About Me

Strategy Meets Execution

I bridge the gap between vision and delivery in complex, global environments

Strategic Product Owner with deep expertise in digital transformation, platform modernization, and cross-functional leadership within highly regulated and agile environments (SAFe, BizDevSecOps).

I thrive in distributed, multicultural teams and excel at translating complex business needs into scalable, intuitive, and secure digital products. Passionate about improving user experiences, reducing friction, and driving adoption across large ecosystems.
