I created Jobpig as a Pandora-like (thumb up/down) to filter jobs based on preferences, increasingly personalized over usage. It works more like Pandora than other learning boards; where jobs match users via hard-coded features (a la Music Genome Project) rather than collaborative filtering. These features include: location, commitment (eg full-time), company, source (eg stackoverflow), skills (eg python), and remote.
Eg I personally seek React, Python, Postgres, Remote, Part-time, Contract. That's combo's a tough ask on most boards; but Jobpig finds the closest match to my criteria, and it's working quite well for me. It scrapes these boards[1] (discuss[2]), and employers can post custom jobs. It's open source[3]. Any feedback would be greatly appreciated!
