PROFESSIONAL EXPERIENCE

Confidential, IL

Java Fullstack Developer

Responsibilities:

• Participated in the design, development and support phases of the Software Development Life Cycle (SDLC).
• Responsible in designing, developingMicro-services that are highly scalable, fault tolerant usingSpring Boot and various spring frameworks.
• Developed the front-end user interfaces in Angular 2 that will be integrated using Spring Boot Framework.
• Developed data insertion forms and validated them using Angular2 reactive forms feature and used Bootstrap to apply different styles to the layouts for varying screen sizes and pixels.
• Used Spring Boot because it is radically faster in building cloud Microservices and develop spring-based application with very less configuration.
• Complex features of the Application like timecard grid is implemented using this Microservices architecture.
• Secured the REST services using Spring Boot Framework and created documented REST services using Swagger and Jersey.
• Configured Spring security in the application with LDAP Template and provide access controls using Spring security annotations based on user roles.
• Worked on data persistence by object/relational mapping solution via Hibernate ORM for application save, update, delete operations.
• Involved in injecting dependencies into code using spring core module concepts like IOC of Spring Framework with Spring 4 annotations and AOP.
• Implementation of Docker, and various Docker orchestration tools such as docker -compose, docker swarm and various other management tools.
• Converted our micro-services application to Docker Containers to allow portability and reduce the deployment time.
• Created Angular 4 reusable components using services, injectors and dependencies to avoid front end components to communicate with servers and delegate such tasks to services which makes code robust.
• Created services with Angular 4 @injectable property, as to make the service available for dependency injection when creating components.
• Used Java 8 features like Lambda expressions for array operations, collections and Enhanced concurrency methods throughout the applications for well-defined programming.
• Communicating between component class properties for iterations, filtering and validating form inputs using @input and @output.
• Involved in core cluster setup using Docker and Rebuilt of entire existing bare metal platform over to Docker containers.
• Involved in working, updating and closing the tasks created in GIT and Implemented continuous deployment system with Jenkins.

Environment: Java 1.8, Angular 2/4, Spring boot Framework, Hibernate, Apache Tomcat, WSo2, Log 4j, Swagger, LDAP Oracle, GIT, STS, Maven Windows 7 and UNIX.
