System Design and AI Engineering, by Roni Das. 980 interactive lessons.
Start LearningAI engineering course · MLOps + LLMOps
Most machine learning models never make it to production. The hard part was never the model. It is the system you have to design around it: packaging, serving, pipelines, feature stores, monitoring, evals, and production LLM systems. Interactive, diagram-driven, and built for engineers.

AI Engineering is the second course on systemdesign.academy: 210 lessons in 16 chapters, about 219 hours of reading. It teaches how to build and run AI systems in production: how language models generate text, tokens and embeddings, prompting, RAG, AI agents, evals, fine-tuning, model serving, feature stores, data engineering for ML, packaging and model registries, LLMOps and AI security. Every lesson has Python you can run in your browser, and a quiz. 118 lessons are built on a lab that was really run, and show the terminal recording of that run. It costs ₹999 in India or $49 everywhere else, once, with lifetime access, and 10 of its lessons are free to read with no signup. An AI tutor sits beside every lesson.

What you will be able to do
four things you can do by the end
Take a model out of a notebook and run it as a service that survives real production load
Build training pipelines that retrain automatically, with an evaluation gate and safe rollback
Kill train and serve skew with a feature store, and catch silent model decay with drift monitoring
Ship production RAG and LLM systems: vector search, fine-tuning, guardrails, and agents that do not run away
Beside every lesson
Stuck on a slide? Open the tutor next to it. While you read a lesson, the tutor reads the same lesson and answers from it, in simple English.
Explains
any part of the lesson in simple English, with an everyday example first.
Draws
a whiteboard sketch, a 3D figure, a cloud diagram with AWS, Azure or GCP icons, a sequence diagram, an explainer figure or a cheat-sheet poster.
Quizzes you
one question at a time. The site's own code checks your answer against the tutor's answer key.
Interviews you
a mock interview on the topic, one question at a time, with feedback on your answers.
Without an account you can ask 2 questions a day to try it. A free account gets 5 questions a day. Anyone who owns either course can ask as many questions as they like.
Try the tutor nowReal labs, real runs
Every lesson has Python you can run in your browser, and a quiz. 118 lessons are built on a lab that was really run, and show the terminal recording of that run.
The labs use real data and real models: years of electricity-market and bike-rental records, real shop orders, real tokenizers and embedding models, and small language models running on a laptop.

Each chapter is a focused sequence of visual, interactive lessons. We add lessons regularly, and lifetime access includes every one.

Start from why most models never ship. Packaging, serving, training pipelines, feature stores, registries, monitoring, and a first production RAG system: the building blocks every ML platform is made of.
74 lessons · 6 chapters · about 84 hours
The data and retrieval foundation every model depends on: batch and streaming ingestion, ETL and ELT, lakes and warehouses, validation and versioning, then production RAG and agents that stay reliable under real load.
62 lessons · 3 chapters · about 64 hours
Operating large language models in production: fine-tuning vs RAG, parameter-efficient tuning, the evaluation discipline the industry pays most for, prompt management, inference optimization, guardrails, and agent security.
How it works
Every system is drawn with the real tools you deploy: Docker, Kubernetes, MLflow, BentoML, Feast, Kafka, and more. Not boxes and arrows.
Slide-based lessons with step-by-step animated diagrams, runnable examples, and quizzes with instant feedback. You learn by doing.
Every lesson is technically reviewed for accuracy: real tools, real numbers, real trade-offs. No hand-waving.

It is easy and good
It is really nice and good Please join the course
The concepts were explained in a clear and structured way, with practical examples that made even complex system design topics easier to understand. I especially liked the focus on real-world architecture, scalability, trade-offs. The content was well designed, engaging, and highly useful for anyone looking to strengthen their system design skills. Highly recommended for software engineers preparing for system design interviews or wanting to build a stronger foundation in designing scalable systems.
Outstanding all-in-one source of knowledge, especially excellent practice
Ive started this course by accident - LLM advised me this site. When I passed few free lessons, I had no doubt - this course should be bought. And I did it with special pleasent price and it was best decision of the month. Content is great, interesting to read and with a lot of practial cases (what makes it different from other souces and books) I hope to teach all the lessons, that will be my supergoal. Glad that I found this resource and speacial Thank You to Roni Das - Great Job!
The material has been designed with a lot of effort and dedication. It has covered vast range of topic with sufficient content and diagrams wherever required. It complements well with other system design materials.
