LLM Engineering Prompting, RAG, Fine– Tuning, and RLHF

What you'll learn

Design advanced prompts—zero-shot, few-shot, and chain-of-thought reasoning—that reliably produce high-quality, structured outputs at scale.
Architect and build complete RAG systems—covering ingestion, retrieval, and synthesis—then evaluate them rigorously for accuracy and grounding.
Fine-tune base models into specialized assistants using parameter-efficient methods like LoRA, QLoRA, rsLoRA, and LoRA-FA.
Align LLM behavior to human preferences using the full RLHF workflow and algorithms including PPO, DPO, and GRPO.
Combine prompting, retrieval, fine-tuning, and alignment into an end-to-end, production-ready LLM system.

Requirements

Understanding of Transformers & LLMs: Familiarity with neural networks, attention, and how LLMs are trained and generate text (Course 1 or equivalent knowledge).
Intermediate Python: Comfort reading and writing functions, loops, and basic data structures (code is explained step-by-step, but you should be comfortable reading Python).
Basic ML Intuition: Comfort with vectors, embeddings, and core training concepts like loss and gradients (all key ideas are refreshed intuitively throughout the course).

Description

Move beyond calling models to engineering them—master prompting, retrieval-augmented generation, parameter-efficient fine-tuning, and preference alignment to build production-grade LLM systems.
Agentic AI Mastery: Your 3-Stage Complete Learning Path
- Course 1: Large Language Models: From Foundations to Transformers
-Course 2: LLM Engineering: Prompting, RAG, Fine-Tuning, and RLHF
- Course 3: Agentic AI Engineering: Multimodal, MLOps & Agents
New to the series? Start with Course 1 to build your core baseline in deep learning, NLP, embedding spaces, vector search, transformer architectures, decoding methods, and LLMs.
Already comfortable with these foundations? You are in the right place. This course turns that theoretical foundation into practical engineering skills. Upon completing this course, you will be fully prepared for Course 3: Agentic AI Engineering: Multimodal, MLOps & Agents.
Why This Course
Most AI courses stop at "here's how to call an API", leaving you stuck when outputs are unreliable, knowledge is outdated, or a general-purpose model doesn't fit your domain. This course takes a different path.
We bridge the gap between knowing how models work and building systems that work in production. You'll master the four techniques that separate AI engineers from API users, prompt engineering, RAG, supervised fine-tuning, and alignment, working ground-up from core principles so your skills stay relevant as tools and frameworks evolve.
Course Modules
Module 1: Large Language Models (Review from Course 1)
Refresh and solidify the LLM foundations that everything else builds on. This module revisits how modern LLMs generate text—scaling laws, pre-training, SFT, and preference alignment—and takes you hands-on with decoding strategies and hallucination inspection, ensuring you're ready to engineer these models rather than just use them.
Module 2: Prompt Engineering
Master the craft of communicating with LLMs. Move from prompting fundamentals through proven engineering techniques to advanced strategies, learning to design prompts that consistently produce high-quality, reliable outputs across any application.
Module 3: Retrieval-Augmented Generation (RAG)
Build AI systems that combine LLMs with external knowledge. Walk through every stage of the RAG pipeline—ingestion, retrieval, and synthesis—then learn to rigorously evaluate your system, enabling responses that are accurate, up-to-date, and verifiable.
Module 4: Supervised Fine-Tuning (SFT)
Transform general-purpose models into specialized experts. Explore the limits of in-context learning, the fundamentals of fine-tuning, and efficient methods like LoRA and QLoRA (PEFT)—mastering datasets and training dynamics to adapt models to your domain without massive compute.
Module 5: Reinforcement Learning from Human Feedback (RLHF)
Shape model behavior to match human preferences. Understand why alignment matters, the reinforcement learning fundamentals behind it, and the full RLHF workflow—including PPO, DPO, and GRPO alignment algorithms.
