About AI Engineering: Zero to Production
studybydoing.in is a free, hands-on AI engineering course and curriculum that teaches by building. It covers the full path from Python and computer-science foundations to production AI systems — RAG, AI agents and tool use, evaluation, MLOps, the Anthropic API and Claude, AWS Bedrock/SageMaker, LangChain/LangGraph, multi-agent systems, fine-tuning and inference optimization — across 274 lessons, 9 case studies and 37 hands-on projects, each with worked exercises and runnable code.
What you'll find here
- A complete AI engineering path — LLM fundamentals, prompting & structured output, Retrieval-Augmented Generation (foundations → retrieval → re-ranking → scale → production), AI agents & tools (foundations → patterns → reliability → production), evaluation, and production hardening.
- CS foundations that AI engineering rests on — Python (beginner to CPython internals), data structures & algorithms, system design, and software testing.
- Platform & ecosystem — the Anthropic API and Claude, AWS Bedrock & SageMaker, LangChain/LangGraph, multi-agent orchestration, MCP and agent interoperability, MLOps/LLMOps, fine-tuning, local models, and inference/cost optimization.
- A free in-browser Python terminal (Playground) — run and test code with numpy, pandas, scipy and pydantic preloaded, no install required.
- Hands-on projects and capstones that assemble the pieces into complete systems.
Our approach
The course is built on one principle: you learn AI engineering by building it, not by reading about it. Every chapter pairs clear explanation with runnable code and graded exercises, from a first API call to a production-hardened agent. Content is written to be honest and practical — techniques are real and public, examples are labelled when they are representative, and code is meant to be run and adapted (see the Terms & disclaimer).
Who it's for
Software engineers, data scientists, and students who want to build production AI systems — whether you're starting from Python basics or already shipping and want depth on RAG, agents, evaluation, and operations.
Access & cost
Everything is free and public — no account, no paywall, no signup. The site is a static, independently-run learning resource. Questions or feedback: support@studybydoing.in.
