Hello, I’m Galih Anggoro Prasetya, I live in Tegal, Indonesia. I focus on backend development and penetration testing, with a particular interest in red team offensive security, as I’m passionate about the security aspects beyond just writing code. My primary backend technology is Laravel. For penetration testing activities, I utilize various automated and manual tools to accelerate the process of vulnerability detection and exploitation.
I believe that a strong system is not built solely with good code, but also with a deep understanding of its potential vulnerabilities. Therefore, I continuously develop my skills in backend development and web application security to create solutions that are secure, efficient, and scalable.
