What I'm looking for

I’m looking for a role where I can own identity and access processes, strengthen ISO 27001-aligned security, and automate IT workflows using Azure and AI to improve SLA performance and service reliability.

I’m an IT Support and Identity & Access Management (IAM) professional with 5+ years of experience across financial services, healthcare, and automotive. I deliver Level 1 and Level 2 technical support, administer user lifecycle processes (provisioning, deprovisioning, access reviews), and automate identity workflows—achieving a 60% reduction in ticket response times.

I bring hands-on expertise with Azure Active Directory (Entra ID), MFA, VPN administration, ServiceNow, ManageEngine, and SIEM tooling, plus ISO 27001:2022 and COBIT 2019 credentials. I also help teams maintain audit-ready security posture through ISMS work aligned to ISO 27001:2022 and NIST Cybersecurity Framework, and I streamline IT operations with AI-assisted workflow automation using Claude, ChatGPT, and n8n—always collaborating closely across cybersecurity, infrastructure, and development to keep services reliable.
