Summary
👤
Senior🎓
Top SchoolGuillaume Kergreis is an Investment Banking IT Auditor with a decade of hands-on experience at Société Générale, combining computer science engineering with a master’s in innovation management to bridge technical delivery and audit-driven risk control. He has built data-driven audit tooling and Python libraries, led POCs and deployment projects across Paris, London and Bangalore, and served as a data scientist on audit missions to translate messy data into actionable risk findings. His earlier work as a Scala backend engineer on SEPA payment modules and open banking APIs gives him deep payments and core-banking technical knowledge alongside practical experience with Kafka, Cassandra and functional Scala stacks. Comfortable in international, multidisciplinary teams, he repeatedly improves processes through automation, knowledge management and pragmatic tooling. Not obviously, he pairs enterprise audit rigor with startup-style engineering: shipping production-grade features and prototypes while keeping an auditor’s eye for control and compliance. Based in Nanterre, he is focused on leveraging emerging tech to modernize financial controls and inspection workflows.
