Worked on the bluesky/tiled repository to deliver subsampling-enabled PNG rendering in the web frontend, enabling efficient visualization of large 2D arrays. Utilized React for front end development and implemented the feature using JavaScript and TypeScript, focusing on improving responsiveness and reducing bandwidth for high-resolution images. Addressed the PNG request flow to ensure correct image construction and retrieval for subsampled 2D arrays, and expanded automated test coverage for both standard and strided array rendering in the ArrayND component. Updated project documentation to reflect these changes, supporting scalable data exploration and enhancing the reliability and performance of large dataset visualizations.
