Talk for 60 seconds.
He'll have notes.
He counts your ums. He tracks your WPM. He quotes your own words back at you with timestamps. Not to be mean — he just wants you to get better. He's very invested.
Recent Observations
ChatGPT is your friend. He is your coach.
Friends don't tell you that you said "like" fourteen times. Friends are polite. Your sea lion is not.
- Lets you pause, restart, and re-record. No pressure. No stakes. No growth.
- Auto-cleans your transcript. Your "ums" disappear. So does your chance to fix them.
- "Great job!" — a lie, but a polite one.
- 60 seconds. No restarts. Real pressure, like the real thing.
- Preserves your exact words, timestamps, and every hesitation.
- Quotes you. Scores you. Gives you one thing to fix. Then waits.
One drill. 60 seconds. He'll do the rest.
He picks a prompt
Curated tracks or your own custom deck. No warm-up. No prep time. He doesn't believe in warm-ups.
“Design a distributed rate-limiting architecture spanning 5 global cloud regions.”
You talk. He listens. He judges.
Speak until the timer runs out. He's counting your pauses. He's counting your fillers. He's counting everything.
He delivers the verdict
Quotes you. Scores you. Hands you one micro-drill and expects you to actually use it. He'll know if you don't.
Two tracks. He has opinions on both.
System Design & Architecture
For interviews, design reviews, and explaining yourself under pressure. He knows what good looks like.
“Explain what a Load Balancer is and why it's critical for scale.”
“Design a distributed rate-limiting architecture spanning 5 global cloud regions.”
Impromptu & Executive Speech
Behavioral questions, toasts, pitch practice, or just getting better at thinking out loud.
“Describe a project trade-off where you had to compromise on scope.”
“Convince an audience that privacy is more valuable than user convenience.”
This is what he sends back.
Your words. His notes. Timestamps included, because he wants you to be able to find the exact moment everything went wrong.
“Design a distributed rate-limiting architecture spanning 5 global cloud regions.”
“...I'd probably use Redis for that...”
You named a tool without explaining why. He would like you to state the failure mode first.
“The first question I'd ask is what's our SLO...”
Correct instinct. He's not easily impressed, so take the win.
Lead with the constraint before the solution. Practice a 15-second cold open naming the multi-region sync issue, then specify Redis or Memcached. He'll check.
He works for credits. Or Pro.
Free users get 3 coaching credits a day. Pro users get unlimited attention, which he prefers.
3 credits/day · refills at midnight UTC
Flexible month-to-month access. Cancel anytime.
