Professional Summary
An accomplished, enterprise-grade IT Manager and Infrastructure Consultant with over a decade of experience driving technical strategy, cloud migrations, and operational excellence. Currently serving as a corporate Assistant IT Manager, I specialize in architecting scalable solutions, managing complex cloud environments (AWS Console), and administering global enterprise workspaces (Google Workspace) for 150+ international properties and over 3,000 corporate endpoints.
My consulting framework focuses on three pillars: IT infrastructure automation, strict compliance/standardization, and strategic cost reduction. I bridge the gap between high-level business logic and hands-on technical execution.

IT Infrastructure & Architecture: Hybrid network administration (Cisco, MikroTik), UNIX/Linux-based server deployment, virtualization, containerization, and enterprise Domain Controller management.
Compliance & Audit Leadership: Designing and executing comprehensive IT audits, implementing standard operating procedures (SOPs), and securing ISO 9001 compliance.
IT Automation: Eliminating operational friction by engineering custom automation tools via Google Apps Script and modular scripting.
Proven Career Highlights & Achievements
Enterprise Cloud Migration: Successfully spearheaded the large-scale migration of legacy corporate email systems from Outlook to Google Workspace.
Infrastructure Transformation: Migrated mission-critical Windows-based operating systems and Microsoft SQL Servers to robust, open-source Linux environments, drastically reducing licensing overhead.
Multi-Property IT Management: Directed technical support, standardization, and remote IT consultations for a massive hospitality footprint spanning more than 150 properties globally.
Compliance Excellence: Secured and maintained ISO 9001 certification for the IT department multiple years in a row by drafting rigid standardization policies.
