Frontend vs Backend vs Database: How to Build Real Apps in 2025 (Full Architecture Walkthrough)

AI can generate entire apps now… but here’s the catch:

If you don’t understand the structure underneath what you just built, you’re one bug away from being completely stuck.

This video breaks down the **5 layers every modern app uses**, whether it’s Instagram, ChatGPT, or something you vibe-coded last night. If you want to level up from “demo” to “production-ready,” this is *the* mental model you need.

### **What we cover:**
- The **5 core layers** of every software product
- What each layer *actually* does
- How to avoid common architecture mistakes
- Why AI didn’t replace system design
- Hot takes on frontend obsession, database design pitfalls, vendor lock-in, and auth
- How to debug apps faster by knowing where to look
- A 10x developer exercise to apply after the video
