As a driven fourth-year Software Engineering student at Bahçeşehir University, I have developed a deep passion for cloud computing, artificial intelligence, and data science. My academic journey is complemented by hands-on experience, both in Turkey and as an exchange IT student at Bay Atlantic University in Washington, DC. This international exposure has broadened my industry perspective, allowing me to build a diverse network and gain invaluable insights. During my studies, I have actively engaged in rigorous coursework and projects that have sharpened my coding skills and understanding of best practices. My practical experience includes working with advanced technologies like Docker and Kubernetes, as well as contributing to innovative data science initiatives. A six-month internship at Panasonic as a business analyst further enriched my understanding of large-scale project execution and real-world project management. I thrive in collaborative environments, where my ability to work effectively within a team has been a key asset. I am particularly drawn to the dynamic and ever-evolving fields of IT, data science, and cloud technologies, where teamwork and continuous learning are essential. Beyond technical skills, I am passionate about project management and have taken the lead in organizing workshops, hackathons, and summits. These experiences have not only honed my project management abilities but also allowed me to contribute to significant technological advancements. I am committed to staying at the cutting edge of technology, believing that success in this field requires a blend of technical expertise, adaptability, and strong communication skills. With a solid foundation in both theory and practice, I am eager to make meaningful contributions to the tech industry and continue growing in my career.
