Summary
🤩
RockstarMark Ludwig is a software reverse engineer and game-focused developer with 12+ years of experience specializing in x86 assembly, C/C++, C#, Lua, and Python. Based in California, he builds tooling to parse and edit proprietary game file formats and reverse-engineer game logic, often shipping concise console utilities and experimental WinForms/WPF GUIs. His open-source work includes contributing AI refactors to the Driver 2 PlayStation reverse-engineering project and enhancing ScriptHookVDotNet to expose vehicle properties for GTA V scripting. Practical, detail-oriented, and comfortable navigating low-level machine code, he pairs hands-on reverse engineering with disciplined Git-based project management. An unexpected strength: he frequently turns brittle reverse-engineering breakthroughs into maintainable interfaces that other developers can reuse.
