⚠️ Problem I Faced in a Live App

In a production app, users complained about slow app startup, even though the UI was simple. The issue wasn’t design — it was unnecessary initialization at launch.

✅ How I Solved It

I optimized the startup flow by: • Deferring non-critical API calls • Lazy-loading heavy modules in Flutter • Initializing backend services (Firebase / Node.js) only when needed

🚀 Result

✔ Faster app launch ✔ Better first impression ✔ Improved user retention

💡 Lesson: First impressions in apps are defined in the first 3 seconds.
