rdu9/README.md

Backend and infrastructure engineer, mostly in Python.

I build APIs with FastAPI and Postgres, and I'm working my way down the stack: Linux internals, containers, Kubernetes.

Live: discord2.xyz. A realtime chat app inspired by Discord, self-hosted on a DigitalOcean droplet behind nginx and Cloudflare.

Latest project: pastebin. A pastebin with image uploads, deployed on my own Kubernetes cluster: TLS, autoscaling, network policies, and zero-downtime rollouts I measured under load.

Latest write-up: private-service-access. I put a private service behind WireGuard, then found nginx still serving it publicly after an unrelated container went down.

Working with: Python · FastAPI · Kubernetes · PostgreSQL · Redis · Celery · Docker · Linux · nginx · WireGuard
