Hi! I am Saurav.

I hold a 100% Job Success Score and Top Rated status on Upwork, backed by 10+ years building products — much of it outside this platform. I don't just write code. I think through your product, challenge weak assumptions early, and build things that hold up in the real world. My edge? I've shipped across enough domains — health, fintech, social, ecommerce, sports, media, edtech — to know what works before the first line of code. My sharpest focus right now is AI-powered mobile and web apps: products that don't just look smart, but genuinely behave that way.

No vague updates. No surprises at the finish line. I follow Agile Scrum, communicate proactively, and treat your deadline like it's mine — because my reputation depends on it. Need more firepower? When a project calls for it, I can scale up with a dedicated senior team — same standards, more bandwidth, with my oversight at every stage.

🥇 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. 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 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? Send me a message or click "Hire Me" and let's talk.

I build reliable, scalable, and launch-ready mobile apps for iOS and Android. My work covers the complete mobile product ecosystem: app development, backend APIs, admin dashboards, AI integrations, payments, subscriptions, cloud deployment, and App Store / Google Play launch support. I help startups, founders, and growing businesses build reliable, scalable, and launch-ready mobile applications for iOS and Android. My core expertise is mobile app development, but I do not approach mobile apps as isolated screens. A successful mobile product usually needs a strong backend, secure APIs, admin dashboard, payment system, scalable database, cloud infrastructure, third-party integrations, and a clear product roadmap. That is where I bring complete product development experience. As the CEO of CRYMZEE Networks Pvt. Ltd., I bring 10+ years of software development experience and lead a professional engineering and product team experienced in mobile apps, SaaS platforms, AI-powered applications, marketplaces, health-tech, fitness, logistics, e-commerce, business automation, and enterprise software solutions.

Weak architecture, unstable code, unclear workflows, and short-term development choices can become expensive later. My goal is to help clients build mobile apps that are not only functional for launch, but also ready for real users, business operations, future updates, and long-term growth. Whether you need a mobile app from scratch, an MVP, an AI-powered app, a SaaS mobile platform, a marketplace app, a business application, or improvements to an existing product, I can help you build it with the right technical foundation and a professional delivery process. Thanks!

I build production-ready Flutter MVPs and AI-powered mobile apps for founders, from idea to live on the App Store & Google Play. Not throwaway prototypes that break the week after launch. I'm Tasaddaq, a Top Rated Flutter developer with a Master's in AI and 6+ years building cross-platform iOS & Android apps. 35+ apps shipped, 100% Job Success, all 5-star reviews, and unlike most developers, I've built and launched my OWN AI products, not just client work: 🟢 Tertio — an AI wellness coach (Flutter · Supabase · Gemini), live on the Play Store 🟢 Dreambrush AI — an AI image-generation app (Flutter · OpenAI) 🟢 A live AI-powered relationship app, in production with real users So when you hire me, you're not paying someone to learn on your project — you're hiring a developer who has already taken AI apps from zero to launch. What I build for founders: ⚡ Full MVPs — idea → designed, built, and live on both stores 🤖 Real AI features — Gemini, OpenAI & LLM integration, not a chatbot bolted on ☁️ Production-grade backends from day one (Firebase / Supabase / Node), built to scale 🧩 Clean Riverpod architecture, so your next dev isn't rebuilding from scratch 🔧 Production rescues — I've restored login for 50,000+ locked-out users and fixed live apps with zero downtime Why founders keep working with me: I don't disappear mid-project. Every job I've taken on Upwork, I've finished, zero revision disputes. That's how I'm Top Rated with a 100% Job Success Score. You get a technical partner who owns your vision until it's live — not just a coder. Building an MVP or scaling an existing Flutter app? Message me your idea and I'll reply with the fastest realistic path to launch. FAQ Q — I just have an idea, no designs yet. Can you still build it? A — Yes. I'll scope the MVP, design it, build it, and ship it end-to-end. Q — I need AI in my app (chat, recommendations, image generation, automation)? A — That's my specialty — a Master's in AI plus live Gemini/OpenAI apps in production. Q — Can you deploy to both the App Store and Google Play? A — Yes — full production deployment on both, including store setup and review. Q — Will it scale past the MVP? A — Yes. Real backends + clean architecture, so v2 isn't a costly rewrite. Q — Do you handle backend and admin panels too? A — Yes — full-stack: Flutter front end + Firebase/Supabase/Node backends and admin panels.
