Full-Stack Developer

Responsibilities:

• As a member of Agile Development Team to develop a Single Page Web Application based on React.js for front-end, Spring Boot for back-end and MS-SQL for database.
• Developed RESTful API used for managing data with Spring Boot.
• Involved in the development using Java/J2EE Technologies, Web Services and Hibernate ORM Framework.
• Used Spring AOP to maintain clean code and used pointcuts to call other classes methods according to Advice
• Used Maven Project to deal with different dependencies, inherited from JPA Repository and use HQL and Criteria API to implement CRUD operations
• Implemented the JSON Web Token(JWT) in back-end, explicit the user’s identity.
• Separated the project into different layers such as Controller, Service, Dao, Entity, Security. Implement different requirements in different layers like developing different POJO classes to map corresponding tables in MS-SQL and also implementing the relationship by using OneToMany or ManyToOne annotation.
• About the security, implemented authentication with JWT, if successfully authenticated then stored the JWT in local storage. Also, hashed the user password before stored it into database
• Implemented Unit test for both front-end and back-end.
• Created UI by using JSX and Bootstrap, also used Font-Awesome to decorate it.
• Used stateful classes to perform From Validation with JSX to make sure the input value is suit for the requirements.
• Used Route, Redirect from react-router-dom library to convert components to each other, also design the Router Guard to restrict accessibility for each component
• About the communications with components, used Props and State, also applied the Redux to create to global states shared with every component.
• Used Redux-Thunk to execute asynchronous code such as http request.
• Utilized Axios to send http request to API and the error handling. Used Interceptor to set the JWT header to improve the efficiency
• Used Git for version control and JIRA to track the progress of the project

Environment: Java 1.8, Sprint Boot, Hibernate 4.0, Junit, Maven, SQL-Server 2017, Azure studio, React.js, HTML5, CSS3, JavaScript ES6, GIT, and Postman.

• Created the Service to share logic and data across Components.
• Used structure directives like NgIf to dynamically change the DOM and attribute directive like NgClass to dynamically get the CSS.
• Used JSON Web Token(JWT ) for authentication, stored the JWT in local storage after successful login and used for auto-login, also used the intercept to get the header to simplify the code
• Used Http Client Module for sending requests to back-end, used Observables, RxJS pipe function and RxJS operators to manipulate the response data which are asynchronous.
• Used Bootstrap3/4 and Media queries to make responsive web behaviors which make the application fits different devices such PC or mobile phone
