Looking for a Lezer/CM guru for a few hours (?)

I have a working CodeMirror for a small project, including a custom Lezer grammar that is barely passable. It’s a simple DSL, but I need an experienced Lezer/CM developer to:

  • Refine the grammar to properly highlight
  • Get a folding gutter working for an indent-based DSL (no delimiters)

PM message me if you can help. Thank you!
