What I'm looking for

I’m looking for a role where I can own end-to-end IT support and systems administration—secure access (SSO/MFA), reliable troubleshooting, and practical automation—while collaborating with international teams and continuously improving cloud and on-prem operations.

I’m currently an IT Helpdesk Technician / System Administrator (since 2024), supporting internal users both remotely and in person. I administer Google Workspace (via Google Admin Console), manage Shared Drives and role-based access controls, and handle onboarding/offboarding with precise account provisioning and access changes. I troubleshoot Windows and macOS endpoints and assist with on-prem infrastructure tasks like printers and basic network connectivity.

Previously, I worked as a Cloud Operations Engineer (2023–2024), delivering engineering support across UK, US, and SEA clients. I managed support tickets within SLAs, monitored cloud and on-prem infrastructure for hedge fund and financial clients, and operated client environments as well as internal infrastructure. I also supported Microsoft Azure cloud environments and Active Directory / Office 365 back-end, while developing automation tools to improve efficiency.

From 2021 to 2023 as a System Engineer, I designed and maintained IT infrastructure including virtualization environments using VMware vSphere and Microsoft Hyper-V. I configured Active Directory, Group Policy, and IAM systems, implemented backup and disaster recovery strategies, and strengthened security with patch management, firewalls, intrusion detection/prevention, and encryption. I automated repetitive processes using PowerShell, Bash, and Python, and ensured compliance with regulations including GDPR, HIPAA, PCI DSS, and ISO 27001, while mentoring junior team members.

Earlier roles (2012–2020) built my foundation in hands-on IT support and system administration, from maintaining servers and VPN configurations to resolving helpdesk tickets and training end users. I coordinated with vendors, documented IT policies and procedures, and ensured system security through vulnerability scanning and patching. Throughout every role, I bring strong problem-solving, attention to details, and clear communication in fast-paced, international environments.
