PROFILE

Joshua T. Fisher

Worked on cross-platform build systems, audio subsystem development, and CI/CD automation across projects such as shadps4-emu/ext-SDL and ran-j/PS2Recomp. Enhanced CMake-based build workflows to improve IDE integration, documentation clarity, and build reliability, using C, C++, and YAML for configuration and scripting. Delivered an SDL3 audio subsystem port for libsdl-org/SDL, introducing improved device management and recording support. Optimized code generation in PS2Recomp by refactoring data structures for O(1) symbol lookups and modularizing build components. Focused on maintainability, performance, and developer experience, with targeted improvements to automation, testing, and cross-platform compatibility throughout the four-month period.
