• Migrated front-end page to React for better performance and future extensibility, and convert original ES5 codes into JSX, and use Babel to transpile code with ES6 new features.
• Built a Single Page Application in React using react-router to navigate and display components without refreshing the website or creating new tabs.
• Redux reducer to control the shared resources between components such as LoggedIn status in store, and used Redux promise as a middleware to handle asynchronous actions
• Implemented different types of forms such as: Login, Sign-up by using redux-form to gather all the form information and implemented custom validator to validate user input before submitting form to back-end.
• Styled the React elements such as input box, form, table, etc using CSS and material-UI
• Implemented RESTful API using axios by sending Redux promise through http request to server side.
• Used Spring Boot to configure server environments and application parameters.
• Configured Java Beans using Java IoC, and used JPA to manage the ORM(Object Relational Mapping) which maps the bean to corresponding database table by using @Entity, @Table, @JoinColumn and @ManyToMany and etc.
• Managed Java Collections using Java 8 Stream API, process data in parallel and gather the result into a Collection for output.
• Used Java 8 Lambda expression to implement functional interfaces.
• Used JPA to generate database query and use Spring MVC to handle different requests and send different responses based on the database query.
• Designed new relational database by using Oracle database and used ER-diagram to demonstrate the relationship between tables.
• Created store procedures for sign-up and add/edit items purpose.
• Implemented Jest test case to run unit test in front-end, JUnit to run tests in back-end and use Selenium to implements automation scripts.
• Deployed front-end and back-end application to AWS S3 and EC2 server.
