•Designed and developed java springboot based cloud-native microservice applications and deployed and hosted them on Pivotal Cloud Foundry(PCF). Worked with Java 8, Java 11 and Java 17 to ensure efficient and optimized performance.•Experienced in developing applications from scratch using SpringBoot, SpringBatch, SpringMVC, Spring Cloud frameworks. •Optimized existing solutions by developing new features and reducing server load. Developed reusable and scalable code to enhance functionality and improve performance.•Extensively worked on leveraging Java Collections like HashMaps, ArrayLists, Sets and Java8 features such as streams, lambda functions to improve efficiency and to manipulate data. Implemented proper exception handling and multi-threading solutions to optimize resource utilization. •Utilized RabbitMQ for implementing asynchronous messaging and Redis for caching. •Experienced in creating and consuming REST APIs using SpringBoot Rest Template and SpringCloud Open Feign Client for fetching and posting data. Implemented authentication and authorization using Spring Security, OAuth2 to ensure secure data access and to enhance overall application security. •Implemented Swagger UI to enable developers to test and interact with APIs in a user friendly, intuitive interface. Utilized Postman and Insomnia for testing REST APIs. •Integrated Spring JPA, IBatis, Hibernate, Spring JDBC for object relational mapping and to perform database CRUD operations.•Ensured the applications had 70% code coverage by writing Junit tests using Mockito framework. Used SLF4J and LOG4J frameworks for logging.•Automation of GIT Scripts and setting up of Scheduled jobs in PCF.•Responsible for creating documentation on the application design, development strategies and testing procedures for future replication using Confluence.•Actively participated and involved in SCRUM standup calls as well as Sprint Planning sessions and Sprint Grooming sessions as per AGILE methodology.
