Linux Administrator | Red Hat, CentOS, Ubuntu | Automation with Ansible & Bash | Reducing Setup Time & Maintaining High Uptime

About

I’m a Linux System Administrator with 1+ years of hands-on experience managing RHEL, CentOS, and Ubuntu servers in training and production environments. Since 2025, I’ve focused on system stability and efficiency — consistently achieving over 98% uptime for lab servers while designing automated user provisioning systems using Bash and Ansible. This has helped reduce manual setup time significantly and allowed teams to focus on more important tasks. Currently working as an Information Technology Instructor at NetTech India, I enjoy teaching practical Linux skills and also take up freelance administration and training projects. I’m passionate about automation, cloud solutions, and helping organizations keep their infrastructure reliable. If you're looking for a dependable Linux Administrator who can manage servers efficiently, implement automation, or train teams on Red Hat technologies, I’d love to connect! Open to full-time, hybrid, or freelance opportunities in Mumbai and remote. Let’s talk about how I can support your infrastructure needs.
