Summary
👤
Senior🎓
Top SchoolAntoine Legrain is a professor and applied mathematics researcher with 11 years of experience building optimization software for transportation, healthcare, and logistics systems. He holds a Ph.D. from École Polytechnique de Montréal and has translated theory into production-grade backends—from on-demand campus shuttles at the University of Michigan to banknote distribution and homecare nurse scheduling. Skilled in C++, Java, Python, NodeJS and mathematical modeling, he blends algorithmic rigor (online and stochastic optimization) with practical engineering to deploy real-world systems. His work uniquely bridges academic research and industry impact, including collaborations with cancer centers and central banks that shaped operational decisions. Based in Montreal, he is equally comfortable designing models on paper and shipping the software that runs them.
