I did about 6 months as a part time TA for a virtual coding bootcamp a while back to earn a little extra cash. The pay wasn't great, but it was easy work and not too many hours. Might be ideal for someone in your situation.

Means testing is when the government uses your income to determine eligibility for a benefit. It's why you have to worry about making "too much" money to continue qualifying for disability assistance.
