Paulino N.

I design and run Microsoft infrastructure for companies that can't afford downtime: Azure landing zones and migrations, Microsoft 365 and Intune, Entra ID, and the Citrix and VMware platforms underneath. 15+ years in enterprise IT, working as a senior architect for US and global enterprise clients, with 2,300+ hours and 100% Job Success here on Upwork. What I do most often: - Azure: landing zones (hub-and-spoke, policies, cost controls), server and application migrations, low-level designs, DR copies. - Microsoft 365: tenant migrations (Google Workspace and tenant-to-tenant), Exchange Online, SharePoint and Teams, Intune device management, Entra ID and Conditional Access, Windows 365 and Azure Virtual Desktop. - Virtualization: VMware vSphere, Hyper-V and Nutanix AHV builds and upgrades, Citrix Virtual Apps & Desktops and NetScaler/ADC. - Power Platform: Power Apps, Power Automate and Copilot Studio solutions, with the governance to run them. How I work: discovery first, a written design you can challenge, pilots before cutover, rollback for every change, and documentation your team can actually run from. I'm in Mérida, Mexico (UTC-6, US Central hours), bilingual English/Spanish. If you're planning a migration, cleaning up a tenant, or need an architect to own a design end to end, send me a note and I'll tell you how I'd approach it.
