What Do I Do

Professionally, I work as a Penetration Tester Team Leader on a Cybersecurity Consultant company in Indonesia. I began my career as a Software Developer. While honing my coding skills, I developed a keen interest in security, analyzing systems from both a black-box and white-box perspective. This curiosity led me to delve deeper into cybersecurity, ultimately prompting a career shift in 2022.

Throughout my career, I have excelled in many penetration testing engagements. I am passionate about identifying vulnerabilities that could compromise systems and data. One of my notable achievements was successfully leading a team in a penetration testing that uncovered critical vulnerabilities in a major client's network, as well as fraudulent transaction by abusing their business logic flaw in my client's web app, resulting in significant security improvements. Not only that, I also achieved several certifications, such as:

  1. Certified Ethical Hacker (CEH) - Practical (Jan 2022)
  2. eLearnSecurity Web Application Penetration Tester (eWPTv1) (Jun 2022)
  3. eLearnSecurity Junior Penetration Tester V2 (eJPTv2) (Aug 2022)
  4. eLearnSecurity Web Application Penetration Tester eXtreme (eWPTXv2) (Oct 2022)
  5. OffSec Certified Professional (OSCP) (Aug 2023)
  6. CREST Practitioner Security Analyst (CPSA) (Sep 2024)
  7. CREST Registered Penetration Tester (CRT) (Sep 2024)
  8. OffSec Web Expert (OSWE) (On Progress Lab)

Me and Hobbies

Aside from tinkering Cybersecurity stuffs and hunting some bugs on bug bounty platform on my spare time, I consistently hit the gym 3-4 times a week, following a basic Push-Pull-Leg split. I’m also passionate about combat sports—I’d call myself a martial arts enthusiast, mainly experienced in Taekwondo, Muay Thai, and Boxing. While I'm well-versed in striking and stand-up fighting, I plan to explore another martial arts that focus more on ground or grapple-based fighting such as BJJ or Judo. Additionally, I'm interested in any kind of tactical self-defense such as Libre, Arnis, Krav Maga, and Silat to expand my fighting arsenal further.

Speaking about myself, i'll let the Grok analysis explains further about the personality of mine:
