Case Study
Replacing Zoom with a purpose-built teaching platform for a major EdTech company
Client
A large EdTech company
Industry
EdTech
Duration
6 months to release (ongoing)
Team
4 developers (2 React Native + 2 Java)
The challenge
Zoom wasn't built for teaching. Their teachers needed something that was.
The client had thousands of teachers delivering live classes through Zoom. It worked at first, but teachers couldn't share interactive exercises, track student engagement in real time, or integrate with the company's existing curriculum platform. Students would mute themselves, turn off cameras, and drift. Teachers had no tools to bring them back. The company needed a custom platform that treated live classes as an interactive experience, not a video call.
Our solution
Two mobile engineers and two backend engineers, embedded in their product team
We placed four developers directly into the client's existing product organization. Two React Native engineers worked on the student and teacher mobile apps. Two Java engineers worked on the backend services: real-time session management, exercise delivery, engagement tracking, and integration with the existing curriculum API. We used Firebase Realtime Database to speed up real-time feature development, and Agora SDK for the video streaming layer. Our engineers joined the client's standups, used their tools, and followed their processes.
