Summary

Senior🎓
Top SchoolSylvain Viollon is a senior DevOps engineer and former CTO with nearly two decades of experience designing, modernizing and operating secure, high-performance SaaS platforms, particularly in the demanding healthcare domain. He combines hands-on Python and TypeScript development with infrastructure expertise—ranging from FreeBSD and Linux hosting to cloud-native DevOps practices—to deliver reliable, compliant systems at scale. As CTO he led cross-functional teams, overhauled legacy architectures, and introduced migration paths (including server-driven UIs and DSLs) that cut operational overhead and sped development. His background in deep integrations (HL7/FHIR, LDAP, Kerberos, CMIS) and large deployments informs a pragmatic approach to privacy, security and interoperability. Based in Rotterdam, he now focuses on bridging engineering strategy and execution to turn complex regulatory constraints into maintainable, auditable solutions.
