-I spent over 2.6 years at Samsung SDS as a Java Backend Developer. My main focus was on architecting and building highly scalable systems using Java and Spring Boot.-I actively contributed to critical back-end projects like the HRMS and Billing Cycle Management Systems. This hands-on experience gave me a solid grasp of Microservices architecture, designing RESTful APIs, and workflow automation.-A key accomplishment is implementing the caching and performance optimization with Redis, which greatly improved system response time and reduced the burden on the database.-Good at Data Structures and Algorithms, hands-on experience in solving coding challenges, improvement of problem-solving skills.
