Worked on the PepperDash/Essentials repository to address a reliability issue in file search functionality, focusing on back end development using C#. Delivered a targeted bug fix by implementing case-insensitive filtering for file names and extensions, ensuring that users can retrieve relevant files such as zip and JSON regardless of input case. The solution involved normalizing file names within the search logic to align results with user expectations across platforms. This change improved the robustness and consistency of file retrieval, reducing missed results and enhancing the overall user experience. The work demonstrated attention to detail in search logic and C# implementation.
