• Utilized AWS services (EC2, S3, RDS, Lambda, SQS, SNS, Auto Scaling) to deliver scalable and robust cloud-based solutions, enhancing system reliability.

• Administered MySQL databases to optimize data storage, retrieval, and ensure data integrity, boosting performance by 15%.

• Used Kotlin to develop SOAP web services with WSDL, improving inter-service communication while maintaining backward compatibility with Java-based systems.

• Integrated Hibernate ORM to ensure efficient database interaction and reliable data persistence.

• Developed responsive user interfaces using HTML5, CSS3, and TypeScript. Leveraged Angular for front-end and Node.js for back-end development in single-page applications.

• Employed AJAX for asynchronous data fetching and real-time updates, improving web application responsiveness.

• Designed and implemented Data Access Objects (DAO) to abstract data access logic, simplifying database operations.

• Secured web services through the implementation of JWT for authentication and authorization.

• Automated build, testing, and deployment pipelines with Jenkins and Maven for continuous integration and delivery, reducing manual effort by 30%.

• Conducted unit testing with JUnit and adhered to test-driven development (TDD) principles, elevating code quality and reliability.
