Senior🎓
Top SchoolSylvain Zyssman is a Head of Engineering and fractional CTO with 20+ years of hands-on software and leadership experience, specializing in rescuing high-risk AI, data and platform projects. He combines technical audits, ISO 27001 lead-auditor rigor and DORA-informed risk management to secure architecture, governance and compliance in sensitive contexts such as legal tech and clinical trials. Sylvain has led end-to-end deliveries from building datalakes and LLM-based search engines for large training networks to designing sovereign Azure architectures for document-processing chatbots. Comfortable switching between short, intense on-site missions and remote advisory work, he focuses on clear decisions, responsibilities and minimal meeting overhead to restore delivery momentum. Former co-founder and CTO with deep experience in cloud-native CI/CD, Pulumi/Kubernetes and scalable data pipelines, he balances strategic steering with occasional hands-on development to keep technical skills current. Based in Caen, France, he uniquely pairs practical experimentation with formal audit discipline to revive troubled projects and align them with regulatory and business constraints.
