## What it is
A free hands-on course (source code plus 12 lessons) that teaches how to build an end-to-end production-ready LLM and RAG system by creating an 'LLM Twin' that writes in your style. It covers the full lifecycle including data crawling, ETL pipelines, streaming feature pipelines, fine-tuning, and deployment using LLMOps best practices.

## Use cases
- learn to build a production-ready RAG system
- how to fine-tune an LLM on my own writing style
- course on LLMOps and MLOps best practices
- build an end-to-end LLM system with microservices
- learn data pipelines for LLM training with vector databases
- deploy LLM applications on AWS with infrastructure as code
- hands-on lessons for streaming ETL with Bytewax and Qdrant

## When to choose
- you want a free, structured, project-based curriculum for production LLM engineering
- you learn best by building a complete system rather than isolated notebooks
- you want exposure to real MLOps tooling like experiment trackers, model registries, and prompt monitoring

## When to avoid
- you need a ready-to-use production product rather than educational code
- you want a quick tutorial instead of a 12-lesson course commitment
- you are looking for a lightweight library to drop into an existing project
