I built a workflow engine with python and arangodb that I used to extract job listings from things like HN’s who’s hiring and America’s job bank and then evaluate if I want to apply, if I did apply, etc. The goal was to train a text classifier to filter job listings but I got a job with an A.I. company about as soon as I started using it by telling them about it.
After I left that place it took me a little longer to find my current job, if it had taken any longer I would have given myself a job cleaning out bogus job listings from the job bank (e.g. the Java job in Syracuse that is really COBOL and in Atlanta…)
I took the code out of mothballs and completed the classifier and now it is the smart RSS reader I knew was possible in 2005.
