The person behind the work
My story.
I’m a tech entrepreneur and nuclear engineer. I turn complex technical problems into products, ventures and tools people can use.
Today, I’m building at the intersection of nuclear engineering and AI. My projects include Reactor Atlas, which makes the world’s nuclear fleet explorable, and Criticality, where reactor physics becomes interactive simulation. I’m interested in making deep technical knowledge useful beyond the people who already understand it.
I co-founded Rather Labs, an engineering company we grew to more than 130 people. Alongside ventures like TranscribeGo, it taught me how to take an idea through product development, build the team around it, and deliver technology used by millions.
My foundation is nuclear engineering at Instituto Balseiro, where I also completed a master’s in engineering. At CNEA, I worked on simulation and safety analysis for the RA-10 research reactor. Later, I brought that computational experience into software and financial infrastructure, including technical leadership at Membrane.
Across these ventures, I work from first principles: understand the problem, build something useful, and create the organization that can carry it forward. That’s the thread connecting my work in nuclear technology, AI and entrepreneurship.
