I am a Cloud FinOps, Microsoft, and AWS Certified professional with 16+ years of experience helping businesses migrate, secure, and optimize their IT infrastructure across both cloud and on-prem environments.
🔘 Email Migration & Microsoft 365 (Office 365)
I provide seamless email migration from Google Workspace, cPanel, Zimbra, GoDaddy, or on-prem Exchange to Microsoft 365 / Exchange Online. I ensure zero data loss, smooth DNS cutover, and complete post-migration validation.

I also support tagging strategy, cost allocation reports, and budgeting to improve visibility across teams.
I provide ongoing monthly cost optimization and reporting using tools such as AWS Cost Explorer, CUR (Cost & Usage Report), CloudWatch, and automation.
Key FinOps Services Include:
* AWS cost audit & waste reduction
* Reserved Instances & Savings Plans strategy (purchase + management)
* EC2 / RDS / EBS rightsizing and optimization
* Auto-scaling and workload scheduling (dev/test shutdown automation)
* Tagging compliance & cost allocation reporting
* Monthly savings reporting and forecasting
🔘 Cloud Migration & Infrastructure Setup
I provide end-to-end cloud migration for websites, applications, and servers — from shared hosting or VPS to AWS, Azure, Google Cloud, DigitalOcean, or Linode.
* AWS: EC2, RDS, Route 53, S3, IAM, Load Balancer, SES, WorkMail
* Azure: Azure AD, Virtual Machines, and resource management
* CI/CD pipelines, Auto Scaling, and backup automation
🔘 Windows Server & Active Directory
I have deep expertise in Windows Server administration, domain management, and security hardening.
* Active Directory, DNS, DHCP, Group Policies, BitLocker, SCCM
* File servers, IIS, WSUS, and RDP services
* PowerShell automation and Intune MDM
🔘 Security & VPN Solutions
I implement secure VPN solutions (OpenVPN, IPsec), SSL certificates, firewall rules, and server hardening best practices to protect enterprise systems and communication.
🔘 Web & Application Migration
I have migrated thousands of websites and applications, including WordPress, Joomla, Magento, Laravel, Node.js, Python, and more.
