I build Flutter apps that real people use — including government safety apps live on the Play Store with over 1 million downloads. Recently I've specialized in AI-powered apps: ChatGPT-style assistants with streaming responses, image understanding (vision), and voice input using OpenAI, Gemini, and Claude APIs. Just this month, I took two client apps from broken builds to LIVE on both the Google Play Store and Apple App Store — handling everything from bug fixes and Firebase configuration to Apple review rejections and final approval. Other recent work includes an AI chat app with real-time streaming (SSE), an AI health companion that reads glucometer photos and analyzes meal images, and a complete arena booking & finance system on Firebase. My background also includes native Android (Kotlin/Java) from building public safety and surveillance systems for the Punjab Safe Cities Authority — mission-critical apps where crashes are not an option. What I can help you with: AI integration — ChatGPT/Gemini/Claude assistants with streaming, vision & voice Flutter app development (Android, iOS, Web) App deployment to Google Play Store and App Store — including fixing rejections Firebase integration (Authentication, Firestore, Push Notifications) Bug fixing, performance optimization, and app stabilization REST API integration and backend connectivity Real-time features and live data handling Clean, responsive UI for all screen sizes MVP development for startups (Flutter or FlutterFlow) Technical expertise: Flutter & Dart AI APIs — OpenAI (GPT), Google Gemini, Anthropic (Claude): streaming (SSE), vision, secure key handling Kotlin & Java (Native Android) Firebase (Auth, Firestore, FCM) REST APIs and JSON integration State Management (Provider, GetX, BLoC) SQLite and local storage Google Maps integration Why clients work with me: Proven at scale — my apps serve over a million users Production-quality code, not quick hacks Reliable communication and clear updates I finish what I start — including the painful store-approval process Whether you need AI features in your existing app, a full new app, bug fixes, or help getting your app published, I deliver clean, stable solutions ready for real users.

Over the last 15 years, I have been a passionate Flutter Developer and Mobile App Developer. I know how to tame development chaos and deliver projects on time. How to coordinate developers and clients. What is important and what is a waste of time and money. My experience: - 15+ years in software development. - Last 6 years main focus: Flutter app developer. Before switching to Flutter Stack, I worked as a native mobile app developer (iOS, Android) and a React Native developer. Мy experience also includes low-level things like BLE, Image processing, and ARKit. I am not scared of diving into native development if required, and writing some Swift, Kotlin, Java, or even Objective-C. I started my career when the first smartphones came out, when iOS Development and Android app development were hell. Besides being a Flutter Developer, I am a Full Stack Developer too. This experience helps when you need to integrate your beautiful Flutter App with a complex backend and implement sophisticated flows for your processes. I can implement push notification with Flutter Firebase Cloud Messaging, payment flow with Stripe, or RevenueCat. Email with SendGrid, Mailgun etc. Real-time chats with Flutter Firebase Cloud Storage, or with a custom ASP.NET solution that features Redis and PostgreSQL. As a Full Stack Developer, I can also implement support of real-time geolocation features in your app. For backend, I prefer ASP.NET Core with C#. But I have experience with Node.js, Go, and PHP, Laravel. And if you really need that, I can even implement a backend on WordPress. Firabase is also an option, but there are caveats that we need to discuss before you choose this technology. That I am a Flutter Developer doesn't mean that I can't do a nice web page for the app on Next.js, or an admin dashboard on React. Almost every mobile app that is more complicated than a to-do list requires some kind of backend and admin dashboard for it. As a Flutter Developer, I published a lot of mobile apps in the App Store and the Play Store. During the publishing process, you need a lot of supporting things, like a website with a privacy policy and a contact us form. I can help with this, too, and do them using React, Next.js, or WordPress. One of my unique points is that I combine Flutter Developer and Mobile App Development experience with Computer Vision specialist skills. This allows me to integrate your latest models directly into the mobile app, avoiding common pitfalls. And make them robust and perform well even on a slow smartphone. Last few years, I worked as a Full Stack Developer and Flutter Developer for Allimb AI startup, and we successfully released the app in production. And now hundreds of patients use it every day. My responsibilities were mobile app development for a Flutter App and implement an ASP.NET Core backend. And supervise the work of AI experts who implemented exercise-specific models on Python and Dart. I helped to bridge a gap between Python algorithms and scripts used to train CV models, and their adoption as Dart code into a Flutter App. For Web Development, I prefer to use TypeScript over JavaScript, React over Angular, and Tailwind over writing CSS. But if needed, I can go vanilla JavaScript, CSS, and HTML. In general, developers often promise a lot, but deliver a little. If you are tired of false promises, developers that require a lot of hand-holding, and failed estimates. I am your new Flutter Developer. I will never promise what I can't deliver. You will always know what you can count on. I love Flutter and love to be a Flutter Developer. It started as mobile app development, but now I also deliver desktop apps, web applications, and robust backends. I stopped working with FlutterFlow; with AI power, it's easier to use Flutter directly. With Love, Your Flutter Developer
