Transforming complex infrastructures into secure, predictable, and automated operations, connecting hybrid environments, IAM, governance, and business continuity.
visitor@tkusal:~$ cat ./about.md
More than just keeping the infrastructure running, my focus is on building secure, automated environments designed to support your business growth and continuity.
I have worked in IT infrastructure for more than 15 years, from server administration to leading teams and projects across hybrid and cloud environments. This experience helps me connect business needs with architecture, security, and high-availability decisions.
Today I modernize legacy environments with DevOps, Infrastructure as Code, and automation, reducing manual work and making changes more predictable and traceable. Identity and security are the foundation: I connect IAM, servers, networks, cloud, and governance in one integrated view.
IAM, Entra ID, Active Directory, Purview, Defender, Zero Trust, SAML, LDAP, and OAuth.
Windows Server, Linux, Hyper-V, VMware, Storage, Hybrid Environments, Azure, Microsoft 365, AWS, and Oracle Cloud.
PowerShell, Power Automate, Python, Shell Script, Terraform, Ansible, Docker, Kubernetes, Git, Pipelines, Standardization, and Continuous Improvement.
I believe knowledge grows stronger when shared. That's why I share my experiences, challenges, and lessons learned on RookieOps and my other channels. Contributing to the community is what connects my hands-on experience to my journey toward becoming a Microsoft MVP.
