Frontend code
Next js
Reactjs
GraphQL, AWS appsync
Apollo
Typescript
jest for test cases
serverless-stack

Backend code
AWS lambda, Nodejs
Typescript
jest for typescript
aws-sdk
servrelss-stack
apollo
mongoDB
mongoose

This application is written 2 years ago and deployed on AWS. Now AWS has upgraded the node version to nodejs20 to deploy as a result our old project needs to be upgraded and successfully deploy onto AWS.
Both the frontend code and backend code are on GitHub repository with code pipeline setup to deploy on AWS with CI/CD.

You will be given access to the code repos and AWS account. You will be required to setup your local environment and also setup your branch and connect AWS codepipeline to your branch for CI/CD.
