What I'm looking for

I’m looking for fully remote roles where I can lead secure Linux/DevOps operations, automate deployments and incident response, and strengthen AWS/Azure reliability using CI/CD, monitoring, and security-first practices in a collaborative team.

I’m a results-driven Linux Administrator and DevOps Engineer with 2+ years of hands-on Linux & systems experience, managing production servers and cloud infrastructure across AWS and Azure. I focus on security, stability, and fast incident resolution—keeping environments dependable under real-world pressure.

In my current role, I administer Linux app, database & backup servers for enterprise clients and maintain a Security 99%+ uptime SLA. I debug and resolve critical incidents like service failures, disk saturation, and process hangs while minimising MTTR, and I deploy hotfixes and emergency patches on live systems with zero unplanned downtime.

I build and support multi-tier server infrastructure (app/DB/backup layers) under SLA-driven timelines, and I’m actively strengthening my automation and delivery workflow using Docker, Kubernetes, Ansible, and CI/CD. I also apply AI-assisted prompt engineering to accelerate root-cause analysis and documentation—without compromising operational discipline.

I’m RHCSA v9 certified and have Azure-focused experience from building and managing cloud resources, including VNet configuration, provisioning, and performance monitoring. I’ve also worked on cybersecurity outcomes—using Wireshark, Nmap, Metasploit, and OWASP testing—backed by digital-forensics and penetration-testing exposure through my B.Tech work and internships.
