Let's Learn — Huynh Thanh Nam

Overview

A classroom management platform for teachers and students — courses, assignments, quizzes, live meetings, and collaborative whiteboards. Built as four services orchestrated with Docker Compose.

Architecture

Next.js UI  ──►  Spring Boot backend  (topics, quizzes, assignments)
     │
     ├──►  LiveKit server (Go)     — real-time video & meetings
     └──►  tldraw server (Node.js) — collaborative drawing rooms

Stack

Next.js, TypeScript, Spring Boot, Java, Go, LiveKit, Node.js, tldraw, Docker Compose.

Highlights

Learning workflows. Topics, quizzes, assignments, and dashboards wired through the Java backend.
Real-time collaboration. LiveKit for live sessions; tldraw for shared boards and room management.
Multi-service local dev. docker-compose up brings up backend, media, drawing, and UI together.
UI coverage. Calendar, course overview, dashboard, and in-quiz flows documented in the repo.

What I'd do differently

Add OpenAPI-generated TypeScript clients instead of hand-typed API calls across services.
Centralize auth/session propagation across the Go and Node sidecars.
