sdet by day · homelab by night

I break software on purpose so it doesn't break by accident. After hours I run a server rack in my house and build factories I never quite finish.

What I do for a living

Software Development Engineer in Test

I build the test automation for an Angular app: UI and API suites in Playwright, built on custom fixtures and page objects, plus some load testing with Artillery. I'd rather a test catch it than a customer.

The homelab is where I practice the same habits on my own systems: automate it, monitor it, write it down.

// stuff i do

Things I spend too much time on

The homelab

An old enterprise server, a pile of containers, a NAS, and a UPS that's the only thing standing between me and a very bad day. Media, cloud storage, game servers: if I can host it myself, I probably am.

Dungeon master

Running a homebrew 5e campaign for my friends on a self-hosted virtual tabletop. No regrets.

3D printing

Bambu X1-Carbon with 8 filament slots. Mostly rack gear and enclosures, like a custom case for the Pi that rips my Blu-rays.

RC & FPV

A Tinyhawk II for flying indoors, and an Arrma Gorgon monster truck, fixed up and ripping on fresh tires.

Gaming

2,271 hours in Satisfactory

Plus Factorio and Dyson Sphere Program. An SDET who automates for fun? Shocking, I know.

// how i run it

Run like production, just smaller

TLS on everythingOne reverse proxy in front, real certificates, nothing served in plain text.
Admin stays insideManagement tools only answer to the local network or the VPN.
MonitoredEvery service has an uptime check, and the alerts only fire when something's actually down.
Backups get testedVerified, not assumed. A backup you haven't restored is a rumor.
Power-awareWhen the UPS runs low, everything shuts down gracefully, in order.
Written downEvery host and service has a note in Obsidian, because I won't remember.

Stockpile

A small, single-binary web UI for LanCache with prefill scheduling and a "Doctor" page that catches the usual gotchas. Go + SQLite.

The campaign

A homebrew 5e campaign world for my friends. No spoilers.

A spare Pi that runs a morning health check on the lab and pings my phone only if something's broken.
