🥇 Top Rated Plus | 45+ Total Jobs | 4,000+ 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. I don't sugarcoat audits, if something isn't production-ready, I'll say so clearly and back it up with evidence. WHAT I DO: 📱 Mobile App Development Custom Flutter & React Native app development for iOS and Android from idea to App Store launch. Clean architecture, maintainable code, and real production readiness, not just "it works on my machine." Native Android development in Kotlin where needed. 🔍 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. This includes code review, security audits, legacy code refactoring, and technical due diligence for founders considering a codebase takeover. Non-technical founders especially value this, I explain everything in plain language. 🔗 Backend & Integrations Laravel API development, Node.js backend development, and Firebase (Authentication, Firestore, Realtime Database, Cloud Functions). Stripe payment gateway integration (subscriptions, auto-charges, webhooks, refund/failure handling), Google Maps & Navigation SDK integration, push notifications, and real-time features via WebSockets/Firebase. ⚡ Rapid MVP & AI-Assisted / Low-Code Builds Need something live fast? I use modern AI-assisted tooling to go from idea to deployed in days, not months: - Lovable.dev – AI-powered full-stack app generation, extended with custom logic, integrations, and production hardening - Replit – Rapid prototyping and cloud-hosted MVP builds - Base44 – Internal tools and ops dashboards built in hours, not weeks - Bolt.new / v0.dev – AI-assisted frontend & UI generation for faster design-to-code delivery - Cursor / Claude Code – AI-assisted development for 3-10x faster coding, debugging, and codebase audits on web & mobile Whether you need a traditional, carefully architected build or a blazing-fast MVP, I speak both languages fluently and I'm honest about which approach actually fits your project's stage and goals. 🚀 App Store & Launch Support In-app purchase setup, App Store Optimization, TestFlight beta testing, and App Store/Play Store submission, including handling approval issues so your app doesn't get stuck in review. 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, refactoring, and hardening apps built by other developers ✔ Full-cycle: architecture review → development → integration → launch
