EdTech: Scaling Real-Time Interactive Classrooms

E.G needed to replace a third-party classroom tool (which was expensive and limited) with an in-house solution. The challenge was syncing the whiteboard drawing state across 50 students in real-time with low latency.

GTEMAS provided 3 Senior Frontend Engineers specialized in WebSockets and Canvas API. We built a custom whiteboard engine using operational transformation (OT) to handle concurrent edits. We integrated WebRTC for high-quality, low-latency video streaming directly within the browser.

Owning the classroom tech allowed E.G to launch unique features (like AI-based attention tracking) that competitors couldn't match, driving a 30% increase in enrollments.
