We help:

• 🇧🇷 Brazilians
• who want an American accent (or closer to it)
• and already speak English at an advanced level

This GitHub organization powers our internal development, including:

A private app where clients access annotated, interactive feedback and personalized training tools.

As of March 27, 2025:

• Frontend
  • React, Zustand, shadcn/ui
• Backend
  • Node.js (Express), hosted on Render
  • Airtable → migrating to PostgreSQL (Prisma)
  • AWS S3 (audio + JSON)
• Other
  • Auth0 for authentication
  • Manual/informal testing
  • 🦆 Rubber ducking + Cursor, ChatGPT, dev friends

Coming Soon:

• Native mobile apps (React Native via Expo)
• AI/ML (but keeping human expert in the loop for important client feedback)
• More rigorous statistics and measurement of accent
• More structured testing + deployment

We're also building tools for:

• Client progress tracking
• Funnel + content performance
• Business metrics
