I automate IT infrastructure so you don’t have to. With 22+ years of hands-on experience in Windows, Linux, and cloud environments, I’ve built, migrated, and automated everything from on-prem Active Directory forests to full CI/CD pipelines on Azure and AWS. Here’s what I deliver: • CI/CD pipelines (GitHub Actions, Jenkins, Azure DevOps) • Infrastructure as Code with Terraform & Ansible • PowerShell & Python scripting for automation and monitoring • Active Directory migrations, GPO automation, and cleanup (10K+ users) • Cloud deployments (Azure/AWS) — production-ready in < 15 min • Internal dashboards & reporting tools (Python/Django) I focus on reliability, documentation, and automation that actually saves time — not just moves the manual work elsewhere. If you’re tired of firefighting and manual builds, let’s streamline your environment and make it self-healing.
