Samuel McDonnell

I’m an AI engineer. I build and ship production AI systems, agentic chatbots, eval harnesses, the observability that keeps them honest. This account is where I write about what actually works in production vs what gets hyped on here. The boring engineering that makes AI reliable, not the demos. Follow along if you build real things with this stuff.

@thebruchez Spot on

@samueljmcd Yep, the build is cheap, the maintenance bill is the part people ignore.

Everyone’s shipping AI-built apps in a weekend. But nobody’s costing who maintains them in 18 months when no one understands what was built. That bill lands around 2027.

@TTrimoreau Bro this is inspiring, I didn’t even know you could make money like that from X… I presumed it was 200 dollars for like 50k followers 😂 Does the type of niche you post about affect how much you get paid would you know?

This is what I’ve earned on X so far. I started on January 27… and in 4months and 1 week. I’ve already made $6,481.14 . That’s honestly insane.

What’s the most useful Claude Skill you guys have built?

@DanielSmidstrup Awesome sauce

@stemonteduro 😂😂

Only 2.5% of AI job postings are open to people with under two years of experience. Read that again - 2.5% !!! We spent a decade telling people to learn to code, then built a market with no entry door. This isn’t AI taking jobs. It’s AI eating the entry point - the exact one everyone used to climb to get good! The seniors of 2032 were supposed to come from the juniors of 2026. Nobody’s hiring them. We’ll feel this in about four years.

@astitva004 Thank you bro!
