• Core java | J2EE | SpringBoot | RestFul API | Spring DataJPA | Spring Security | Maven | Weblogic Server | LDAP | Microservices | Hibernate | Angular | Design Patterns | Swagger API Documentation | Postman• My responsibilities range from database design and query optimization to deploying applications on WebLogic servers and following Agile methodologies to ensure timely delivery and alignment with business goals. • Experienced in the software development life cycle, application setup, bug fixing, and application support.• Deployed high-quality, reliable, and secure backend solutions that meet the requirements and expectations of stakeholders. • Analyzed the performance of APIs to identify bottlenecks and areas for improvement. Focused on reducing processing time, optimizing database queries, and minimizing payload sizes.• Implemented pagination in API responses for handling large datasets. This significantly reduced the size of API responses, improving load times by approximately 30%. • Utilized Java 8's Stream API to process large data collections efficiently, ensuring faster data manipulation and filtering.• Configured Lightweight Directory Access Protocol (LDAP) for secure and centralized authentication and authorization within the application. Achieved 85% improvement in compliance with organizational security policies by centralizing user credentials and access management.• Integrated SSL/TLS certificates to enable HTTPS, ensuring encrypted communication between the client and server, protecting data from interception.

• Core java | J2EE | SpringBoot | RestFul API | Spring DataJPA | Spring Security | Maven | Red Hat OpenShift Server | Kafka | Microservices | Hibernate | Postman• Developed RESTful Web Services using Spring Boot to integrate multiple systems and streamline data flows.• Responsible for developing and maintaining the account management system. This involved implementing the core functionalities such as deposit, withdrawal, and balance retrieval.• I ensured data integrity and consistency by utilizing ConcurrentHashMap to handle concurrent access and updates to account balances.• I addressed potential issues such as NullPointerExceptions, race conditions, insufficient balance, and lost updates through careful error handling and synchronization mechanisms• By incorporating pagination with the stream API,effectively achieved a substantial 30% reduction in API response time.• Troubleshot and resolved bugs and issues, resulting in a 25% reduction in customer complaints.• Developed and implemented robust data validation strategies in Spring Boot applications, ensuring the integrity and security of user inputs.• Implemented both custom and global exceptions to enhance the reliability and stability of the system. • As part of implementing the search functionality for transaction management, my responsibility was to ensure that users could efficiently retrieve transactions based on specified criteria.• Involved in designing and implementing a search API that could handle various input parameters such as date ranges, transaction types, and other filters.• Focused on optimizing the search process to handle large datasets effectively, for which it takes less response time for retrieval of transaction records using spring Data jpa & pagination.• Experience on development/deployment , application setup and bug fixing and supporting application.

• Core java | J2EE | SpringBoot | RestFul API | Spring DataJPA | Spring Security | Maven | Hibernate | Postman• Collaborated with frontend developers to define API specifications and ensure seamless integration between frontend and backend systems.
