ABOUT THE CLIENT
Our client’s global idea was to build education app for language learning called Duals. The platform aims to help people learn languages and accents by connecting them with native speakers or certified teachers for video lessons. The points teachers earn from teaching students can also be used to learn other languages.
Challenge
The primary challenge was to engineer a high-performance cross-platform MVP in under three months, integrating complex Twilio video infrastructure and custom backend logic while maintaining a seamless, high-engagement user experience.

Business Results
Leveraging a high-performance technology stack of TypeScript, React Native, Twilio, and Firebase, our team successfully launched fully functional applications for both iOS and Android.
