01 — ABOUT

I build tools that make complex systems easier to run, observe, and understand.

I’m a software engineering student and GitHub Campus Expert focused on backend infrastructure, Linux internals, containers, automation, and distributed systems.

I like working close to the boundary between application code and the machine beneath it: schedulers, runtimes, storage engines, networks, deployment systems, and the tooling that keeps them dependable.

Cloudflare · Kubernetes · GitOps

A live topology of the stack I actually run.

The diagram maps the same layers I use in my homelab and deployment flow: Cloudflare at the edge, Kubernetes clusters in Sydney and the US, Argo CD for GitOps, Harbor for images, Traefik at ingress, Signoz for visibility, and the storage systems underneath.
