IAM and Cybersecurity Specialist securing Microsoft environments with 4+ years’ experience in identity lifecycle and audit readiness.
Costa RicaWhat I'm looking for
I’m an IAM and Cybersecurity Specialist with 4+ years of hands-on experience securing Microsoft environments across Active Directory and Entra ID. I focus on identity lifecycle management (JML), RBAC, and hybrid troubleshooting to keep access accurate, secure, and operational.
At Kyndryl, I’ve driven measurable process improvements by designing a globally adopted VDI automation tool and an IAM Access Repository. These initiatives strengthened audit readiness and helped reduce audit findings while supporting 300+ monthly quality case reviews.
I also support the full identity lifecycle in on-premises Active Directory syncing in Entra ID, including JML on ERPs and over 80 applications, and I administer Microsoft 365 and Exchange Online for mailbox provisioning and escalated troubleshooting. I consistently meet SLA targets through structured workflows—processing 250+ ServiceNow tickets per month and maintaining strong time-to-resolution.
I combine Zero Trust and least-privilege practices with tools like SailPoint and Microsoft Sentinel to improve security outcomes and operational consistency. With AZ-900, SC-900, ITIL v4 Foundation, and SailPoint Identity Security Leader certifications, I bring a fast-learning, detail-driven mindset and enjoy mentoring peers.
