DATA SERVINGTHE BUSINESS.
I work where architecture meets outcomes. Connecting complex systems, making data reliable, and keeping every technical decision tied to business value.
From strategic accounts at Criteo to healthcare integrations at Doctolib, payment experiences at Alma and real-time data pipelines at RudderStack — four environments, one method: understand the business, design the system, deliver the outcome.
