A vengeful ex-boyfriend who works for billionaire George Soros stalked his former gal pal under the online moniker OrgyMan, then trashed her finance career when she refused to reconcile, she claims in a $250,000 Manhattan lawsuit.

Polish knockout Marta Billeci earned $110,000 a year as a saleswoman for software company CQG until she broke up with Soros Fund Management administrator Taye Famm, 38, who barraged her with 99 texts and e-mails after the breakup, according to state Supreme Court papers.

“Despite the repeated messages and e-mails from [Famm], [Billeci] made it clear that she no longer wanted to have anything to do with him, as she learned from various other sources that [Famm] had a history of stalking and instilling fear in other women he dated,” her suit says.

Mr. Wrong also set up an account on the singles Web Site Match.com under the name OrgyMan to harass her, she claims in the suit.

“About February 2012, [Famm] threatened [Billeci] by telling her that he would destroy her career in the financial-services industry and have her prosecuted criminally if she refused to meet with him,” the filing said.

When she nixed Famm’s offer to kiss and make up, the Jersey City man filed a Family Court petition last May based on “outright lies” to get an order of protection against Billeci, 40, she says. He then allegedly left her messages and, when she returned calls, filed a complaint that she had violated the order.

Billeci was arrested June 8, 2013, according to criminal records, and charged with a misdemeanor for disobeying a court order that barred her from contacting Famm. She was released without bail and her case will likely be dismissed by her next court date in October, records show.

The blond beauty lost her job and has been unable to find work.

In court papers, the Baruch College grad claims Famm sent her insider information on publicly traded companies gleaned from his work at Soros’ company.

Famm declined to comment. A Soros Fund spokesman said Famm is a back-office administrator with no role in the investment side of the business. A call from The Post was the first the spokesman had heard of the insider-trading allegations. He said he is looking into the matter.
