$ whoami

I am a Cyber Security graduate and currently working as a Senior Network Automation Engineer at Hughes Systique Corporation (HSC). I hold a Bachelor's degree in Computer Science Engineering with a specialization in Cyber Security and Forensics from the University of Petroleum and Energy Studies (UPES), Dehradun, and have recently completed a PG Diploma in Automotive Security from BITS Pilani.

My expertise spans network automation, security automation, VAPT, cloud security, full-stack development, and penetration testing—a multidisciplinary skill set that allows me to bridge engineering with cybersecurity. I am passionate about building secure automation frameworks, developing tools that strengthen digital ecosystems, and enabling organizations to stay ahead of emerging threats.

I am also an active contributor to the security community, having presented at BlackHat MEA (2024) and BlackHat Sector (2024, 2025), where I showcased innovative tools and research. Looking ahead, I will be pursuing an MSc in Cyber Security Engineering at the University of Warwick, further deepening my academic and practical expertise in the field.
