What I'm looking for

I seek fully remote roles in systems/cloud administration emphasizing automation, security, scalability, and cross-timezone collaboration.

I am a systems administrator with over five years managing enterprise IT infrastructure, cloud environments, and secure backend systems. I focus on reliability, scalability, and operational efficiency while supporting large-scale user environments.

My experience spans Linux and Windows Server administration, Google Workspace and Microsoft 365 management, and cloud basics with AWS/GCP. I have reduced security incidents through policy improvements and automated backup and monitoring workflows to enhance recovery and reliability.

I have supported and developed backend systems, including a Laravel-based staff portal serving a 75K-user database, and worked on migrations toward cloud-based services to improve performance. I also perform blockchain transaction investigations and digital-asset risk management for private clients.

I am remote-ready, experienced across time zones (notably GMT+7), and seek roles where I can apply systems engineering, automation, and security research to drive operational improvements.
