Summary
👤
Senior🎓
Top SchoolMarek Narozniak is a founder and CEO with a decade of engineering and research experience spanning Poland, France, China, and New York, holding a PhD in Physics from NYU and a master’s in Optimization. He blends deep technical rigor—demonstrated by research on quantum adiabatic mapping and contributions to the widely-used QuTiP quantum toolbox—with hands-on product and engineering leadership in startups he founded, including sqrtxx.com and singleton.id. His background ranges from low-level backend and QA work (adding robust RNG seeding and solver improvements to QuTiP) to building embedded survey systems on Raspberry Pi and production web services. Comfortable moving between research and shipping products, he has a knack for turning complex optimization and quantum ideas into practical implementations and reliable testable code. Based in Warsaw, Marek combines academic depth with entrepreneurial drive and a proven ability to operate across international tech ecosystems.
