Hey Product Hunt! I'm thrilled to share Artistic Walls — my first production app and a wild learning journey! Why I Built This: I wanted to learn serverless architecture and edge computing by building something real. What started as a simple wallpaper app became a deep dive into: - Firebase auth WITHOUT Admin SDK (manual JWT validation) - Cloudflare Workers + D1 + R2 (full serverless stack) - Google Play billing server-side validation - Building backend in JavaScript (I'm a Flutter dev!) The AI-Assisted Journey: I used AI editors (Cursor, Claude) to navigate unfamiliar JavaScript, especially for crypto logic. But every line was reviewed and tested — AI suggested, I architected. What Makes It Different: Unlike traditional wallpaper apps hosted on AWS/GCP, Artistic Walls runs on Cloudflare's edge network. This means: Instant loading from 300+ cities worldwide No cold starts (serverless Workers) Smart caching reduces costs Premium content with subscriptions 🧪 14 Days of Testing: Spent two weeks with 12+ testers finding edge cases. Real users taught me more than any tutorial. Current Challenge: Optimizing database queries to keep Cloudflare costs low while maintaining performance. Any advice from the PH community would be amazing! Would love your feedback on: - UI/UX improvements - Feature requests - Backend architecture suggestions - Serverless optimization tips Thanks for checking it out! If you try it, I'd love to hear your thoughts! https://play.google.com/store/ap...
