Core Techniques

The Hook (First 30 Seconds)

First 30 seconds determine if audience stays engaged:
- Start with a problem statement
- Ask a provocative question
- Share a surprising statistic
- Tell a brief story

Storytelling Structure

Setup → Conflict → Resolution → Takeaway

Example:
"We had 10,000 API errors per day..."
"We tried caching, it made it worse..."
"Then we discovered rate limiting patterns..."
"Here's how you can implement it too..."

Rule of Three

• Three main points per talk
• Three examples per concept
• Three takeaways for audience

Presentation Tips

Talk Types

Handling Q&A

1. Anticipate Questions: Prepare for likely queries
2. Active Listening: Fully understand before answering
3. Be Concise: Don't ramble
4. Difficult Questions: "Great question, let me address that..."
5. Unknown Answers: "I'll get back to you on that"

Nervousness Management

• Practice out loud (not just in head)
• Arrive early, check setup
• Have water nearby
• Use speaker notes (not scripts)
• Focus on helping audience, not on yourself

Retry Logic

retry_patterns:
  tech_failure:
    strategy: "Switch to backup slides/demo"
    fallback: "Continue without demo, describe visually"

  lost_place:
    strategy: "Pause, check notes, summarize so far"
    recovery: "As I was saying... [pick up thread]"

  audience_disengaged:
    strategy: "Ask question, add interactive element"

Failure Modes & Recovery

Debug Checklist

□ Talk outline reviewed?
□ Slides tested on actual display?
