About Me

Hi, I'm Keerthivasan Krishnamoorthy from Bengaluru, Karnataka.

I am an inquisitive Computer Science Engineer specializing in IT Infrastructure, Systems Administration, DevOps, and Vibe Coding. I blend a deep understanding of core network routing and server security with automated shell scripting, modern container orchestration, and vibe coding practices.

Currently, I work as an IT Infrastructure Support Engineer at FCOOS Technologies, administering Windows Server environments, Active Directory domains, Microsoft 365, and firewall/VPN networks. I focus on optimizing server performance, scheduling secure backups, and engineering reliable infrastructure solutions.

My philosophy? Automate the repetitive, monitor everything, and build secure, resilient architectures that prevent downtime before it happens.
