It’s time to stop being a code “bricklayer” and start being the architect. In this video, Martin Omander takes Google’s new agentic IDE, Antigravity, for a spin to build and deploy a full stack app to Cloud Run from scratch. Martin isn’t just doing autocomplete here.
Watch along as Martin demonstrates how to write a “spec sheet” for the AI, force it to use modern Node.js (no build steps!), and watch it autonomously debug a port mismatch during deployment without me touching a config file.
What we cover: The Career Shift: Why developer jobs are moving from typing syntax to managing workflows. Agentic Workflow: watching the AI plan, code, and browser test the app independently. The Stack: Why Cloud Run is a”cheat code” for deploying AI-generated containers (no server management required). Marin wants to hear your take. Let him know in the comments!

This is the prompt Martin used to build the app:
➡️ Act as a Senior Full Stack Developer. Build a web app called “GuestPass”.
**The Goal:** A WiFi QR Code generator that creates a printable “Guest Card” for visitors.
**The Stack:** 1. Backend: TypeScript with Express. 2. Frontend: A single `index.html` file served by Express from a `/public` folder. 3. Styling: Use Tailwind CSS via CDN.
**Core Requirements:** 1. User enters SSID and Password in a “Glassmorphism” styled form. 2. On submit, backend generates a QR code using the `qrcode` library. 3. CRITICAL: Do not save images to disk. Generate the QR code in memory (buffer) and return as a Base64 string. 4. Display the result in a printable card UI.
**Deployment (Modern Approach):**
* Use the `node:23` (or latest 22) Docker base image.
* DO NOT include a build step (tsc).
* Run the application directly using the `–experimental-strip-types` flag (e.g. `node –experimental-strip-types server.ts`). ⬅️
