PROFILE

Frans Skarman

Worked on helix-editor/helix and typst/typst, delivering targeted language tooling and export enhancements. Developed Spade language support for Helix, integrating language server protocol, grammar parsing, and syntax highlighting using Rust and Tree-sitter to enable robust language-specific features. Upgraded Spade grammar to improve highlighting accuracy for advanced directives and maintained alignment with upstream changes for easier future updates. In typst/typst, enhanced the HTML export pipeline by implementing phrasing content grouping and refining semantic structure, resulting in cleaner, more accessible HTML output. Collaborated cross-functionally and focused on maintainability, export quality, and developer ergonomics throughout each project phase.
