    AI & LLM Engineering

    Learn how AI systems work inside, then build ones you can trust in production: the maths, machine learning, deep learning, transformers, RAG, harnesses, agents, evals, fine-tuning, MLOps and security. Every part ends with two projects you build yourself. Code in Python, NumPy and PyTorch, with Go where it fits.
