Worked on the solidjs/solid-start repository to migrate code syntax highlighting from Shikiji to Shiki, focusing on updating imports and API usage throughout the codebase. This transition leveraged TypeScript and modern dependency management practices to improve code block rendering and expand language support for contributors. The migration preserved existing behavior while aligning the toolchain with current dependencies, reducing maintenance debt and streamlining future upgrades. No major bugs were addressed during this period, with efforts concentrated on delivering this key feature. The work demonstrated skills in frontend development, code highlighting, and library migration, resulting in a more maintainable and contributor-friendly codebase.
