Good day!

My name is Ruslan, I am a Full Stack developer with experience in backend development using Java and frontend development using JavaScript. During my professional career, I have worked with corporate web applications, REST APIs, and the full development cycle—from implementing business logic and working with databases to integrating with the client side.

I have practical experience in backend development using Java and Spring (Spring MVC, Spring Security, Spring Data JPA), working with Hibernate/JPA, designing RESTful APIs, optimizing SQL queries, and interacting with MySQL. I have a good understanding of security principles, caching, and scaling server solutions.

On the frontend side, I have worked with JavaScript, HTML5, CSS3, jQuery, as well as with SPA approaches. I have experience integrating the frontend with the backend through AJAX and REST, working with server-side templating, and responsive design.

I am also familiar with modern development infrastructure: Docker, CI/CD processes, working with cloud services, and database migrations. I feel comfortable in team collaboration, participate in code reviews, and am focused on code quality and stability.

I am interested in your vacancy due to the combination of working with a large production product and the opportunity to modernize the existing system. I believe that my experience and approach to development can be beneficial for your team.

I would be happy to discuss collaboration and answer any additional questions.

Sincerely,
Ruslan
