Rio D. (riodrwn)

Hi, I'm Rio an offensive security engineer and security researcher based in Indonesia. I specialize in penetration testing, red teaming, and vulnerability research across web applications, mobile applications, APIs, Active Directory, and enterprise infrastructure. Throughout my career, I've helped government agencies and private organizations identify and remediate security weaknesses before they become real threats. Outside of client engagements, I actively participate in bug bounty programs, publish CVEs, build security tools, and enjoy solving CTF challenges. I'm passionate about continuous learning, sharing knowledge, and pushing my offensive security skills further every day.
