Summary
👤
Senior🎓
Top SchoolChristophe-marie Duquesne is a Domain Technology Officer for Marketing at FlixBus with 16 years of experience applying data science, data engineering and software development to drive business decisions. A PhD in Computer Science and Applied Mathematics, he blends rigorous optimization expertise (airline fleet assignment solvers) with hands-on production engineering—having implemented real-time analytics pipelines (Snowplow, Kafka, Snowflake) that cut costs dramatically. He leads cross-functional teams (37 people across two locations) rearchitecting data platforms to embed GDPR-by-design while maximizing value extraction. An active contributor to open-source projects, he has improved tooling from LP solvers in PuLP to display and media handling in autorandr and Sigal, showing an unusual mix of systems, backend and optimization skills. Known for translating academic rigor into pragmatic engineering, he thrives at the intersection of research, reliability and product impact.
