"I break into systems ethically, uncover security flaws, and build resilient software architecture."


I am a Security Researcher Operator Classified // Lvl 21 based in Rajasthan, India. My focus centers on ethical hacking, web penetration testing, network reconnaissance, and low-level software engineering — approaching security assessments beyond automated scanning scripts.


Currently working as a Backend AI Engineer Intern at Flyrank AI, I architect high-throughput backend endpoints, implement strict API security boundaries, and explore the intersection of distributed systems and autonomous AI agent workflows. I also hold the Cisco Certified Ethical Hacker certification with practical experience in Linux system internals and network protocols.


From architecting vulnerable cybersecurity training platforms (Hyperion) and high-concurrency network discovery tools (ReconX) to automated DAST vulnerability pipelines (BlackHawk), I engineer offensive security tooling and resilient software architectures that test and fortify modern attack surfaces.
