Summary
Stephen Oostenbrink is a seasoned technology leader and principal consultant specializing in AI, enterprise architecture, and large-scale transformation, with over 25 years of experience across public, energy, and utilities sectors. He has repeatedly translated strategic vision into engineering reality—most notably as CTO at EDSN, where he led the shift from outsourced operations to an in-house engineering organization, scaling teams from 2 to 25 and building a 10+ architect practice. Stephen blends platform thinking, cloud-native modernization, and DevSecOps with pragmatic governance to deliver secure, compliant, and resilient digital capabilities that support the Dutch energy transition. He now advises executive teams on responsible AI adoption, operating model design, and rapid AI validation through an AI Innovation Hub that he helped establish. Known for making technology governable without bureaucracy, he thrives in complex multi-stakeholder environments where strategy, delivery, security, and talent must align. His background as a founder and long-term interim advisor gives him uncommon fluency in both hands-on delivery and board-level strategy.
