Gerben De Graaf is a seasoned technology leader and current CTO based in Utrecht, with 13 years of leadership experience and a 15-year developer background building web, native, game and B2B systems. He specialises in turning business goals into practical, auditable technical roadmaps—most recently steering Agentic AI for mortgage origination at Oper Credits—and excels at assembling high-performing agile teams that bridge product, process and engineering. At Backbase he scaled engineering for banking platforms and Backbase-as-a-Service, blending domain-savvy delivery with a data-driven approach to prioritisation and measurable outcomes. His early career in real-time multiplayer platforms and payments APIs gives him deep hands-on credibility across complex distributed systems. Colleagues describe him as a pragmatic champion of technology-led change who knows that lasting transformation depends on individual commitment as much as architecture.
