What I'm looking for

I’m looking to lead secure, business-aligned IT operations—owning Microsoft 365, identity (Entra ID), hybrid infrastructure, and Zero Trust—while improving reliability, cost efficiency, and multi-site service continuity through strong governance.

I’m a Senior System Administrator & IT Infrastructure Engineer with 6+ years architecting and managing enterprise-scale environments for 1,000+ users across multi-site operations. I’m especially strong in Microsoft 365, Entra ID (Azure AD), Windows Server, hybrid infrastructure, and Identity & Access Management with Zero Trust and Conditional Access.

Currently, I act as IT Manager, owning incident escalation, vendor governance, service continuity, and infrastructure decision-making across multi-site environments. I’ve driven major outcomes like slashing monthly ISP expenditures by 75% while maintaining 100% service availability, and leading ISO 9001 compliance readiness as IT Document Controller through standardized SOPs and version control on SharePoint Online.

Previously, I’ve delivered greenfield deployments end-to-end—building Active Directory, file services, networking, and operational readiness from day one—while designing enterprise backup and retention using Microsoft Purview eDiscovery to ensure zero data loss. I also centralize and optimize networks (MikroTik and Aruba) for better performance, security visibility, and manageability, and I build durable IT governance through clear documentation, SLAs, and continuous improvements.
