Worked on improving the stability and reliability of map rendering in the maplibre/maplibre-gl-js repository by addressing a critical bug related to overzoomed MLT tiles. Focused on ensuring that tiles with overzoom parameters consistently use MVT encoding, which resolved encoding mismatches that previously led to tile loading failures in edge cases. Enhanced the robustness of the tile loading process by introducing regression tests that lock in the correct encoding path and expanding test coverage for tile encoding logic. Utilized TypeScript for front end development and testing, contributing to more maintainable code and reducing the likelihood of future regressions in tile handling.
