IndiaWhat I'm looking for
I am a Senior Security Engineer with over six years of corporate experience and more than a decade in cybersecurity, focused on web, mobile, and 0-day vulnerability research.
I have discovered and reported Android 0-day vulnerabilities to Google and exposed a smart-grid security flaw that risked state-wide electricity controls; I have presented on these findings at international venues such as Nullcon.
In corporate roles I have built in-house security automation tools, led Secure-SDLC initiatives, performed SAST/DAST and code reviews, and managed developer teams to align security tasks across releases.
I also teach and created a Kickstarter-launched Ethical Hacking course on Udemy with 300+ students and a 4.4 rating, and maintain personal security projects including Vajra and Trishul.
