Naveen P.

Senior System Administrator specializing in Microsoft 365, Active Directory, AWS, and enterprise infrastructure reliability.

For the past 4 years, I've been the sole infrastructure consultant supporting production systems for Revalize LLC (USA), managing customer-facing enterprise environments where downtime directly impacts revenue.

Alongside this long-term enterprise infrastructure ownership, I've delivered migration and remediation projects for 20+ organizations across SaaS, manufacturing, and professional services.

Core expertise:

• Microsoft 365 migrations & hybrid Exchange
• Active Directory & Windows Server administration
• AWS cost optimization & infrastructure reliability
• PowerShell automation & process optimization
• Disaster recovery & business continuity

Clients typically bring me in when:
→ Migration projects have stalled or lack expertise
→ Active Directory or mail infrastructure becomes unstable
→ Production environments lack documentation or monitoring
→ Infrastructure costs are growing unexpectedly
→ Internal teams cannot safely troubleshoot production systems

Recent project outcomes:
→ Migrated 500+ users from Exchange 2016 to Microsoft 365 with zero email downtime during 72-hour cutover
→ Reduced AWS infrastructure costs by 30% ($47K annually) through EC2 rightsizing and Reserved Instance strategy
→ Restored multi-site Active Directory replication affecting 450+ users across 3 locations within 8 hours
→ Recovered a non-booting domain controller with SYSVOL/DFSR failures in 6 hours, preventing an authentication outage
→ Automated user onboarding workflows, reducing provisioning time from 2 hours to 10 minutes
