HI, I'M
CRDO.
I BUILD
THINGS
FOR THE WEB.

Full-Stack Developer

Professional code. Terrible drawings. I build web apps end to end and host them myself — this site just happens to look like it was drawn with a cheap mouse.

ABOUT ME

Portrait avatar of Ricardo Jr.

← that's me. yes, really.

↑ probably debugging

Full-Stack Developer. I build the frontend, backend, and database for small web apps — React and Next.js up front, PHP and MySQL behind it — then run them with Docker, Nginx, and Cloudflare tunnels.

I run my own homelab (a Proxmox box with Ubuntu VMs and Docker Compose) so my projects live somewhere real, not just in a demo.

  • Web apps end to end — React, Next.js, PHP, MySQL
  • Runs on my homelab — Docker, Nginx, no open ports
  • Self-hosted infra: Proxmox · Docker · Nginx · Cloudflare tunnels
  • Real users: students, residents, clients

HOMELAB DIAGRAM

Drawn badly. Understood easily. This is the shape of the lab, simplified into a doodle (not a live dashboard).

THE TERMINAL

A real frontend interaction, no backend. Type help. It works on mobile too, tap a chip.

07 · engineering notes, taped to the wall

BLOG SCRIBBLES

Homelab guides I wrote while setting up my own lab. Readable, I promise, unlike my handwriting.
