Confidential, Redwood City, CA

JS Full-Stack Developer

Responsibilities:

• Designed and implemented a full-stack web application using MongoDBExpressJSReact/ReduxNodeJS (MERN) stack.
• Used MongoDB to build the database for storing the application’s data.
• Used NodeJS Express to build the back-end server and implemented many back-end APIs as well as connected it to the MongoDB database.
• Used Json Web Token (JWT) and passport-jwt to build the Authentication and Validation functionalities of the web application.
• Used axios module to send http request to back-end APIs.
• Used ReactJSand react-router to build Single Page Application and for page navigation.
• Used Props as the approach to one-way passing the data from parent Component to child Components.
• Designed and optimized states to store necessary data for each stateful Components.
• Created Redux store and reducers to store the data that eliminates the cons of one-way data binding in ReactJS.
• Worked on action creator for creating actions which can be an asynchronous HTTP request made by Axios library.
• Applied Redux-thunk middleware to the store that helps redux deal with actions which could be a function instead of an object.
• Used ExpressJS to set up the HTTP server that deals with the logic of RESTful request with different endpoints and tested with Postman.
• Linked MongoDB to HTTP server using Mongoose driver which could create, read, update and delete (CRUD) data in the database.
• Implemented unit test to test reducers and action creator in Redux using JavaScript test library.
• Used HTML5/CSS and Bootstrap to build user-friendly front-end UI for users.
