About Me

Bio

Security Researcher with 4+ years of hands-on experience in embedded systems, reverse engineering, and malware analysis. As part of my research, I re-hosted satellite firmware, uncovered flaws in decompilers, and developed techniques to bypass ML-based security models. My work bridges low-level system internals with practical security applications, driven by a deep curiosity about system internals, vulnerabilities, and how to build more secure systems.
