About Oleksandr Kleus

As a highly skilled and experienced full-stack developer with a background in system administration, I possess a strong understanding of both the server and client-side of web development. My primary programming language is PHP, and I have worked with versions 5.3-7.4, as well as various frameworks such as Laravel, Symfony, and Yii2. I am also proficient in databases including MySQL, PostgreSQL, and Oracle. With experience working in Windows and Unix/Linux environments, I am comfortable utilizing REST and SOAP-based system interfaces. I have strong skills in leadership, communication, and project management methodologies such as Scrum. In addition to my technical skills, I am also proficient in NodeJs, Python, and Git, among others. With my extensive knowledge and experience, I am confident in my ability to excel in any software engineering role.
