What I'm looking for

I seek a full-time remote IT support or infrastructure role offering hands-on Windows/network administration, automation opportunities, and collaboration in a team-oriented environment, with afternoon/evening hours to support international time zones.

I am an IT Support Specialist with 2+ years of hands-on experience providing remote and on-site technical support in corporate and industrial environments. I specialize in Windows troubleshooting, network administration, Active Directory, and IT infrastructure management, supporting international users across time zones.

My work history includes managing corporate networks (Mikrotik, TP-Link, Ubiquiti), administering Windows Server environments with Group Policy and automated provisioning, and deploying 50+ Windows 10/11 workstations standardized with Office 365 and corporate security. I have also developed an internal HR module using SQL Server and C++/CLI and am currently building a custom ERP with normalized SQL Server architecture and optimized queries.

I bring bilingual communication (Spanish/English), a proven record of rapid incident resolution and high user satisfaction, and availability in afternoon/evening hours to cover Europe and US East Coast schedules. I seek roles where I can apply infrastructure and support expertise while contributing to process automation and systems reliability.
