    As an accomplished full-stack software developer, I bring expertise in a wide range of technologies to deliver exceptional web applications. With a strong foundation in HTML, CSS, and JavaScript, I create visually appealing and interactive user interfaces. Combining this front-end proficiency with my deep knowledge of Java, Spring Boot, Spring Security, and Spring JPA, I build robust and secure back-end systems that handle complex business logic. To ensure seamless data management, I am well-versed in MySQL and possess hands-on experience with Hibernate for efficient ORM (Object-Relational Mapping). This allows me to design and optimize databases for maximum performance and reliability. From developing RESTful APIs to integrating third-party services, I am adept at leveraging these technologies to create scalable and extensible solutions. In addition to my development skills, I have a strong background in testing. I am proficient in both automation and manual testing methodologies. I use industry-standard tools and frameworks such as Selenium and JUnit to write comprehensive automated tests that validate the functionality and performance of web applications. Additionally, I conduct thorough manual testing to ensure the highest quality and user experience. By employing agile development methodologies, I emphasize efficient collaboration, timely delivery, and continuous testing throughout the development lifecycle. My commitment to writing clean and maintainable code ensures easy maintenance and future enhancements. With a strong focus on user experience, I leverage React and Thymeleaf to create intuitive interfaces that captivate and engage users. With a track record of exceeding client expectations, I am dedicated to delivering high-quality software solutions that drive business growth and enhance customer satisfaction.
