On my wishlist are some fuzzier categories:
1. Tech trends (rust, docker, postgres...)
2. Role trends ("ml engineer", "full-stack developer" ...)For the additional filters, by technologies and role types it would be of great help if I could find some high level indexing and fuzzy search tools/libraries. I would probably need to migrate from SQLite to Postgres and when I am already there probably use ORM too.
Certainly, I would need to do serious research, if there is enough public interest in the current website and I manage to find some contributors with data science and information retrieval experience maybe we can add many interesting filters like tech, roles, location, visas, remote, etc.
