👨‍💻 Quantum

.NET developer specializing in system programming and application security.
Deeply involved in Windows Internals, Reverse Engineering, code obfuscation, and .NET protection (JIT & Native AOT).

I build complex protection systems for .NET applications by combining knowledge across all levels — from hardware to the CLR.

➤ Proficient in a wide range of modern protection techniques:
• Anti-Debug | Anti-Injection | Anti-Dump | Anti-Virtualization | Anti-Sandbox
• Hook Detection
• Anti-DLL Injection & DLL Verifier
• Code Integrity Checks (Static and Runtime)
• Memory Integrity Checks
• Assembly Load Monitoring
• Detection of abnormal behavior & tampering attempts
• Reverse Engineering mitigation & hardening
• Other various checks

➤ Specialization in Native AOT protection:
• PE section integrity validation
• Import/Export table verification
• Code replacement prevention & foreign section injection protection
• Low-level hooks to prevent bypassing protections
• Memory access monitoring of critical regions
• Other Checks

➤ Post-build MSBuild customization experience:
• Automated integration of protection layers after compilation
• Enhanced build-time security for C# projects

• Low-level Windows development: Working with processes, threads, and memory via WinAPI and direct syscalls. In-depth understanding of Windows internal structures like PEB and LDR.
• IL code analysis and modification: Skilled in using dnlib and Mono.Cecil for inspecting, obfuscating, and protecting .NET assemblies.
• Unsafe code & memory manipulation: Confident use of pointers and low-level memory operations to maximize performance and implement custom protection mechanisms.

• Languages: C# (including unsafe code, P/Invoke, Low-level)
• Platforms: .NET Framework, .NET Core / .NET 5+
• UI: WinForms, WPF, ImGui
• Databases: MySQL
• Analysis Libraries: dnlib, Mono.Cecil
• Additional: Backend development experience (API design, database communication)
