Worked on the DaVikingCode/RTKLIB repository to enhance RTKPlot’s usability and reliability, focusing on high-DPI display support and robust drag-and-drop file handling. Implemented a scaled drawing buffer using devicePixelRatio in C++ and Qt, improving map image rendering for high-resolution screens. Addressed a file path extraction issue by refining the drag-and-drop workflow, ensuring that map, sky, and solution files are correctly identified and processed by the application’s data readers. These updates streamlined the user experience, reduced data ingestion errors, and enabled smoother data inspection workflows, demonstrating strong skills in GUI development, file handling, and cross-platform interface adaptation.
