Utilized Node.js's event-driven architecture to write scalable applications, capitalizing on multiple tools and modules by npm for easier debugging and popular testing frameworks such as Mocha

Used OpenAPI to create a user configuration file for providing seamless user experience

Customized Mocha’s testing report, allowing for flexible and accurate reporting of tests for easy reference to individual tests, saving developers time and removing the need to run tests multiple times to see the output for each specific case

Leveraged Express instance for code introspection to look through the server object to create a configuration file

Implemented recursive algorithm to traverse nested request body object that generates configuration file

Applied Mocha/Chai/Supertest testing tools for its flexibility to pair with any testing framework to generate server testing cases

Utilized JSDoc to auto-generate documentation for functional javascript code to allow developers to contribute more easily

Applied Travis CI to ensure that unit tests are run against new features and to ensure new code is automatically and consistently tested for errors

Applied React Context API and React Hooks API to simplifies components by making them flatter and more explicit, enabling faster component re-rendering on updates to state and cleaner code

Utilized Node.js Express library to build a scaling retrieval structure, generating, and responding to user facing application

Implemented JWT to ensure secure transmission of encrypted data for authentication persistence and better user experience

Implemented React Router to minimize server requests and increase load speed by declaring particular routes and components

Integrated WebSockets into Node.js backend and React frontend to establish user-to-user communication in rooms for efficient

Refactored existing code base to add the functionality of multiple rooms to chat for many users

Facilitated communication between Data Science and Software Engineer Team to accelerate product development smoothly
