Building strong backend fundamentals → Creating real-world systems → Teaching backend concepts
This repository represents my backend development journey — starting from scratch and progressing toward building scalable, production-ready applications.
It is the foundation layer where I implemented and understood all core backend concepts before moving to advanced projects.

- Client-Server Architecture
- Request-Response Cycle
- REST API Design Principles
// Express server setup
const app = express();
app.get('/users', getAllUsers);
app.post('/users', createUser);
app.put('/users/:id', updateUser);
app.delete('/users/:id', deleteUser);Middleware acts as a bridge between request and response.
// Custom middleware example
const authMiddleware = (req, res, next) => {
// authentication logic
next();
};- Custom middleware
- Authentication flow basics
- Error handling
// MongoDB connection
mongoose.connect(process.env.MONGO_URI)
.then(() => console.log('DB connected'))
.catch((err) => console.error(err));- MongoDB connection
- Mongoose usage
- Schema & model design

After mastering these concepts, I built a full production backend system:
| Feature | Details |
|---|---|
| 🔐 Auth | JWT — access & refresh tokens |
| 📹 Upload | Multer + Cloudinary integration |
| 💬 Social | Comments, likes, subscriptions |
| 🎵 Content | Playlist & dashboard system |
| 📈 Scale | Clean, scalable architecture |
After building real-world projects, I structured and explained backend concepts as a bootcamp:
- ✅ Backend fundamentals from scratch
- ✅ Real-world architecture patterns
- ✅ Best practices & code quality
- ✅ Interview-focused backend concepts
| Technology | Purpose |
|---|---|
| Node.js | JavaScript runtime |
| Express.js | Server & routing |
| MongoDB | NoSQL database |
| Mongoose | ODM for MongoDB |
| dotenv | Environment management |
| Nodemon | Development server |
git clone https://github.com/iamanu26/backend-learning.git
cd backend-learning
npm install
npm run dev- ✅ Strong backend fundamentals
- ✅ Clear understanding of APIs
- ✅ Database design thinking
- ✅ Scalable project structuring
- ✅ Confidence to build production-level backends
This repo is where I learned backend. The YouTube backend is where I applied it. The Bootcamp is where I taught it.
