Build LLM Apps from Zero to Hero — the complete, hands-on path from "what is a token?" to designing, evaluating, and shipping a real Generative AI system.

Most courses teach Generative AI in disconnected toy examples. This one grows a single real product across every section, so your skills compound instead of resetting. You'll build Sage — a production-shaped AI assistant for the fictional startup Brightpath — one layer at a time, ending with a system that retrieves from private docs, uses tools, generates content, is evaluated and secured, and runs in production.
Each section ends with a hands-on checkpoint that adds a concrete capability to Sage. Along the way you ship seven standalone projects plus a capstone, and every section closes with a quiz so you can check your understanding before moving on. A final assessment ties the whole journey together.
Developers and technical builders who want to go from curiosity to competence in Generative AI. You should be comfortable reading basic Python; everything else — prompting, RAG, agents, fine-tuning, multimodal, evaluation, deployment — is taught from the ground up.
System Design & Distributed Systems · 14 yrs · Ex-Amazon, Staff Engineer
Marcus has spent 14 years building the kind of distributed systems that quietly run the internet — order pipelines, multi-region data stores, and the boring-but-critical plumbing in between. He led capacity and reliability work on systems serving hundreds of millions of users at Amazon, and now teaches the trade-offs behind the diagrams, not just the diagrams themselves.
Very good overall. The fundamentals are explained clearly, though some examples felt slightly dated.
The best money I have spent on learning this year. Clear, modern, and no fluff.
Clear and practical. Most of it was excellent; one or two lessons could use a refresh.
Some solid moments, some filler. Worth it on a discount, perhaps not at full price.
