Learn RAG, LangChain, Vector DB’s, with this project, FULL COURSE

Building this project taught me everything I needed to know about LLM’s, RAG (Retrieval Augmented Generation), LangChain, LangGraph, Vector databases, similarity search (FAISS) to secure a $74,000 AI Engineer job offer here in Sweden.

I’m a self-taught programmer with strong interest in AI and LLM’s.

This video is for anyone looking to learn these topics and become an AI Engineer yourself. In this video we will develop CondoGPT, a real estate AI that interacts with an SQL database, Google Maps API, Google Directions API, data visualization with Chart.js and report generation with ReportLab.

Many of you are probably looking for LangChain and LLM projects to add to your portfolio. Use this project to get open-source experience with AI technologies which solve real-world business issues

The full code is available on GitHub and has some issues for anyone interested in contributing. You can work on these to be listed as a contributor. If you spot any areas for improvement, feel free to submit your own issues and solutions—open-source contributions like this are a fantastic way to gain experience and showcase your skills on your resume.
