About Me

As a passionate Cyber Security Engineer from Salem, Tamil Nadu, I navigate the digital landscape with both vigilance and curiosity. My journey in cybersecurity stems from a fundamental belief that robust security is the backbone of our increasingly connected world. My academic foundation in Cyber Security Engineering from Paavai Engineering College, combined with specialized training at NIIT Chennai, has equipped me with both theoretical knowledge and practical skills. I view cybersecurity not as a series of technical puzzles, but as a critical business function that enables organizational confidence. My approach balances technical expertise with a genuine commitment to protecting digital infrastructure in an increasingly vulnerable environment.

I thrive in Penetration testing, Vulnerability assessment, and Network security, approaching each challenge with methodical precision. My proficiency extends across multiple Linux environments, where I've developed keen understanding of system administration and security hardening. Through programming skills in Python, Java, C, and C++, I bridge the gap between security theory and practical implementation. I've built expertise with industry-standard tools including Wireshark, Metasploit, Burp Suite, and OWASP ZAP to identify vulnerabilities. My technical foundation allows me to adapt to emerging threats while maintaining strong fundamentals in core security principles.

My project portfolio demonstrates a hands-on approach, from developing Sentinel-Site for forensics to creating ML models for malware detection. I believe true security expertise comes not just from identifying vulnerabilities, but from engineering practical, effective countermeasures. When approaching security challenges, I combine technical acumen with meticulous attention to detail, leaving no vulnerability unexplored. My fascination with cyber forensics drives me to understand not just prevention, but also investigation and evidence gathering. Each security solution I develop aims to address real-world challenges while maintaining the delicate balance between protection and usability.

My professional journey is marked by continuous learning, reflected in my pursuit of industry certifications including CEH and RHCSA. I am particularly drawn to threat intelligence and SOC operations, where human analysis and technological tools create comprehensive defense. Throughout my career development, I've cultivated both technical skills and the ability to communicate complex concepts to diverse stakeholders. I approach team collaboration with enthusiasm, recognizing that effective security emerges from diverse perspectives and collective expertise. I am energized by the opportunity to contribute to organizations where I can protect critical assets while continuing to grow as a security professional.
