About Me

Hi, I’m Vignesh — a cloud engineer passionate about scalable infrastructure, DevOps problem-solving, and end-to-end automation. I work extensively across AWS and Azure, often blending observability, security, and deployment best practices into real-world architectures.

Outside of the terminal, I enjoy running, lifting weights, and spending time exploring gadgets and photography. This blog is where I share technical insights, hands-on guides, and the occasional detour into the things I enjoy outside the terminal.
