Haniel Rolemberg
Problem Solver
Cancer has been part of my family for as long as I can remember — uncles, aunts, cousins, all fighting it at different points. At 16, my father was diagnosed with skin cancer. I didn't know then that survival depended so heavily on the type. To me, cancer meant one thing. That misunderstanding hit like a reset: a sudden urgency to live fully, to act, and to dedicate myself to problems that actually matter.
That urgency pushed me across fields — public policy, software engineering, data systems, cybersecurity, AI/ML. Not because I was chasing credentials, but because the hardest problems don't fit inside one discipline.
It also led me to build the Problem Solver Foundation — a community that connects people across borders to solve real-world problems using technology and science. My mission: impact one billion lives by 2035.
