    System Development & Reverse Engineering | C++, Assembly, WinAPI

    C & C++
    System Development & Reverse Engineering | C++, Assembly, WinAPI — example of freelancer's portfolio work in category C & C++
    I don't just write code — I manage hardware. I specialize in low-level development, where maximum performance and complete control over memory are required. If you need software that works "under the hood" of the system — you are in the right place.

    My competencies:

    … C/C++ & WinAPI: Creating system utilities, high-performance modules, and drivers.

    Assembly (x86/x64): Writing critical inserts for ultra-optimization, analyzing shellcodes.

    Reverse Engineering: Disassembling binary files, investigating software logic without source code (IDA Pro, x64dbg).

    Memory Work: Memory manipulation, DLL injections, API hooking, bypassing protective mechanisms.

    Game Scripting: Professional work with Roblox (Luau), developing complex ecosystems and cheat modules (Fabric/Mixins for Minecraft).

    I work quickly, rigorously, and for results. No junk in the code — only pure logic.

    System programming in C/C++ | Reverse engineering, Optimization

    C & C++
    System programming in C/C++ | Reverse engineering, Optimization — example of freelancer's portfolio work in category C & C++
    Are you looking for a developer who understands how hardware works, rather than just "gluing" ready-made libraries? I specialize in low-level development (C/C++), where every millisecond and every byte of memory is critical.

    I create software that operates at the system level: uncompromising speed, absence of unnecessary dependencies, and strict control over architecture.

    … What I offer:

    System programming: Development of utilities, high-performance modules, and software that interacts directly with the OS (WinAPI, working with threads).

    Reverse engineering and Modding: Analysis of binary files (IDA, x64dbg), working with process memory (Memory manipulation), creating DLL injections, API hooking.

    Game Hacking / Anti-Cheat Research: Development of custom modules for games, analysis of game logic, and bypassing protective mechanisms.

    Performance Boost: Total optimization of existing projects. I will rewrite your slow code from other languages (Python, C#, Java) to pure C++ for multiple speed increases.

    I do not create "business card websites." I solve complex technical problems where full control over the machine is required.
