Helsinki, Finland
Summary
🤩
Rockstar🎓
Top SchoolChristoph Gysin is a Principal Architect based in Helsinki with 15 years of experience building cloud-native and systems software across startups and large engineering organizations. He combines hands-on expertise in cloud infrastructure-as-code (notably contributions to the AWS CDK) with practical back-end and DevOps work—authoring serverless examples, CI/CD fixes, and scalable deployment patterns. His background spans telecom and cloud firms (Ericsson, Nordcloud, CUJO AI) and includes low-level system work on Wayland compositor tooling, showing fluency from OS-level code to managed cloud services. A self-styled “Cloud Wizard,” he regularly contributes to prominent open-source projects, bridging developer UX, security-conscious IAM handling, and maintainable refactors. Colleagues rely on him to translate complex platform requirements into robust, production-ready architectures while keeping code quality and developer ergonomics front of mind.
