What I'm looking for

I seek a hands-on cybersecurity role focused on IAM/IGA and SOC operations where I can apply access governance, incident response, and directory services skills while growing in a collaborative, security-first team.

I am a cybersecurity specialist with hands-on experience in Identity & Access Management (IAM), Identity Governance (IGA) and practical exposure to Security Operations Center (SOC) processes. I have implemented IGA lifecycle management with Aveksa, led access review campaigns, administered Oracle Internet Directory, and resolved SSO and MFA authentication issues to improve access reliability.

I have supported security monitoring, alert triage, and incident investigations within SIEM workflows and collaborated with SOC and IT teams on detection tuning and operational resilience. My background includes on-site and remote infrastructure security, firewall and network device deployments, and vendor coordination across enterprise environments.
