How to really work with AI agents.

I'm Isma. I show you how a real team codes with AI agents, at a company and on my own infrastructure. No hype, always with numbers.

What I talk about

No chapter-by-chapter tutorials. Real work.

Laravel is still my lab. What I share is how decisions get made, what they cost and what breaks.

  1. 60%

    AI in production, with numbers

    How a dev team works with agents: cost, PRs, lead times and the bugs that slip through.

  2. 25%

    Your own AI in the homelab

    Local models vs. the API: power, hardware, speed and quality, all measured.

  3. 15%

    Dev decisions in the age of agents

    Which plan to pay for, which stack to pick, and which senior judgement matters more than ever.

Cohort · February 2027

Something is cooking for February.

A small cohort to bring AI agents into a real dev team. Details drop in December, and people on the list get in first and pay less.
