Cesare Soldini is a Director of Technology based in Milan with 11 years of hands-on experience building full‑stack web applications and leading engineering teams. He progressed from junior dev and system admin roles into senior and leadership positions at Accurat, specializing in interactive, browser‑based data visualizations using modern front-end stacks (ES6, React, MobX) while retaining strong backend chops across Ruby, Python and PHP. An active open‑source contributor, he improved validation and developer ergonomics in the widely used mobx-state-tree library, surfacing clearer error messages and adding robust tests. A self‑taught programmer and former particle physics student, Cesare pairs analytical rigor with practical engineering, and his off‑hours pursuits—3D printing, climbing, freediving and bike mechanics—reflect a hands‑on problem‑solving mindset that informs his approach to product and platform challenges.
