I am a senior cyber security specialist who is passionate about information security, especially in the area of web and network penetration testing. I obtained OSCP, OSWP, OSWE and OSEP certificates within one year and I also held a standing record on Hack-the-Box and identified more than 5 Common Vulnerabilities and Exposures (CVE).I'm truly passionate about my work and always eager to connect with other pentesters. While I enjoy all aspects of my job, I think my favorite part of my job is identifiying unknown vulnerabilities and writing a profession report for our clients.
