# CRUD DynamoDB Serverless App
This project is a complete Serverless CRUD API built using **AWS SAM (Serverless Application Model)**, **Node.js**, and **DynamoDB**. It's designed for learning and demo purposes, showcasing how to build, test, and deploy a serverless backend on AWS.
---
## ✅ Features
- Create, Read, Update, Delete (CRUD) APIs
- Powered by **AWS Lambda**, **API Gateway**, and **DynamoDB**
- Local testing with `sam local`
- Deployed using `sam deploy --guided`
