🥇 Top Rated Plus | 41+ Jobs Completed | 3,200+ Hours | 100% Job Success I'm Syed Umair, a senior mobile app developer with 9+ years of experience building and hardening production apps in Flutter and React Native. Clients come to me for two things: building solid mobile apps from scratch, and honestly telling them what's broken, unfinished, or risky in apps they already have.

WHAT I DO: 📱 Mobile App Development Custom Flutter & React Native apps for iOS and Android, from idea to App Store launch. Clean architecture, maintainable code, real production readiness (not just "it works on my machine"). 🔍 Code & Production-Readiness Audits I review existing Flutter/React Native + Laravel/Node/Firebase codebases and give you a clear, prioritized verdict: what's a launch blocker, what's safe for beta, what's just technical debt. Non-technical founders especially value this, I explain everything in plain language. 🔗 Backend & Integrations Laravel, Node.js, and Firebase backends. Stripe payment integration (subscriptions, auto-charges, webhooks, refund/failure handling), Google Maps/Navigation SDKs, real-time features (WebSockets/Firebase). 🚀 App Store & Launch Support In-app purchase setup, App Store/Play Store submission, and post-launch troubleshooting. WHY CLIENTS WORK WITH ME: ✔ Direct, honest technical judgment, I tell you what's actually true, not what's easiest to hear ✔ Clear communication tailored for both technical and non-technical founders ✔ Strong track record auditing and hardening apps others built ✔ Full-cycle: architecture review → development → integration → launch TOOLS & TECH: Frontend: Flutter, React Native, Kotlin (native Android) Backend: Laravel, Node.js, Firebase Payments: Stripe (webhooks, subscriptions, auto-billing) Other: Google Maps/Navigation SDK, TestFlight, App Store/Play Store submission Have an app that needs to get built right, or an existing app you're not sure is really production-ready?
