React/UI Developer

Responsibilities:

• Followed test driven development approach for developing the components of our application.
• Redux is our state management library to help behave application consistently, and also run in different environments
• Application front-end is built on top of React.js library and effectively utilized all its features in avoiding the performance bottlenecks
• Worked on Redux and ngRX store to manage the State, Subscribing and unsubscribing the state changes and dispatching the actions in Angular 2/4.
• Worked on React.JS components, Forms, Events, Keys, Router, Animations and Redux concept.
• Worked on React JS Virtual Dom and React views, rendering using components which contains additional components called custom HTML tags.
• Extensively used Redux-saga library to manage side-effects within the system and to perform asynchronous calls using generator functions in ES6 and to access browser cache.
• Made use of redux saga middleware to access redux application state and dispatched redux actions.
• We are a scrum team and followed Agile methodologies. Attending the daily scrum is one of our primary responsibility
• JIRA is our defect tracking board, we update and move forward in our project only through this.

Responsibilities:

• Writing declarative, efficient, and flexible JavaScript code using React.js library for building user interfaces.
• Redux with ducks for making action-creators and reducers.
• Used redux Saga that aims to make side effects (i.e. asynchronous things like data fetching and impure things like accessing the browser cache) in our application easier and better.
• Webpack for building the frontend.
• Followed test driven development approach for developing the components of our application.
• Components were created keeping in mind to use them where ever we find the similar functionality.
• Avoided writing business logic inside the component which reduces readability, whole business logic was implemented inside the reducers.
• Made Ajax calls to make the service calls to the backend.
• Used Postman to know the API development workflow.
• Imported and used libraries like Lodash to increase the code efficiency.
• Integration with backend and testing environments to perform the Dev testing before delivering it to QA.

• Imported React-Bootstrap library to reuse built in components like Modal, Navbar.
• Writing test cases using Jest framework.
• Leveraged LESS as the preprocessor to manage and build application styles.
• Used GIT as our version control system.
• Implemented Apache Tomcat Maven Plugin which provides goals to manipulate WAR projects within the Apache Tomcat servlet container.
• As a part of scrum team attended the daily stand up meetings to provide the status and ETA for the tasks that are in progress.
• JIRA is the issue & project tracking board that we have used in our project.
• We have bi-weekly sprint as apart of which both development and testing that story must be completed without any bugs pending.
• Performed smoke testing on the application before each release from the dev side.
