Most mobile projects fail not because of bad ideas, but because of bad developers. Wrong tech choices, missed deadlines, and half-finished apps are the norm on Upwork. I am Talha, a Flutter and NestJS developer with 5 years of production experience. I have shipped apps that crossed 10,000+ downloads I have shipped apps that crossed 10,000+ downloads and managed PostgreSQL databases with millions of records in production. I have also built 5 products solo that are live on the App Store, Play Store, and Web right now. I also publish open source Flutter packages used by developers worldwide, which means I understand Flutter deeply enough to contribute back to it, not just use it. What this means for you: You get one developer who builds the app and the backend. No coordination between multiple freelancers. No excuses. Just a complete product delivered and deployed. I have built social apps, AI-powered tools, health and nutrition trackers, real-time communication apps, e-commerce platforms, and educational tools. If your idea fits mobile or web, I have likely built something close to it already. Strong English. Clear communication. I ask the right questions before writing a single line of code.

I am expert in creating cross-platform iOS/Android applications in Flutter, Xamarin Android, Xamarin iOS and Native Code. I have a strong knowledge of basics, such as common design patterns (MVC, Clean code, etc.), programming languages (Dart, Java, C#, PHP, JavaScript) and standard iOS frameworks (UIKit, MapKit, SpriteKit, Apple Pay, Apple Signin etc.), I also have a great experience in wide number of third-party SDKs: Google Firebase, Facebook, PayPal, Stripe, Google Maps, ad networks, Parse Server etc. Main focus on Back-end development. The work I provide is of the highest quality, fully responsive, and tested in a wide range of devices. I take care to ensure each project is well-architected, well-documented and easily maintainable so you can enhance an app, as your company grows. I'm also much familiar with implementing in-app payments, like In-App Purchases and subscriptions, Apple Pay, Google Pay, PayPal and Stripe SDKs (both client side and server side). My experience with payment systems allows me, to help with choosing the optimal ways for monetization, which leads to increase a company's revenue. I can guide through Apple app review process, to make it smooth and avoid any rejections. I put my heart into the projects to make professionally functional and of great quality with responsiveness. I design and think very carefully about my code before starting coding. I worked on several projects building backend servers on PHP and C#, building Rest API, complex algorithms and other server features. Best Regards: -HAMMAD ALI...

AI-powered mobile apps, native on iOS and Android from one codebase. Most businesses don't want to pay to build the same app twice. And the ones adding AI don't want a feature that demos well but falls apart the moment real users touch it. I handle both. One codebase runs native on both platforms, looks right on each, and costs a fraction of building them separately. When there's AI inside, whether that's a copilot, a chatbot, or a RAG assistant working from your own data, I also do the part most developers skip. Evaluations, guardrails, and cost control, so it stays accurate once real traffic arrives. I've shipped 95+ projects: booking apps, marketplaces, fintech tools, social platforms, and AI apps. And I don't just hand over a front end. Most of my work comes with the full backend and an admin panel, so your team can actually run the app after launch instead of coming back to a developer for every small change. What I build: → AI-powered apps. Copilots, chatbots, and RAG assistants grounded in your data, with citations and controls to cut hallucination. Built into a real product, not a demo. → Booking and on-demand apps. Scheduling, real-time availability, and Stripe payments cleared before anyone shows up. → Marketplaces and deals apps. Browse, subscribe, and redeem, with checks like OTP verification so offers can't be gamed on either side. → Fintech and business tools. Wallets, dashboards, and apps that move money, built with the security that side needs. → The full package. Mobile or web front, backend in Laravel or Node.js, and an admin portal so your team updates content without waiting on a new release. A few things I've shipped: → An AI travel planner that turns one plain-language prompt into a full, editable itinerary, built with OpenAI, Flutter, and Laravel. → An on-demand massage app that books a licensed therapist to a home or hotel in a few taps and takes payment up front. → A 2-for-1 restaurant deals app where every redemption clears an OTP check, with a Laravel portal where restaurants confirm and track redemptions. How I work: You deal with the person writing the code, not a manager passing messages along. Tell me what you're building and I'll come back with a real stack, scope, and timeline, usually within a few hours.
