EduPulse — Interactive Cohort Learning & AI Assessment Platform
An interactive education platform supporting cohort-based video courses, automated coding assessment grading, and verifiable credential issuance with sub-second lesson streaming.
Operational Friction & System Constraints
Instructors spent 15+ hours weekly manually grading coding exercises and student assessments, while global video playback suffered buffering on low-bandwidth student connections.
System Engineering & Automation
Built a sandboxed Docker execution environment for instant automated code grading, integrated AWS CloudFront video transcoding with adaptive HLS streaming, and designed interactive live cohort discussion rooms.
Multi-tenant sandbox container runner isolating student code execution with 500ms feedback latency.
