Java | SpringBoot | Microservices | Kafka | Redis | JUnit | MySQL | DockerHello, I'm Arunkumar, an experienced Java developer with a year of hands-on experience. I'm passionate about creating efficient and scalable software solutions, and I've had the opportunity to work on a variety of projects that have sharpened my skills across different areas of software development.API Optimization : One of my significant achievements includes optimizing API response time s within an end-to-end work management software. I successfully reduced response times from a range of 5 to 20 seconds down to less than 2 seconds. Leveraging Redis caching and database indexing techniques, I delivered remarkable performance enhancements.Microservices : Developed an order microservice for an e-commerce platform. My responsibilities included data storage, seamless Kafka integration for real-time notifications, and implementing robust retry mechanisms. Ensuring code quality through unit testing and SonarLint analysis was a key part of my role. Unit testing: I'm passionate about testing and quality assurance. I led efforts to enhance test coverage in an audit trail application, achieving an impressive increase from zero to over 90% using Mockito and JUnit frameworks.
