Top SchoolAntonio Espinosa is an industry consultant and senior software engineer based in Barcelona with a decade of hands-on experience building secure, scalable web and back-office systems.

His background spans fintech, fraud detection, e-commerce and GIS platforms, where he has designed production-grade architectures, led integrations and delivered L2/L3 support for critical incidents.
