Hope this is OK here (please say and will delete if not). We're two people looking for projects that focus on "maths". The idea is that most people here (most HN readers) can write code, but sometimes there is some part of a system that's a bit more mathematical and you want someone to help. For example, we're currently talking with someone about doing sentiment analysis.
Dude, there are soo many teams in Startup Chile that need technical consulting and have $$. Not all need "maths" whatever the hell that means, but I'm sure some are in your target. Are you in Santiago? We can meet up and chat and I can make some intros.
