Dev Prakash J.

I fix the IT and email problems others escalate. 18+ years in enterprise IT and managed services, with 3,000+ hours delivered on Upwork at 100% Job Success. Most of that career has been Tier 3, the engineer who picks up the ticket after Tier 1 and Tier 2 have run out of ideas. Where clients hire me: → MICROSOFT 365 & GOOGLE WORKSPACE Tenant setup, on-prem and tenant-to-tenant migrations, Exchange Online mail flow, SharePoint permissions, Intune, licensing cleanup. Cutovers planned so nothing is lost during the window. → EMAIL DELIVERABILITY & DNS SPF, DKIM, DMARC, DNSSEC, custom tracking domains, blacklist delisting, and Google Postmaster and Microsoft SNDS diagnostics. I also build and operate an email infrastructure platform, so domain reputation and inbox placement are daily work for me rather than an occasional ticket. → BACKUP & DISASTER RECOVERY MSP360, Vembu, SolarWinds, and Datto Backupify across local, cloud, and Microsoft 365 workloads; including the part most people skip, which is testing that the restore actually works. → INCIDENT RESPONSE Live ransomware containment on production Hyper-V hosts: isolation, triage, clean restore from verified backups, and hardening so the same entry point isn't used twice. → NETWORKING & FIREWALLS SonicWall, Sophos, and UniFi. Site-to-site and WireGuard VPNs, MTU and subnet collision issues, VLAN segmentation, and the diagnostics to show exactly where traffic is dying. → MSP TIER-3 COVER I plug into the stack you already run: ConnectWise, Autotask, SyncroMSP, Datto RMM, Kaseya, IT Glue. No migration required and no ramp-up billed to you. How I work: I document what changed and why; I tell you when something is out of scope instead of guessing at it, and I close tickets without being chased. I keep working during overlap with US and EU business hours. Send me the one nobody else could figure out.
