About

This is fidelitas.io — an anonymous technology blog.

The posts here are about the systems we build to keep complex software honest: distributed architectures, performance engineering, developer tooling, and the boring-but-important glue that makes them all hold together. The writing leans technical, but it’s written for readers, not crawlers.

Why anonymous

Three small reasons, one big one.

• The work should stand on its own. If an argument needs the author’s resume to feel credible, the argument is bad.
• The internet has plenty of personal brands already; it can spare one more from the pile.
• Most of the lessons here come from real production systems at real companies. Anonymity makes it easier to be honest about what actually happened.

And the big reason: it’s more fun to write without a face on it.

Why this exists

There are two kinds of technical writing on the open web:

1. Marketing copy disguised as engineering.
2. Engineering writing that actually changed how you think.

This blog is an attempt to keep adding to the second pile.

What you’ll find here

• Deep dives — long-form explanations of how something works, with the trade-offs left in.
• Field notes — short posts from production, the kind you wish you’d read before the incident.
• Tooling — opinionated reviews of the things on a working engineer’s $PATH.
• Essays — occasional musings about software craft, hiring, and where the industry seems to be drifting.

How it’s made

This site is a hand-built Jekyll theme. Static-only, no JavaScript framework, no analytics, no tracking. Dark-first design, with a light mode for the heretics. Code blocks use Rouge with a custom syntax theme. The whole stylesheet weighs in under ~25 kB.
