Computer Science and Software Engineering Educational Platform

This encyclopedia and educational platform for the domain of computer science and software engineering is still under development. Its infrastructure uses the AWS Cloud Development Kit (AWS CDK) in TypeScript to generate the necessary AWS CloudFormation templates.

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

The social event planner is a web application that follows the clean architecture model when building a REST API using .NET Core.

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

An eCommerce platform built using the MERN stack where I was the full-stack software developer working across the stack.

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.

Homestay Marketplace

A NestJS-based app for booking stays at a hotel or hostel. Developed in TypeScript, achieving dependency injection by using NestJS's module architecture and models the app's data using TypeORM entities and relationships.
