An LLM is an incredibly powerful brain that knows everything about humanity and nothing about you or the software you run. This video walks through the four buzzwords that turn that raw brain into a system you can trust: agent harness, loop engineering, LLM Ops, and eval. No jargon, step by step, technical or not. You can build anything. You can learn anything. 💪 Timeline 0:00 Intro: the 4 AI agent buzzwords 0:42 What an AI agent run actually is 1:52 The memory system: procedural, semantic, episodic 3:37 What "harness" really means (the horse) 5:07 Storing and updating memory (databases, skills, summarizer agent) 8:28 Retrieval: RAG, SQL vs semantic search 10:00 Tool calling and why agents loop 10:52 Loop engineering and end-loop guardrails 13:21 A Claude Code hooks example 14:18 Eval and LLM Ops: why you need them 15:55 Tracing every run (Langfuse, LangSmith) 16:43 Evaluation: LLM as a judge 17:20 Diagnosing what broke 18:16 The gate: ship the fix or fix the bug 18:57 Zoom out: the full system 19:53 Wrap up Launch Full-Stack App Template: https://github.com/ShenSeanChen/launch-mvp-stripe-nextjs-supabase My AI Agent Startup AutoManus.io is an AI sales lead manager for made-to-order product sales.

In this full stack development course, you will learn how to create an application using MongoDb for the database, Java and Spring Boot for the backend, and React for the frontend. You will learn to develop a movie review application that will feature a separation of concerns between the client code and the server code. By implementing this loosely coupled architecture, these two parts (implemented using different technologies) can evolve in parallel and independently from one another. ✏️ Farhan Hasin Chowdhury teaches the backend section. ✏️ Gavin Lon teaches the frontend section. @GavinLon 💻 Backend Code: https://github.com/fhsinchy/movieist 💻 Frontend Code: https://github.com/GavinLonDigital/movie-gold-v1 🔗 Spring Initializr - https://start.spring.io/ 🔗 JDK Download Page: https://www.oracle.com/java/technologies/downloads/ 🔗 IntelliJ IDEA Download Page: https://www.jetbrains.com/idea/download/ 🔗 Postman Download Page: https://www.postman.com/downloads/ 🏗 MongoDB provided a grant to make this course possible. ❤️ Try interactive Full Stack courses we love, right in your browser: https://scrimba.com/freeCodeCamp-Fullstack (Made possible by a grant from our friends at Scrimba) ⭐️ Contents ⭐️ ⌨️ (0:00:00) Course Introduction ⌨️ (0:01:48) JDK and IntelliJ IDEA Installation ⌨️ (0:06:13) MongoDB Atlas ⌨️ (0:20:35) Project Initialization ⌨️ (0:27:03) Project Structure ⌨️ (0:29:13) Running The Project ⌨️ (0:32:41) Writing The First Endpoint ⌨️ (0:35:33) Database Configuration ⌨️ (0:38:49) Installing Additional Dependencies ⌨️ (0:44:48) Setting Up Environment Variables ⌨️ (0:47:20) Movies and Reviews Endpoints ⌨️ (1:31:46) Testing ⌨️ (1:35:42) Backend Conclusion ⌨️ (1:36:45) Frontend Introduction ⌨️ (1:38:32) Create the React Project ⌨️ (1:43:49) Applying Bootstrap to our React application ⌨️ (1:52:47) Implementing the Use State and Use Effect Hooks ⌨️ (1:58:04) Create Home and Hero Component ⌨️ (2:06:56) Style the Carousel ⌨️ (2:15:21) Create Header Component (Navigation) ⌨️ (2:21:55) Create Trailer Component with react-player ⌨️ (2:28:46) Create Movie Reviews Functionality ⌨️ (2:34:43) Add and Get Reviews with HTTP Requests ⌨️ (2:40:33) Course Wrap Up 🎉 Thanks to our Champion and Sponsor supporters: 👾 Nattira Maneerat 👾 Heather Wcislo 👾 Serhiy Kalinets 👾 Erdeniz Unvan 👾 Justin Hual 👾 Agustín Kussrow 👾 Otis Morgan -- Learn to code for free and get a developer job: https://www.freecodecamp.org Read hundreds of articles on programming: https://freecodecamp.org/news
