About me

I'm an IT professional with 13+ years in the Microsoft ecosystem, currently specializing in Identity and Access Management (IAM) with Microsoft Entra ID.

My background in infrastructure gives me something most IAM specialists don't have: I understand what happens below the identity layer. I've managed the systems that IAM policies protect β€” which means I design controls that work in the real world, not just on paper.

  • βš™οΈ Building automation with PowerShell and Microsoft Graph API
  • 🌎 Experienced managing identities across Chile, Peru, Colombia and the US
  • πŸ“˜ English B2 β€” comfortable in remote, international environments
