Summary
👤
Senior🎓
Top SchoolMathias Fonseca is a Solutions Architect with 12 years’ experience designing and scaling payment and fintech systems across Latin America and Europe, currently building ledger-based payment infrastructure at Payrails in Berlin. He previously led global payments and fraud prevention efforts at Delivery Hero and PedidosYa, where he combined hands-on full-stack engineering with cross-market architectural leadership. Comfortable switching between deep technical design and stakeholder-facing consulting, he’s known for keeping large, distributed projects consistent and performant across many countries and payment methods. An experienced educator and former university professor, he brings clarity to complex architecture topics and has mentored engineers while teaching software architecture and cloud subjects. He also has startup CTO experience in AI-driven transportation, reflecting a breadth that spans payments, big data and machine learning. Unusually for a Uruguayan, he’s not into football—an offbeat detail that underscores his tendency to follow less conventional paths.
