Top SchoolOlger Warnier is a seasoned CTO and founder with 13+ years building cloud-native, auditable systems and a long track record in the electric vehicle (EV) sector since 2009. He helped create Shell Recharge’s core CPO/MSP platforms, co-authored key open standards like OCPI and contributed to OCPP 2.0, blending deep protocol knowledge with pragmatic product delivery. As founder of Cafienne and CTO Solutions at CaseFabric he focuses on CMMN-based case engines and developer-oriented frameworks that speed Domain-Driven Design delivery using Scala, Rust, TypeScript and Akka. He advises and embeds fast-flow, test-driven architectures in organizations as an interim CTO, and remains active in LF-Energy and open-source projects. Based in Utrecht, he combines hands-on engineering with organizational design, often translating regulatory and market complexity into interoperable, production-ready platforms. A less obvious strength is his consistent emphasis on auditable, data-driven automation across both energy and public-sector care platforms.
