ABOUT ME
I am an experienced Java developer with over 3 years of professional experience in creating and maintaining scalable applications. I have deep knowledge in servlet development and Java application programming, as well as experience working with popular frameworks such as Spring (including Spring Boot, Spring Cloud, and Spring Security).I specialize in microservices development and am skilled in designing and integrating RESTful APIs.
I confidently utilize CI/CD tools such as Jenkins and GitLab CI/CD, and have experience with containerization (Docker) and orchestration systems (Kubernetes). I am also proficient with both relational and non-relational databases, including PostgreSQL, MySQL, and MongoDB
I actively use messaging tools such as RabbitMQ and Kafka, and I adhere to Agile/Scrum methodologies, which enable me to work effectively in teams and adapt to changes.
In addition to technical skills, I value the importance of communication and collaboration within a team and am always ready to share knowledge and experience with colleagues. My goal is to create reliable and high-performance solutions that deliver value to users and the business.
