Your app works locally… but crashes after deployment? 😩
One of the most common mistakes I see is forgetting that local and production environments are different.
Before deploying, always check:
✅ Environment variables are correctly configured
✅ Production database credentials are set
✅ API URLs point to the right environment
✅ CORS settings allow your frontend
✅ Build errors are resolved
✅ Authentication works in production
My rule: Never assume that because it works on localhost, it's ready for production.

Most honey brands hide how much a jar changes harvest to harvest. I built HIVE INDEX to document it instead: specimen numbers, harvest dates, tasting notes logged like lab evidence, not marketing copy.
Case study's up.
Option 2 closes on a four-up room grid while Option 1 keeps one full-width room per section — the grid suits browsing a catalogue, the stacked version suits selling a single look.
