ABOUT ME

I am an aspiring Cybersecurity Researcher, VAPT Analyst, and SOC Analyst with hands-on experience in penetration testing, vulnerability assessments, and real-time threat monitoring. I focus on identifying and mitigating security weaknesses through practical exploitation and SIEM‑driven defense strategies.

Currently I am pursuing cybersecurity at Offenso Hackers Academy, where I perform security assessments, participate in CTFs, and design lab scenarios around NIDS, FIM, and automated SSH brute‑force detection using platforms like Wazuh and Splunk.

I completed my BCA at Kannur University, where I built “DAYCARE”, a real‑world application created to streamline childcare management across mobile and web platforms, reinforcing my full‑stack and problem‑solving skills.

I am deeply passionate about ethical hacking, security research, and continuous learning. I enjoy collaborating with teams, breaking down complex security challenges, and contributing to building a safer digital world.
