What I'm looking for

I am looking for a role that fosters growth, innovation, and collaboration in cybersecurity.

I am a dedicated Cybersecurity Analyst with over a year of experience specializing in web security and incident response. My journey has been marked by a proven track record of securing over 1,800 malware-infected websites globally. I excel in threat detection, vulnerability assessment, and crafting tailored security solutions, always advocating for prevention through employee training and clear documentation.

In my role as a Web Security Analyst at Sectigo, I managed Tier 1 and Tier 2 teams, resolving critical incidents through advanced malware analysis and server inspections. I developed tools like the Joomla Analyzer, which significantly reduced manual workloads and optimized incident response times. My commitment to excellence has earned me recognition as a Top Performer of the Month multiple times, reflecting my dedication to client satisfaction and effective incident management.

My academic background in Computer Science Engineering, coupled with hands-on experience in developing innovative solutions like the Ransomware Early Detection System, has equipped me with the skills necessary to tackle complex cybersecurity challenges. I am always on the lookout for opportunities to enhance my knowledge and contribute to a secure digital environment.
