PodCast App

Overview

An educational platform that combines video lessons, coding assignments, and community interaction. It tracks student progress, automates assignment grading, and provides a seamless learning experience.

Problem

Building real-time audio communication from scratch involves complex WebRTC signaling, room management, and recording workflows. Managing access control and participant limits adds additional complexity.

Solution

I built a live meeting platform using LiveKit for real-time audio streaming, combined with a custom backend for meeting lifecycle management, access control, and recording metadata handling.
