Tristan N.

I am a technical Penetration Tester and Reverse Engineer with a deep focus on binary analysis and application security. I specialize in dissecting compiled applications to understand their internal logic, modify features, and uncover security vulnerabilities. Core Competencies: Windows Reverse Engineering Binary Modification: Expert in analyzing C/C++ and C# (.NET) applications. Structure Knowledge: Deep understanding of the PE (Portable Executable) file format and Windows internal structures. De-obfuscation: Capable of handling and bypassing basic binary obfuscation and packing techniques to restore code readability. Android/Mobile Security APK Analysis: Proficient in decompiling and analyzing Android applications (Java/Kotlin) to extract hidden API endpoints and logic. Native Library Analysis: Experience working with JNI and Native code (.so files) within APKs, not just the Java layer. Dynamic Testing: Debugging/Using instrumentation to hook functions and manipulate execution flow. Technical Toolkit: Debuggers & Disassemblers: IDA Pro, x64dbg, DnSpy, JADX. Analysis Tools: PE-bear, Detect It Easy (DIE), Frida, Burp Suite. Programming: Python, C/C++, C#, Java. Whether you need a legacy application patched, an API structure uncovered from a mobile app, or a security assessment of your compiled software, I bring the precise, low-level skills required to get the job done.
