Have a REMOTE opportunity that hasn't gotten all the way to "desired salary range" but is exploratory, as-in I need help to get something done faster and if I find someone that can help quickly, and accurately, I would pay them... See https://kotlinlang.slack.com/archives/C0CMKCL87/p1564154983005300 and ask me questions in DM and we can explore this together. Outside of PSI, other experience with language AST, language transformation, and the libraries out there for parsing and working with Python, JavaScript, TypeScript, are valuable as well. The innards of language servers another plus.
