifiers — give 30-minute talk to 100 people at conference = reach 100 decision-makers, bloggers, recruiters. Huge return on time.
Preparation time : speaking time is high ratio — 1 hour talk requires 10+ hours prep. Budget time realistically.
Live performance is different from writing — same content, 50% different delivery. Speaking skills are learnable.

Choose topic strategically: Not "we fixed bugs" (too narrow). Look for: novel approach, interesting problem, widely applicable. "Scaling search to millions of documents" is better than "we deployed Elasticsearch."
Create outline, not script: Full script = reading, boring. Outline forces you to speak naturally. Outline: opening hook (why is this interesting?), 3-4 main points (each 5-7 min), conclusion (what can audience do?).
Practice out loud, multiple times: Reading silently, then going live = disaster. Practice 3+ times. Time yourself. Get comfortable with material so you can look at audience, not slides.
Design slides for legibility: Big fonts (36pt minimum). Fewer words per slide (max 10 words). Use images. One idea per slide. Slides support talk, not replace it.
Prepare for Q&A: Anticipate hard questions. Prepare answers. "I don't know, good question" is fine, but prepare for likely ones. Q&A is where credibility is tested.

Reading slides verbatim: Boring. Audience can read faster than you speak. Slides are support, you're the talk.
Too much content: 40-minute talk trying to cover 80 minutes of material. Rushed, stressful. Better: go deep on 3 topics than shallow on 10.
No practice: First live performance = nervous, reads from slides, stumbles. Practice multiple times before. Confidence matters.
Ugly slides: Comic Sans, tiny font, walls of text. Distracting. Spend time on design. Simple, clean, readable.
No clear takeaway: Audience leaves confused what they learned. Every talk needs: "Here's the main insight" and "Here's what you can do with it."
