He came out of 9/11 unscathed — only to be killed when terrorists stormed an upscale hotel in Kenya’s capital this week.

Jason Spindler, a 40-year-old CEO of a technology consulting firm, was having lunch at the DusitD2 Hotel in Nairobi on Tuesday when al-Shabab militants — including a suicide bomber — attacked the complex with car bombs and gunfire, killing at least 21 people.

“Jason was a survivor of 9/11 and a fighter. I am sure he gave them hell,” his brother Jonathan Spindler wrote on Facebook.

The Houston native “was trying to make positive change in the Third World in emerging markets,” through the company he co-founded, I-DEV International, his mother, Sarah Spindler, told NBC News.

“We all miss him so much. And it’s so sad that such a bright young person is taken away by terrorism,” Spindler said.

Before dedicating himself to boosting Kenya’s local economy, Spindler worked on Wall Street.

It was while he toiled for now-defunct investment firm Salomon Smith Barney that Spindler escaped a first brush with death.

The firm was located at 7 World Trade Center, but Spindler was running late the morning of Sept. 11, 2001, and emerged from the subway as the first tower fell.

“Then he went back to help out and Building 7 fell and he was all covered in the dust,” his mother told KTRK-TV in Houston.

Friends and family said they were sure that Spindler jumped into action to help during the Nairobi attack as well. “When we hear explosions of gunfire, a lot of people immediately jump away. His instinct is quite the opposite — he jumps straight at it,” his college roommate, Kevin Yu, told the Washington Post.

After 9/11, Spindler’s life changed course. “Something struck a nerve and changed how he felt and thought about things,” Yu said. “He just felt like he could be doing so much more.”

He joined the Peace Corps and went to Peru to help farmers sell their wares to larger markets and benefit from the fruits of their labor. Later, he graduated from NYU Law School.

He had lived in Nairobi for the past three years, his mother said, adding that the family is traveling there to retrieve his body.
