About Me

After graduating from Ondokuz Mayıs University with a 4.0 GPA as the top student in the Computer Programming Department, I completed my bachelor’s degree in Mathematics and Computer Science at Eskişehir Osmangazi University, once again as the valedictorian of my department. At the same time, I successfully completed my Bachelor’s degree in Economics at Anadolu University along with a Pedagogical Formation Certificate. During my graduate studies, I focused on Artificial Intelligence within Computer Science, further deepening my academic expertise.

My journey in mobile software development began in the early 2010s, which over time enabled me to specialize in the Android ecosystem. Today, I possess extensive knowledge of Java, Kotlin, Jetpack Compose, MVVM, and Modular Architecture. As an experienced Android Developer, I strictly adhere to clean code principles and focus on building scalable, sustainable, and user-centric solutions.

Throughout my career, I have contributed to high-impact projects such as YaaniMail (Mailim), İstanbulkart, Mobiett, Turkcell Digital Operator / Pasaj, and Tuttur.com, many of which reached millions of users. In most of these projects, I took on team leadership roles, where I not only provided technical direction but also ensured team efficiency, collaboration, and alignment with project goals.

On the academic side, I served as a lecturer at Medipol University, where I taught courses such as Android, Kotlin, and Python Programming. This role gave me the opportunity to share my industry knowledge with students and contribute to the development of the next generation of software developers.

In addition to my professional and academic background, I hold several patents, have authored published books, and contributed to academic research. I strongly believe that my skills in teamwork, problem-solving, and leadership enable me to deliver innovative, reliable, and long-lasting solutions in every project I take part in.
