Hello, world (and why this site exists)

For years I’ve kept notes in scratch files, in Slack DMs to myself, in a ~/braindump.md that nobody but me will ever read. This site is the slow public version of that.

What you’ll find here

• Postmortems of incidents I’ve actually fought — Apache crashing under bot traffic, MariaDB hanging on a stuck MyISAM repair, a /var/backup dir that swallowed a whole root partition.
• Architecture choices I’d defend (and a few I wouldn’t, in retrospect).
• Tools I’m building — mostly around the SysTeam Healthchecks SaaS and the observability tooling that surrounds it.
• Occasional notes on the craft — Postgres tuning, Go gotchas, the long tail of operations work that nobody writes down.

What you won’t find

• “10 things every senior engineer should know” listicles.
• Hot takes about frameworks.
• Anything ghostwritten by an AI without saying so.

If the cursor below is still blinking, the site is live. The first real post should land within a couple of weeks.
