About Me

With over 5 years of programming experience, I shifted from ethical hacking and cybersecurity to software engineering at the beginning of 2025, realizing my main focus lies in building solutions rather than just securing them. Now, I'm focused on creating software that solves real-world problems, constantly refining my skills through hands-on projects and continuous learning.
