I am doing media monitoring, I collect vast amounts of data on social networks, p2p, rss, webscraping ... then built reporting tools on top of it - high level trend reporting, customer segmentation for acquisition and brand targeting, planogram computing based on collaborative filtering, an entire media and brand intelligence platform.

I also do Forex trading with TensorFlow, but that's only making about 70-80k a year, which is probably a living wage, but not if you're in London and have an insatiable appetite for GPU's like me ;)
