I built an Enterprise-grade LMS backend with NestJS 11 & Notion API (and I’m sharing the blueprint)

#nestjs #typescript #backend #webdev

Hey everyone 👋,

As a developer, I always found it frustrating to use platforms like Teachable or Kajabi for my courses. They are expensive, rigid, and honestly, the text editors suck. Since I already organize my entire life in Notion, I thought: Why not use Notion as a headless CMS for an LMS?

So, I spent the last few months building Nexus LMS — an enterprise-grade backend architecture from scratch.

🛠️ The Stack (Built to be bulletproof):

Backend: NestJS v11 (Node.js)
Database: PostgreSQL + Prisma 7 ORM
Security: JWT Authentication & Role-Based Access Control (RBAC)
Content: Dynamic sync with Notion API (write in Notion -> updates the course instantly)
Infrastructure: Fully Dockerized, ready for Google Cloud Run / AWS

Instead of just keeping it to myself, I polished the codebase, added strict end-to-end type safety, integrated a seamless Swagger UI, and packaged it as a template to save other devs ~400 hours of boilerplate setup.

🥷 The Distribution (Anti-Piracy Bot)

I also built a Telegram bot to handle distribution via crypto/fiat. To prevent piracy, the bot delivers the codebase with a 15-minute self-destruct timer and anti-forwarding protection.
