_{DevOps Engineer · System Administrator · AWS · Hyderabad}

I’m a DevOps Engineer and Systems Administrator with 7+ years of hands-on IT experience across enterprise Windows infrastructure, Linux administration and AWS cloud.

Started as a System Administrator at Revalsys Technologies in Hyderabad – managing Windows Server, Active Directory and enterprise IT for 3.5 years. Then moved to vSplash Techlabs as a System and Network Administrator, handling both Linux and Windows environments in a hybrid setup.

Currently working as a DevOps Engineer at Ratnam Solutions – building AWS infrastructure, CI/CD pipelines and cloud automation systems. sysadmin.co.in is where I document everything I learn in the field — real problems, real solutions, no fluff.
