In the AI era,
‘it works’
isn’t enough.
Learn to design, build, and explain agentic architectures.
An interactive AI tutor inside VS Code. No videos. No passive content. Just you, real code, and challenges that prove you understand.
Learn AI engineering from first principles
Active practice in VS Code, not passive content. Every session is hands-on, every concept is challenged, every decision is yours to defend.
Interactive IDE Tutor
A tutor inside VS Code that pauses for your reasoning. Not a video. A two-way conversation where you ask questions, write code, and think out loud.
Explain Trade-offs
Practice articulating architecture decisions as you build. The kind of reasoning that interviews actually test — and that separates engineers from prompt-copiers.
Fluid Defense
The boss fight at the end of every chapter. Prove you understand with questions and coding challenges. No timer, no pressure — just you and the code.
How it works
From ‘I watched it’
to
‘I can build it’ —
fast.
Start
Pick a Fluidcast, hit start, and VS Code opens right in your browser. No installs, no config — your workspace is ready in under a minute.
Learn + Build
Follow along with an AI tutor that adapts to you. Write real code, run commands, ask questions, get challenged — in 15-30 minute chapters.
Defend
At the end of each chapter, prove your understanding in Fluid Defense. Answer questions, solve coding challenges, explain your decisions.

Building AI Agents
from First Principles
Go from calling LLM APIs to designing agent harnesses from scratch. Build, evaluate, and understand agentic frameworks — so you can pick the right one for any use case.
Hi, I’m YourTechBud
I’m a software engineer who’s been building AI systems and teaching on YouTube. I built Fluidcast because I was tired of tutorials that don’t stick — where you watch someone code for 2 hours and can’t explain a single decision afterward.
This is how I wish I’d learned. Active, challenging, inside the tools you’ll actually use. I’m letting people in gradually so I can learn from you too.
