Rockstar🎓
Top SchoolStefano Maggiolo is a Senior Staff Software Engineering Manager based in London with 17 years of experience blending rigorous mathematical training and competitive programming instincts into production software and ML-led products. At Google he has progressed from engineering roles across Maps, Offers and Android Location to leading the London Find Hub engineering org and applied-ML teams focused on 3DMA GNSS. He is comfortable across the stack—from front-end visualisations and data analysis to backend distributed systems—and still contributes to open-source tooling such as the Contest Management System used for IOI-like contests. A former IOI technical committee member and national trainer, Stefano pairs deep algorithmic intuition and academic discipline (PhD in Geometry) with pragmatic leadership that turns research-grade ideas into robust, scalable services. Notably, he has driven practical safeguards and scoring reliability in contest infrastructure, showing attention to correctness under adversarial inputs as well as production constraints.
