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.
Taking a Machine Learning and Statistics course does not make you a trader. You need something else - access to the system.
This is why my guess is that he was an employee.
