Reverse Engineer | Windows Applications & Data Extraction (C++,C#,ASM)

Are you looking for a specialist to analyze, deconstruct, or modify a Windows application? Whether you need to extract hidden data from proprietary systems or inject custom logic into a compiled binary, I can help. I am a Reverse Engineer and Software Developer specializing in the Windows ecosystem. I dive deep into compiled code to understand how it works, fix compatibility issues, or extract critical business data from undocumented formats. 🛠 What I Can Do For Your Project: • Reverse Engineering & Analysis – Analyzing Windows applications (x86/x64), understanding internal logic, and identifying algorithms. • Data Extraction & Parsing – Dissecting and reverse engineering proprietary file formats and custom protocols to extract clean, structured data. • Application Modification – Code patching, custom DLL injection, and runtime application memory modification. • Custom Tool Development – Creating automation scripts, parsers, and custom software tailored to your specific technical task. Technical Stack: • Low-Level & Reverse Engineering: x86-64 Assembly (Assembler), Win32 API, DLL Injection, Memory Manipulation, Reverse Engineering Tools. • Programming Languages: C++, C#, Delphi. • Specialties: Binary analysis, proprietary file format parsing, memory hooking. ⚙️ Why Work With Me? • Deep Windows Internals Knowledge: I don't just use ready-made tools; I understand how the operating system handles processes, memory, and threads. • Clean & Secure Solutions: Any patch, injector, or parser I deliver is robust, well-documented, and fully functional. • Absolute Confidentiality: I respect NDAs and ensure that your proprietary project requirements and data remain secure. Let’s discuss your technical challenge. Click the "Message" or "Invite" button to share your project details, and I will provide an initial assessment of how we can solve it.
