Architectural Core
🌐 API Gateway
Highly available entry point for RESTful requests, managing traffic, routing, and securing backend resources.
⚡ AWS Lambda
On-demand serverless compute executing business logic with sub-second scaling and zero idle costs.
📊 Amazon DynamoDB
High-performance NoSQL database providing consistent single-digit millisecond latency at any scale.
🧠 NoSQL Patterns
Implementation of key concepts like flexible schemas and efficient partition key design for optimized data access.
🛡️ Zero Infrastructure
Built entirely on managed services, removing the need for server provisioning, patching, or maintenance.
🚀 Postman Verified
Thoroughly tested API endpoints ensuring reliable request/response cycles and correct status code handling.
Project Visual Journey
System Architecture
Technical overview of the serverless backend, showcasing the flow from request to data persistence.
DynamoDB Table Design
Configuration of the NoSQL table, including partition keys and capacity settings for efficient data storage.
Serverless Logic (Lambda)
Core backend functions responsible for processing CRUD operations and interacting with the database.
RESTful Orchestration
API Gateway setup defining the endpoints and triggering Lambda functions based on HTTP methods.
API Testing & Validation
Verifying the POST endpoint in Postman to ensure successful record creation in the database.
GET Request Verification
Validating the retrieval of data through the GET endpoint, confirming correct API responses.
NoSQL Data Persistence
Visualizing the live items within the DynamoDB table after successful API operations.
