Computer Engineering Student & Software Developer
About Me
I'm a Computer Engineering student at RWTH Aachen University with a solid foundation in both theory and hands on experience, and a strong passion for software development. I'm particularly interested in machine learning and data, and how they can be used to build intelligent, impactful systems. I'm always working on something, whether it's for a course or just out of curiosity. I love solving real problems, exploring new technologies, and turning ideas into useful, working software.
