🚀Building with Bolt: How I Created Smile2Earn

🧠 What I Built

I constructed Smile2Earn, a web application that employs AI-powered smile recognition to reward users with virtual money in the form of SMILE Coins whenever they smile. It was our aim to create something significant and happy — a system that converts positivity into tangible value.

• Users authenticate with Supabase
• Smile recognition is performed in-browser with TensorFlow\.js
• Users receive SMILE Coins (100 SMILE = ₹1)
• A wallet keeps coins earned
• Withdrawal system (through UPI or bank) is developed but on hold
• Revenue is on a plan through ad monetization

⚙️ Technologies Utilized

• Bolt.AI – for boilerplate generation, bug fixes, and rapid logic writing
• TypeScript + Tailwind CSS – for responsive and clean UI
• TensorFlow\.js – for smile detection in real-time
• Supabase – for authentication and database storage
• Vite – rapid build setup
• Secure Storage – for session data and tokens

⚒️ Challenges I Overcame

1. Conflicts of Dependencies

• Dependencies such as @nativescript/firebase versions were outdated or non-existent
• Bolt assisted in producing alternative code with improved support

1. Smile Detection Logic

• Timing TensorFlow's smile detection to prevent false positives
• Detecting in a privacy-safe and light manner for real-time application

1. Authentication Flow

• Merging Supabase's auth into my own custom frontend logic
  • Bolt assisted in creating working login, signup, and logout handlers

⚡ How Bolt AI Altered My Workflow

• Time saved correcting errors, maintaining code versions, and sorting out npm problems
• Created fully functional Supabase integration
• Allowed me to test concepts quicker without being caught in technical dead-ends
• Played the role of coding mentor when I encountered roadblocks

🎯 Final Thoughts

This wasn't just about code — it was about creating something joyful.
Thanks to Bolt.AI, I wrote an app that pays individuals for smiling — and that, to my mind, is a huge success.
