Hello, Iām 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 Iām 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.
