Worked on enhancing the Vulkan rendering path in the defold/defold repository, focusing on stability and hardware compatibility. Addressed a critical issue by implementing a guard that checks for the presence of the VK_EXT_fragment_shader_interlock extension before initializing related fragment shader features. This defensive programming approach in C++ and Vulkan prevents crashes and undefined behavior on GPUs lacking the extension, improving reliability across diverse hardware. The work demonstrated strong skills in graphics programming and low-level development, reducing production risk and supporting safer onboarding for new hardware configurations, particularly in enterprise environments where broad GPU support and stability are essential.
