We've been trying to find a second developer for the company and have posted job ads online but so far there have been no developers that have been interested, and only a single one that has some experience in Python (that failed a fairly basic practical).

It seems like the it's really difficult to find decent people here in Singapore, even reasonable juniors that you can teach. I'm contemplating whether I should go reach out directly to people on Stack Overflow and github and in the hopes that they are interested.

I'm thinking I would message the person with only a few sentences, stating the they seems capable from their online presence and that I'd like to work with them. Is this kosher? I know I dislike recruiters and unsolicited mail just as much as the next guy.
