Worked on the LizardByte/Sunshine repository to address a critical issue affecting touch input reliability on Linux platforms. Focused on stabilizing user input by ensuring that environment width and height values were always non-zero, this targeted C++ patch prevented input drops that previously impacted user experience. The solution involved precise debugging and minimal code changes within the linux/portal component, aligning the codebase with environment-dependent edge cases. Validation across multiple Linux environments confirmed improved input reliability and a reduction in user-reported issues. This work demonstrated strong skills in C++ programming and Linux development, with an emphasis on robust, maintainable fixes.
