About Devops Tahina

I’m Tahina Rakotomaharo, a DevOps and Systems Engineer with over 9 years of experience in IT operations and 3+ years in DevOps practices. My journey began as a system administrator, managing Red Hat Linux and Windows servers, VMware virtualization, and critical banking infrastructure.
