LearnLink
LearnLink is a global educational marketplace facilitating high-quality live interactions between students and tutors. By integrating interactive whiteboards with low-latency WebRTC video, it provides a classroom experience that transcends geographic boundaries.
Specialized tutoring was traditionally difficult to find and required students to commit to expensive, long-term subscriptions. Poor technical infrastructure often resulted in high video latency and a lack of interactive tools, hindering effective global knowledge transfer.
We engineered a pay-per-session marketplace with a custom WebRTC bridge ensuring sub-500ms latency. A shared interactive canvas enables real-time collaboration, while an AI-driven bidding system matches students with tutors based on specific skill gaps and budget.
Challenges
Low-Latency Video Delivery
Ensuring sub-second video lag across continents for a real-time classroom feel.
Interactive Canvas Sync
Maintaining perfect synchronization of drawing and text input on the shared whiteboard between student and tutor.
Automated Tutor Bidding
Developing a fair, high-speed matching engine that connects students with the best-fit tutors based on budget and skill.
Our Solutions
We developed LearnLink as a high-density educational marketplace. The core is a custom WebRTC integration that delivers sub-500ms latency for global video classes. We built a shared interactive canvas using Canvas API and WebSockets for real-time pedagogical collaboration. The backend, powered by Node.js and PostgreSQL, handles complex bidding and scheduling logic with high accuracy. We implemented a multi-layer escrow system for secure payments and used cloud-native video processing for automated lesson recording. The result is a friction-less EdTech ecosystem that empowers tutors and students worldwide.
