Over mij
IT infrastructure and security engineer with 15+ years of experience. I help small and mid-size businesses with Microsoft 365 and Google Workspace migrations, email authentication (SPF, DKIM, DMARC) and DNS repair, and office networks built on Ubiquiti UniFi and business firewalls. Recent work includes consolidating 4 Microsoft 365 tenants into one for about 120 users and moving 4 domains to Google Workspace. You get a clear scope before I start, updates as I go, and written documentation when I finish. I work in English and Spanish.
