Mathew S.

Hi, I’m Matt, a senior C/C++ developer and reverse engineer with 15+ years of experience specialising in Windows internals, low-level systems development, reverse engineering and complex debugging.

I help companies understand, fix, extend and build difficult Windows software. This includes C++ development, Windows applications, Windows internals, reverse engineering, kernel development, driver development, memory analysis and system-level debugging.

I have developed more than 500 desktop applications in C# and C++, built large-scale production systems used by millions of users, and worked with enterprise and financial organisations on technically demanding software.

My strongest area is solving problems that require a deep understanding of how Windows and software work internally.

C/C++ and Windows Development

• C and C++ development
• Windows application development
• Windows internals
• Windows API and system programming
• Windows kernel development
• Windows driver development
• WDM and KMDF
• User-mode and kernel-mode development
• Multithreading and concurrency
• Performance optimisation
• Memory management and analysis
• Crash dump and BSOD investigation
• Debugging complex Windows software
• Legacy C/C++ code analysis and refactoring

Reverse Engineering and Binary Analysis

I specialise in reverse engineering software where the source code, documentation or internal behaviour is unavailable or not fully understood.

I can help with:

• Reverse engineering Windows applications
• Static and dynamic analysis
• IDA Pro
• Ghidra
• x64dbg
• Assembly and pseudocode analysis
• x86 and x64 software analysis
• Memory analysis
• Runtime behaviour analysis
• Reconstructing algorithms and application logic
• Analysing proprietary protocols and data formats
• Encryption and decryption analysis
• Software protection and anti-tamper research
• Modifying and extending existing software

Whether you need to understand a Windows executable, investigate how a system works internally, reproduce behaviour, diagnose a difficult issue or extend an existing application, I’m comfortable working at both user-mode and kernel-mode level.
