One thing I've realized while building projects is that quality matters far more than quantity. Instead of creating another basic CRUD application, I wanted to build something that introduced me to concepts I'd only read about—serverless computing, event-driven architecture, and cloud infrastructure.
That's how I ended up building an Intelligent Polling & Service Monitoring System.
The idea is simple: a user creates a poll by entering a URL along with a polling frequency and duration. From there, the system takes over—scheduling requests, monitoring the service, storing performance metrics, and updating the dashboard automatically.
What made this project interesting wasn't just the functionality, but how it was built.
Instead of handling every request synchronously, I used Amazon SQS and AWS Lambda to process monitoring tasks asynchronously. This made the application more scalable and resilient, especially when multiple monitoring requests are created at the same time.
Security was another area I wanted to explore. The application follows a 3-tier architecture inside an AWS VPC, with the React frontend exposed to users while the backend services and database remain protected inside private subnets.
To make deployments repeatable, I provisioned the infrastructure using Terraform, which reinforced the importance of treating infrastructure just like application code.

- React.js
- Node.js
- Amazon API Gateway
- AWS Lambda
- Amazon SQS
- Amazon DynamoDB
- Amazon VPC
- Terraform
This project wasn't about building the biggest application—it was about understanding the design decisions behind modern cloud-native systems. Every feature gave me a chance to learn something new, and that's what made this project worthwhile.
I'd love to hear your thoughts or suggestions on how this architecture could be improved!
