A game developer with 10 years of hands-on experience specializing in reverse engineering, tooling, and pushing the technical limits of games. Notable open-source work includes backend development for the widely used UndertaleModTool, where they implemented support for new data structures, shaders, timelines, and editors while optimizing core decompilation and unpacking workflows. They excel at understanding internal file formats and translating that knowledge into practical modding features and bug fixes. Equally comfortable writing developer tools as crafting game systems, they bring a pragmatic, systems-level perspective to complex game internals. An inclination for low-level problem solving and tool-building makes them a strong asset for teams aiming to extend or modify existing game engines.
The most complete tool for modding, decompiling and unpacking Undertale (and other GameMaker games!)
