Short, opinionated notes on AI/ML in production — the unglamorous side: cost, latency, failure modes, what actually works at scale. Not prompt-tip threads, not "agents will replace…" speculation. The senior engineer's read.

How often will you publish?

Cadence over polish. Aim for at least one note a week. Some will be 200 words, some 2000. Whatever the topic deserves.

How do I follow along?

Subscribe via the email form (best — you'll get every note in your inbox), follow on X for shorter takes, or just bookmark /notes/ and check in.

Are you open to sponsored posts or partnerships?

Yes — selectively. I only cover tools I actually use in production. See /sponsor for current slots and what I'll and won't take. Reach out via /contact if there's a fit.

Why /notes exists: AI in production, not in pitches.

This is the placeholder while the engine settles. The real content starts next week.

The short version: there are too many AI takes from people who haven't shipped. I've been building backend systems for ~12 years, doing data infra and ML systems for a chunk of the last two. There's a gap between the hype and what production actually feels like. These notes try to close it.

If you build, ship, and operate things that have to keep running — not just demo well — this is for you.
