Short break, long wait.</p> <p>That’s where the idea of MovieSync came from.</p> <h2> The Problem </h2> <p>Intermissions are limited, but there’s zero visibility on crowd levels. You just guess… and sometimes regret it.</p> <h2> The Idea </h2> <p>I built MovieSync, a real-time dashboard that shows how crowded different areas are inside a venue.<br> Simple color signals help you decide instantly:</p> <p>🟢 Low crowd<br> 🟠 Medium<br> 🔴 High congestion</p> <p>No guesswork. Just smarter decisions.</p> <h2> Tech Stack </h2> <ul> <li>React + Vite for a fast, lightweight frontend</li> <li>Vanilla CSS (no heavy UI libraries)</li> <li>Docker (multi-stage build)</li> <li>Nginx for serving the app</li> <li>Google Cloud Run for serverless deployment</li> <li>Antigravity to speed up development &amp; workflow</li> </ul> <h2> How I Built It </h2> <p>I focused on keeping things simple and clean.<br> Instead of using UI frameworks, I designed everything from scratch using glassmorphism styles, smooth transitions, and subtle animations.</p> <p>Since I didn’t have real sensors, I created a simulation that mimics real-time data (like WebSockets). The dashboard updates dynamically to reflect crowd density.</p> <h2> Deployment </h2> <p>Used Docker with a multi-stage build:</p> <ul> <li>Node → build optimized assets</li> <li>Nginx → serve the app on port 8080</li> </ul> <p>Deployed on Google Cloud Run for automatic scaling.</p> <h2> Where Antigravity Helped </h2> <p>Antigravity made a big difference by:</p> <ul> <li>Speeding up initial setup</li> <li>Making UI iterations faster</li> <li>Simplifying deployment flow</li> <li>Reducing overall complexity</li> </ul> <p>It helped me move faster from idea → working product.</p> <h2> Key Features </h2> <ul> <li>Real-time crowd dashboard</li> <li>Lightweight and responsive UI</li> <li>Dockerized production build</li> <li>Serverless deployment</li> <li>Built in public</li> </ul> <h2> What’s Next </h2> <ul> <li>Real IoT integration</li> <li>WebSocket backend</li> <li>Predictive crowd insights</li> <li>Mobile PWA version</li> <li>Multi-theatre support</li> </ul> <h2> Final Thought </h2> <p>This project showed me how quickly you can build something useful using the right tools. Building in public also made the journey more real and accountable.</p> <p><strong>What are you building right now? 🚀</strong></p> ai webdev programming antigravity
