Experience
Computer Science and Software Engineering Educational Platform
It is backed by a .NET back end hosted on Amazon EC2 instances that receive requests through Amazon API Gateway. It acts as a load balancer and a gateway for request and response transformations.
The database used is Amazon RDS. The application is a single-page application (SPA) developed using React and hosted as a static website on Amazon S3.
It uses Amazon Cognito for the authentication and authorization services and utilizes Amazon's content delivery network (CDN) using Amazon CloudFront distributions for reducing latency in serving geographically distant requests.
A CI/CD pipeline is used in development when making deployments using AWS CodeBuild and AWS CodePipeline.
Social Event Planner
For the sake of scalability, the command query responsibility segregation (CQRS) pattern is used alongside the mediator pattern to distinguish between reading and writing operations for read-optimized and write-optimized databases accordingly.
This single-page application (SPA) developed in React uses MobX for state management and Axios to send requests to the REST endpoints. The application also includes a real-time chat feature implemented using SignalR.
eCommerce Platform
The project involves the actual platform with product searches, a fully-featured shopping cart with PayPal and credit/debit card payments, and a product rating and review system. Additionally, an admin area was created to manage customers, products, and orders.
