About
Hey, I'm Leo 👋
I built strongyes.io for the engineer who knows the answer but freezes the second someone is watching. I've been that person. The code was never the hard part — it was staying calm, thinking out loud, and not going blank when it counted.
So strongyes.io is a place to practice the scary part on purpose. Pick a problem, talk through it out loud, get real-time coaching. One rep at a time, until the room stops feeling like a test.
If it helped you walk into an interview less afraid, I'd love to hear about it.
The coaches
Meet Coco and Fin.
Coco
The dog who hears what you meant
Coco is who you start with. She listens to your story, finds the spine, and tells you — kindly — which version actually lands. Then she asks the one question that opens it up.
Fin
The shark who sees the trap
Fin is the harder version, switched on when you want it. He asks for the clarifying question, then the time complexity, then the corner case — and he waits while you find it.
Why they know this stuff
They've heard every interview.
Fin and Coco aren't humans. They aren't former FAANG engineers with war stories. They're animals who happen to have read every transcript, every postmortem, every debrief. Pattern recognition at scale — no ego, no advice from the one interview they aced in 2019.
They aggregate. They don't invent.
What to do next
Check the proof, then decide.
The problem library is where you do a rep. Pricing is where the live coaching offer opens up when you want reps on tap.
Open the problem library and talk through one out loud. That is the whole product.
When you want hosted voice reps with Coco and Fin, the offer is already spelled out on pricing.
