About Me

Engineering philosophy, background, and core focus

Profile // Bio

I am a Senior IT Infrastructure and Cloud Engineer with more than 12 years of enterprise engineering experience specializing in Modern Workplace architectures, Microsoft Intune administration, and PowerShell automation.

Throughout my career across enterprise client engagements, I have focused on solving the real-world friction between strict information security and seamless end-user productivity. My work centers on transitioning legacy on-premises environments into cloud-native, zero-trust architectures—utilizing Windows Autopilot for zero-touch provisioning, Microsoft Entra ID for identity governance, and automated Microsoft Graph PowerShell scripts to eliminate manual operational overhead.

Autonomous Modern Workplace & Zero-Trust Fleet Migration

60% Faster Staging Enterprise Fleet

Architected the complete transition from legacy on-premises SCCM/co-management to cloud-native Microsoft Intune and Entra ID across international operating environments. Deployed Windows Autopilot zero-touch provisioning pipelines, hard-enforced CIS endpoint baselines, and implemented automated Microsoft Graph PowerShell scripts for hands-off tenant drift management.

Key Challenge
High device staging turnaround, dynamic group sync delays, and legacy GPO drift.
Delivered Outcome
Under 20-min zero-touch provisioning, cloud LAPS key escrow, and automated compliance sync.

Enterprise Hybrid Infrastructure & Data Center Modernization

99.9% Core Uptime Data Center / Cloud

Maintained and modernized high-availability hybrid infrastructure spanning on-premises data center compute, VMware vSphere virtualization clusters, and Azure IaaS resources. Coordinated Active Directory consolidations, identity federation, hardware maintenance life cycles, and disaster recovery readiness.

Key Challenge
Siloed directory structures, aging hardware racks, and complex hybrid authentication paths.
Delivered Outcome
Streamlined Kerberos hybrid joins, resilient Azure virtual networking, and audited SLA compliance.

Cross-Platform Mobility & Automated Deployment Architecture

Zero-Data Leakage Multi-OS Fleets

Designed multi-tier OS deployment pipelines (OSD), software packaging workflows, and ring-based patch management policies. Implemented containerized Mobile Application Management without enrollment (MAM-WE) across personal mobile devices, preventing corporate data leakage while maintaining full end-user privacy.

Key Challenge
Unregulated mobile access risks, uncontrolled software distribution, and update fragmentation.
Delivered Outcome
Automated update rings, biometric MAM sandboxing for iOS/Android, and audited software packages.
