Proficient in C/C++ for systems-level programming.

In-depth understanding of Windows internals (e.g., kernel-mode drivers, memory management, system calls, PE file format).
Experience with kernel-mode debugging and root cause analysis.
Familiarity with secure coding practices and low-level exploit mitigation techniques (e.g., PatchGuard, CFG, DEP/ASLR).
