Yusuf Ismail Oktay

I'm a software engineer with over two decades of experience shipping software that matters. My background includes leading development teams for a super-app with 35M+ users at Ayoba. Orchestrated multiple teams delivering high-scale microservices, messaging, and web platforms on AWS, telecom architectures at Ericsson and Turkcell, fintech leadership at ViaBill, and enterprise modernization at AvivaSA and Rabobank.

Today, I run YiokAI, a product studio building across three distinct domains:

  • Consumer: Immersive discovery tools like TubeTrail.
  • Enterprise: Critical infrastructure for aviation and telecom, including Flight Personnel Apps and LLM Gateways.
  • Agent-Native: The missing layer for AI agents, from Gatekeeper authentication to secure networking.
