About me
I am a beginner Java developer with one year of practical experience in developing small-scale projects using Java 17 and later versions. My tech
stack includes Spring, Hibernate, Junit + Mockito, React, and databases such as MySQL, PostgreSQL, and MongoDB. I hold a degree in Computer
Science, which has provided me with a solid theoretical foundation to complement my practical skills. In addition to my project work, I regularly
solve problems on LeetCode, which enhances my algorithmic thinking and problem-solving abilities. I am a stress-resistant, goal-oriented, and
punctual individual who takes deadlines and tasks seriously. I am sociable, open to feedback, and always eager to learn and adapt to new
challenges. I work well in a team environment, accepting criticism and advice constructively to improve both my skills and the outcomes of our
projects.
