Course Description

Enhance Your Generative AI Expertise with Retrieval Augmented Generation (RAG) and Knowledge Graph


Retrieval-augmented generation (RAG) is a powerful approach for utilizing generative AI to access information beyond the pre-trained data of Large Language Models (LLMs) while avoiding over-reliance on these models for factual content. The effectiveness of RAG hinges on the ability to quickly identify and provide the most relevant context to the LLM. Knowledge Graphs transforms RAG systems with improved performance, accuracy, traceability, and completeness.

The RAG with Knowledge Graph, also known as GraphRAG, is an effective way to improve the capability of Generative AI. Take your AI skills to the next level with this ultimate course, designed to help you unlock the potential of LLMs by leveraging Knowledge Graphs and RAG systems.


In this course, you will learn:

  • Introduction to RAG Systems: Discover why Retrieval Augmented Generation is a groundbreaking tool for enhancing AI.

  • Foundations of Knowledge Graphs: Grasp the basics of knowledge graphs, including their structure and data relationships. Understand how these graphs enhance data modeling for RAG.

  • Implementing GraphRAG from Scratch: Build a fully operational RAG system with knowledge graphs. Use LLMs to extract and organize information.

  • Building Knowledge From Multiple Data Sources: Learn to integrate knowledge graphs with unstructured and structured data sources.

  • Querying Knowledge Graphs: Gain practical experience with leading tools and techniques.


Technology Highlights:

  • Spring AI: A new technology from famous Java Spring to help engineers work easily with various Generative AI and Large Language Models

  • Open AI: The innovative Generative AI that everyone loves. A groundbreaking tool for Large Language Models and AI.

  • Neo4J: Graph database and Vector store that integrates easily with Spring AI to form RAG and Knowledge Graph

  • Temporal: A workflow orchestrator platform to help engineers build a reliable GrahRAG pipeline.


Mastering advanced AI techniques offers a significant edge in today's fast-paced, data-driven world. This course provides actionable insights to enhance your career or innovate in your field.

Instructor Details

Timotius P

Timotius came from small Indonesian city but now working on it's capital : Jakarta. He's been in software engineering job for years. His first job was in the large consumer finance in Indonesia. Then he took a role as Engineering Manager on Indonesian unicorn. Few moments after, he moved back to another large Indonesian consumer finance and take a role on Engineering & Architect Head.

Taking the role as Head, he get more time to coach his team members about software engineering practice.

With more than 5 years experience as Java developer, and for the last few years handle enterprise complexity as Engineering Manager & Enterprise Architect, he will be glad to deliver high quality courses containing information of various technologies and software architecture design skills that he has acquired through his professional experience.

His goal is to deliver courses that not only good in theory, but also applicable in real-life use cases. His courses give the concept, and the hand-coding experience. He will  also provide various resources, including source code to hands-on coding.

i'm half way of the course on RAG via Spring Boot AI and the course touched nothing of it, instead it explains how to install VS CODE on Windows (poor choice for java developers) and explains basics of writing prompts. Come on, someone who needs details on RAG can skip very basic explanation on all these, because otherwise he wouldn't know what is RAG and what is Spring

By Ivan Ramos on 10/29/2025

Awesome content! Really well explained and logic order of chapters seem optimal to learn from basics to advanced concepts

good for start AI journey

very helpful to start AI journey

Quite good content. I've been took this instructor's course several times and it goes beyond the basic. This course sound is also better (I think the instructor uses some AI to generate the voice, but it is better. The english is well understood). The Spring AI course itself is good,goes beyond the official documentation give.

By Lovedeep on 12/26/2024

Course content is good, but the instructor instead of recording this in his voice, he has made this with some AI. All the content feels creepy, robotic voice. I would like to suggest Timotius to please make this in the original way. Learner connect better to real person voice than machine generated.

Excellent explanation. The steps are easy to follow, and the knowledge (theory) is well-explained before coding. This really helps me know new area in Java Spring and Generative AI

By JihanSatoru on 11/29/2024

I like it, thanks for such excellent course

By Pixel Training on 11/21/2024

I think this is the only course that teaches advanced Spring AI. Some other courses basically translate Spring documentation to video format, but this course goes beyond that. I think this one is good, since it more focus on narrow feature, but goes deep.
