Basically this is a story about a guy who was smart enough to script up his trading tool (he discovered that there is an API and wrote some code to use it).
He trade other people's money, using other people's (probably employer's) account and resources, I suppose.
His employer have paid all the fees, and, took all the risks - if there is profit - it is mine, if there is a lose - it is theirs.)
The essence of trading is about having a special (insider) position of even being a market maker, who just collecting fees from every trade other people do.)
This is not even close to an accurate summary. He never stated that he had any employer backing, and he wasn't collecting market making fees. In fact he was paying brokerage fees which is the exact opposite.
An employee of what? He states above that he was paying roughly $200/month for a server and $1800/month for the software/data connections to his broker.
Basically this is a guy who does what many other have done, look no further than elitetrader.com, but smart enough to add "machine learning" to his story headline, which is the hottest buzz term on the street this year, everyone and his mom talks about machine learning last I checked.

But this is just my guess.
