WHAT I BUILT

Joe Speaking

joespeaking.com

An English speaking test simulator with natural conversation, real-world feedback, and a full practice lifecycle — 100× less cost, fully personalized, built by a learner for learners.

I built it for myself first — now it’s yours. My first commercial product. Real users. Real revenue.

WHY I BUILT IT

01

English Was My #1 Barrier

English was the top challenge that stopped me from going abroad. I built it for myself first — then share it with others.

“There are no limits anymore. Anyone can do anything. The only limiting factors are agency and ambition.

Never has a college degree, work experience, network, even the accumulation of knowledge been worth less.

You can just ship things.”
@RAUCHG

It’s time to build!

Building a real product is still challenging.
The bottleneck is no longer the code itself.

WHAT’S NEXT

Currently working on:

  • WebRTC migration + state machine refactor for real-time connection reliability
  • Goal: build the best natural conversation English standardized test experience in this domain
  • A live example of using AI to solve our own problems in a niche domain that generic tools can’t match

“Being responsible to my real users who trusted me with their money.”

It’s just a start.

Thank You
