👋 Hey Product Hunt! I'm Umam, and I built this in 7 days. **The context:** I'm a Go developer in Indonesia with 2 kids and 6 months runway. I researched 20 micro-SaaS ideas and QR Code API had the best validation signals—competitors charging $5-30/mo with proven demand. **The challenge:** Ship fast to validate demand OR spend weeks building features nobody asked for. I chose speed. **What I learned:** - CORS in distributed systems is HARD (spent 4 hours debugging duplicate headers) - AWS free tier is incredibly generous (1M Lambda requests/month forever) - Table-driven tests > mocking Lambda locally - Validation > perfection **Current tech:** - Go + AWS Lambda (stateless) - CloudFlare Workers (custom domain proxy) - 50-150ms response times - $0.50/month total cost **The bet:** If 10+ people sign up for launch notifications, I'll add SVG/PDF/logos and launch paid tiers. If not, I pivot to my next validated idea (Markdown→PDF API). **Try it free:** https://healnify.com Ask me anything about the tech stack, AWS costs, or why I'm building in public with limited runway!
