Team KT — knowledge transfer

Your seniors, handing over what they actually know.

When you join a real team, nobody hands you a course — a senior sits you down for KT. Short, plain-language sessions: what each concept is, how it breaks in production, and what you tell the AI when you build it. The full map is below; sessions unlock as they’re recorded.

The honest answer — and the one skill that still pays.12:47Foundations · Start here — FoundationsGit & GitHub — where your code livesAI writes the code, but it won’t run your workflow. All of Git & GitHub in plain English — commits, branches, pull requests, merge conflicts — plus the leaked-secret mistake that ends careers.4:59Session 1 · D1 · Identity & AccessAuthenticationAsk AI to build a login and it works — until a 15-line script tries 10,000 passwords and walks in. Here’s every part of authentication AI skips, and exactly what to tell it.
