She was preceded by Bankman-Fried's former close friend and college roommate Gary Wang, who was an FTX co-founder.
In response to questions from Assistant U.S. Attorney Nicolas Roos, Singh said he frequently went to Bankman-Fried to voice his concerns over the company's spending.
He told the court that he would tell Bankman-Fried he was "embarrassed" and "ashamed," and that the level of spending "reeked of excessiveness" and "flashiness."
Bankman-Fried faces seven criminal counts related to the collapse of FTX and Alameda, including wire fraud, securities fraud and money laundering that could put him in prison for life.
At the time, Singh pleaded guilty to six charges, including conspiracy to commit securities fraud, conspiracy to commit money laundering and conspiracy to violate campaign finance laws.
