What server-side programming languages do you have expertise in?

I have expertise in Java. I have been working with Java for over 5 years and have developed various server-side applications using Java. I am comfortable with frameworks like Spring and Hibernate. I have also worked with RESTful APIs and have a good understanding of how to design and implement them. Additionally, I have experience with unit testing using frameworks like JUnit.

I have extensive expertise in Java, having worked with it for more than 5 years. In my previous role as a Senior Software Developer at XYZ Company, I led a team in developing a highly scalable and efficient e-commerce platform using Java and the Spring framework. This platform successfully handled thousands of concurrent users and significantly improved the company's online sales. I have also utilized Hibernate ORM for database connectivity and optimization. In addition, I have experience in developing RESTful APIs following best practices and have used technologies like Swagger for API documentation. I have a strong understanding of unit testing and have implemented test-driven development (TDD) in my projects using JUnit and Mockito.

I have a comprehensive expertise in Java, with a track record of successfully delivering high-quality software solutions using this language. For example, in my previous role as a Senior Software Developer at XYZ Company, I led the development of a microservices-based architecture using Java and Spring Boot. This architecture allowed for seamless scalability and high availability of the application, resulting in a 50% increase in user satisfaction and a 30% reduction in response time. To optimize the application's performance, I implemented caching mechanisms using Redis. I also have experience with cloud services like AWS, where I deployed the application on Elastic Beanstalk and configured auto-scaling. Additionally, I am familiar with containerization using Docker and orchestration with Kubernetes. I have worked with version control systems like Git, ensuring the integrity and collaboration of codebase. My expertise also extends to writing clean and maintainable code, following industry best practices, and utilizing CI/CD tools. Overall, my extensive knowledge and experience with Java make me well-equipped to tackle any server-side programming challenges.
