Code Follow-up: https://youtu.be/ZREt9MAozho This is how I think through designing a full stack AI Agent System, with all key concepts you need -- Vector Database, Retrieval-Augmented Generation (RAG), Semantic Search & Policy Checks, Function Calling and more. The use case I picked is to manage e-Commerce customer support. You can learn it even if you don't come from a technical background. You can build anything. You can learn anything. 💪 Launch Full-Stack App Template: https://github.com/ShenSeanChen/launch-mvp-stripe-nextjs-supabase My AI Agent Startup AutoManus.io - an AI Sales Leads Manager for Businesses Selling Physical Products ☕️ Buy me a coffee: https://buy.stripe.com/5kA176bA895ggog4gh - X: https://x.com/ShenSeanChen - Discord: https://discord.gg/TKKPzZheua - LinkedIn: https://linkedin.com/in/shen-sean-chen - Github Link: https://github.com/ShenSeanChen - Instagram: https://www.instagram.com/sean_tech_stories Sub Count when launched: 5615 Top Github Repos - LaunchMVP NextJS,Supabase,Stripe (797 stars): https://github.com/ShenSeanChen/launch-mvp-stripe-nextjs-supabase - ReactNextJSTips (45 stars): https://github.com/ShenSeanChen/yt-react-nextjs-tips - SupabaseTipsKanban (22 stars): https://github.com/ShenSeanChen/yt-supabase-tips-kanban - KimiK2Claude (21 stars): https://github.com/ShenSeanChen/yt-kimi-k2-claude - AuthSupabaseGoogle: https://github.com/ShenSeanChen/yt-auth-supabase-google - FastapiGCPPro: https://github.com/ShenSeanChen/yt-fastapi-gcp-pro - SupabaseHero: https://github.com/ShenSeanChen/yt-supabase-hero - LaunchAnApp: https://github.com/ShenSeanChen/yt-launch-an-app You Can Build Anything Playlist (Full-Stack Dev Without CS Degrees) - Core7: 95% React/NextJS Use Cases https://www.youtube.com/watch?v=vZzFlAjz4rA&list=PLE9hy4A7ZTmpGq7GHf5tgGFWh2277AeDR&index=16 - Core6: 95% Supabase Use Cases https://www.youtube.com/watch?v=Pnoq2tIif3s&list=PLE9hy4A7ZTmpGq7GHf5tgGFWh2277AeDR&index=15 - Core5: StripeNextJSSupabase https://www.youtube.com/watch?v=ad1BxZufer8&list=PLE9hy4A7ZTmpGq7GHf5tgGFWh2277AeDR&index=8 - Core4: AuthSupabaseGoogle https://www.youtube.com/watch?v=AZAU3ClAWWE&list=PLE9hy4A7ZTmpGq7GHf5tgGFWh2277AeDR&index=6 - Core3: FastapiGCPPro https://www.youtube.com/watch?v=u3sfqpzzo-U&list=PLE9hy4A7ZTmpGq7GHf5tgGFWh2277AeDR&index=5 - Core2: SupabaseHero https://www.youtube.com/watch?v=V0kmgkyPsVQ&list=PLE9hy4A7ZTmpGq7GHf5tgGFWh2277AeDR&index=4 - Core1: LaunchAnApp https://www.youtube.com/watch?v=iQ2izvGG4tQ&list=PLE9hy4A7ZTmpGq7GHf5tgGFWh2277AeDR&index=3 - Launch WhereToMeet w/ GoogleMaps, Calendar, Supabase, Cursor: https://www.youtube.com/watch?v=5xMjX1QxGUY&list=PLE9hy4A7ZTmpGq7GHf5tgGFWh2277AeDR&index=2 - Launch EncourageMe w/ Cursor, Supabase, Vercel https://www.youtube.com/watch?v=hnvL4xa2DHA&list=PLE9hy4A7ZTmpGq7GHf5tgGFWh2277AeDR Timeline 00:00 Intro 00:23 Problem to Solve Today 00:59 Goals 02:13 Rules of the Scope 03:39 Backend & Database 04:13 Vector Database VS Relational DB 04:38 What's a Vector Database 05:31 Sketch the AI Agent System Design 05:53 User Auth Gateway 06:32 CRUD with Relational DB 06:49 How Would AI Agents Interact with User Chats 07:08 Introducing Router Agent 07:38 Q&A AI Agent (The Brain/CEO) 08:36 When to Loop in Humans? 09:20 How the Router Agent Proceeds 09:33 Planner Agent 09:58 What is Functional Calling? 10:15 Tools & APIs 11:24 Should We Use AI Agents or Deterministic Workflows 12:28 Retrieval-Augmented Generation (RAG) + Vector Database 14:39 What Happens after RAG 15:45 The Q&A Agent 17:02 AI Agent System Design Overview 17:10 Observability, Metrics, Evals 17:49 CRM Integration 18:29 Final Overview
