Mathew S.
FreelancerTop Rated Plus👋 Hi, I’m Matt - a senior C/C++ developer and reverse engineer with 15+ years of experience working across Windows internals, low-level systems, and complex software analysis.
My core expertise is understanding how software works under the hood. I specialise in reverse engineering applications, analysing Windows internals, debugging complex behaviour, and modifying or extending software at both user-mode and kernel level.
Over the years I’ve developed more than 500 desktop applications in C# and C++, built large-scale production systems used by millions of users, and led development teams delivering reliable, robust software for enterprise and financial organisations.
I operate comfortably at every layer of the stack - from kernel-mode drivers and memory analysis through to desktop applications, systems development, and backend platforms.
🔒 Windows Systems, C/C++ & Reverse Engineering
- Reverse engineering complex applications and software systems
- Understanding internal logic and reconstructing application behaviour
- Adding or modifying functionality in existing software
- Windows kernel driver development (WDM / KMDF)
- Static and dynamic analysis (IDA, Ghidra, x64dbg)
- Encryption / decryption analysis and algorithm reconstruction
- Anti-tampering and protection bypass analysis
- Driver debugging, crash dump analysis, BSOD investigation
- Syscalls, Windows exceptions, hooks and internal APIs
- Virtual / physical memory inspection and manipulation
- Assembly, pseudocode and binary analysis
- Researching undocumented Windows behaviour
- Performance optimisation at system level
If it runs on Windows, I can reverse engineer its logic, understand how it processes data, extract or reconstruct functionality, debug system-level issues, and alter behaviour where required - from user-mode applications down to kernel drivers.
🎮 Game Reverse Engineering, Cheats & Anti-Cheat Research
I have extensive experience reverse engineering games and building internal and external cheats, mods, and tooling.
- Internal and external game cheat development
- Reverse engineering game engines and client logic
- Working with major anti-cheat systems and protections
