I am a self-motivated alumnus of the Computer Engineering and Informatics Department of Patras University, seeking a role in Software Engineering. Throughout my studies, I have gained hands-on experience with several programming languages including Java, Python, C/C++, MySQL, PHP, and HTML, and I thrive in collaborative environments focused on innovation and efficiency. Currently, I am fulfilling my military obligations as a Developer/Programmer for the Greek Army, where I manage and maintain army sites, further honing my skills in web development. During my university studies, I completed a master’s degree with a thesis focused on optimizing Dijkstra's shortest path algorithm using priority queues in C++. Additionally, I have completed internships and worked on web development projects involving modern web technologies. Continual learning is important to me, and I am actively advancing my skills through seminars on Java and Python programming. I am eager to contribute my technical expertise and problem-solving abilities to exciting software engineering roles.
