What I'm looking for

I’m looking for a global remote job role where I can design and modernize secure cloud and/or on-prem infrastructure, define standards and security policies, and deliver reliable 2nd/3rd line support—collaborating with teams and partners to ensure business continuity.

I’m a versatile IT Systems Engineer with over 15 years of experience designing, implementing, and supporting enterprise IT infrastructure across cloud, server, networking, and end-user computing. I focus on modernizing environments and delivering secure, resilient solutions that support business continuity.

In my current role, I design and maintain cloud infrastructure, define infrastructure standards, security policies, and operational procedures, and plan modernization projects. I implement security controls and compliance measures, coordinate external providers and technical partners, and provide 2nd/3rd line support for cloud and on-premises infrastructure.

Previously, I administered server infrastructure, virtualization, backups, networking, and firewalls, while managing Microsoft Active Directory, DNS, DHCP, and Group Policy. I’ve also led an IT QualityAssurance team, supported system integration projects, and served as a Certified Vocational Trainer—bringing both technical depth and a practical mindset to team success.
