Field CTO at Zenika
Greater Rennes Metropolitan Area France
Summary
👤
Senior🎓
Top SchoolLE LAY Olivier is a versatile Field CTO and technical leader with over a decade of experience delivering web and mobile solutions, blending hands-on development with client-facing consulting and training. Rooted in an Android developer background and an INSA Rennes engineering degree, he brings a UX-sensitive approach to multi-resolution front-end work (Angular, Vue, Ionic) and solid backend skills (Node.js, Python). He specializes in full delivery lifecycles and CI/CD tooling—GitLab/GitHub Actions, Kubernetes, GCloud, Docker—preferring to understand and influence the entire stack from code to deployment. A seasoned coach and trainer at Zenika, he combines technical depth with mentoring and near-shore management, making him effective in audits, rewrites, and strategic modernization projects. Less obvious: his career blends long-term hands-on engineering (a decade at Groupe SII) with an evolving leadership footprint that still prioritizes practical tooling and developer experience.
