What I'm looking for

I'm looking to help organizations modernize enterprise technology, identity, and digital workplace services while strengthening security, operational excellence, and business value. I value opportunities to advise stakeholders, lead cross-functional delivery, and mentor teams.

At NTT DATA Türkiye, I support BSH Home Appliances Group's Identity & Access Management transformation, helping migrate more than 300 enterprise applications to the Bosch Identity Provider platform. I advise Product Owners and application teams on Microsoft Entra ID, secure authentication, OIDC, SAML, security governance, and architecture compliance.

I also own the Internet Based Client service, enabling BSH employees worldwide to securely access enterprise applications across Windows, macOS, and Linux without a traditional VPN. As Product Owner for Synthesia AI at BSH, I lead enterprise onboarding, governance, vendor coordination, licensing, security coordination, and adoption strategy.

Across Bosal, Renaissance Polat Istanbul Hotel, BilgeAdam, and Atos Origin, I've led IT operations, infrastructure modernization, cybersecurity, service delivery, and technical teams in manufacturing, hospitality, consulting, and technology services. I bring more than 30 years of experience connecting business needs with secure, scalable enterprise technology.
