TuxSH
Software Engineer
Summary
🤩
RockstarSoftware Engineer with a decade of hands-on experience in low-level systems, firmware and homebrew for Nintendo platforms. Known as a lead developer on Luma3DS and an author of 3DS exploits, they contribute to high-profile open-source projects like Atmosphère and libnx where their work spans TLB/cache management, SVC implementations, socket wrappers and cross-platform porting. Their strengths lie in reverse engineering, memory and interrupt management, and pragmatic refactoring that improves maintainability across large C codebases. Comfortable operating close to hardware, they routinely touch assembler and system headers to get services and networking working reliably. An underappreciated asset: they blend exploit development intuition with production-grade engineering practices to deliver robust custom firmware and homebrew infrastructure.
