AI, explained by anengineer who builds it

I'm Endi, an engineer. I show you what AI can actually do for your business, and what it can't, by building it live instead of talking about it.

Three things I make,
all in one place

Nothing here that I haven't run on my own machine first.

Watch it get built, then why

Full walkthroughs where the thing actually gets made: Claude Code, MCP servers, agent pipelines. The result comes first, then I open the hood and show you the part that made it work.

Take a look

BeginnerClaude Code

Your first CLAUDE.md: the four boundaries that matter

IntermediateMCP

Wiring your first MCP server (and locking it down)

AdvancedAgents

A model router that stops you burning usage limits

Three problems almost everyone has

Fix them in this order. Each one is an evening, and each one stops a thing that's quietly costing you every day.

After those three, the order stops mattering. Take whatever you need.

What people say

In their words.

wait the whole file is 12 lines?? mine is like 300 and it still ignores half of it

DESIGN 🙏

commenting so i can find this again later

ok i was sceptical about the routing thing but it actually worked. no more running out at 2pm

does this work with cursor too or is it claude code only

not you fixing in 8 min something ive been fighting for a month 😭

finally someone showing the actual file instead of just talking about it

One build a week

What I made, what broke, and the file you need to do it yourself. Nothing else in the email.
