JustCall - reliable voice practice
A voice-first language-practice product with a React Native app, authenticated TypeScript backend, real-time AI conversation, and explicit session-reliability safeguards.
- Problem
- A useful speaking product needs more than a working voice SDK: the learner must be authenticated, the microphone and provider lifecycle must stay predictable, and later feedback must remain tied to the correct conversation evidence.
- Approach
- Use attempt identity, cancellation, request deadlines, and provider cleanup to prevent late async work from reopening an ended call.
