Worked on the maplibre/maplibre-tile-spec and CommanderStorm/martin repositories, delivering six features and two bug fixes over two months. Focused on enhancing the encoding pipeline, improving documentation clarity, and ensuring cross-platform build reliability, particularly for WebAssembly. Addressed geometry handling for polygons and multi-polygons, integrated tessellation, and optimized tile encoding with lightweight compression. Improved deployment compatibility by expanding relative URLs and standardized test outputs to reduce flakiness. Fixed encoding mismatches between TypeScript and Rust, ensuring consistent data processing. Used Rust, TypeScript, and backend development skills to strengthen code quality, streamline data encoding and decoding, and support cross-language verification and documentation.
