I help startups and SaaS teams build and scale production-ready web applications using React, Next.js, and Node.js. Whether you're launching an MVP, improving performance, or scaling an existing product, I take full ownership of the feature from architecture to deployment so it works reliably in production, not just in development. I’ve built dashboards, authentication systems, payment integrations, and complex backend workflows for long-term SaaS platforms. I’m comfortable working inside existing codebases, improving architecture, and shipping clean, maintainable solutions. Core stack: React.js, Next.js, TypeScript, Node.js, Express.js Supabase, MySQL, MongoDB, Firebase REST APIs, GraphQL, TanStack, React Query, JWT, OAuth, role-based auth Vercel, Google Cloud, serverless deployments I’m comfortable working inside existing codebases, refactoring messy systems, optimizing database queries, and improving backend performance. What I bring: • Full stack ownership (frontend + backend) • Scalable API and backend architecture • Secure authentication and payment integrations • Clean TypeScript-based code structure • Performance optimization and refactoring • Smooth deployments (Vercel, GCP, AWS, serverless) You won’t need to micromanage me. I communicate clearly, think in systems, and focus on building software that lasts.

I’m a Flutter & FlutterFlow Developer specializing in AI integrations, Firebase, APIs, and production-ready mobile applications. With 3+ years of experience, I help startups and businesses turn ideas, Figma designs, or existing apps into scalable iOS and Android products using Flutter, FlutterFlow, Firebase, REST APIs, and AI technologies such as OpenAI and Gemini. My focus is on building fast, reliable, user-friendly apps with clean architecture, strong backend integration, and a smooth development experience from MVP to production. **Core expertise includes:** • Flutter & FlutterFlow development • AI integrations — OpenAI & Gemini • Firebase (Auth, Firestore, Storage, Cloud Functions) • REST API & third-party integrations • Payments, notifications, maps & real-time features • App optimization, bug fixing & deployment I’ve worked on business, healthcare, social, booking, e-commerce, and AI-powered applications. If you have an idea, Figma design, or an existing app that needs to be built, improved, or scaled, I can help turn it into a reliable, production-ready product.

I build Flutter apps people actually depend on. The Courier App runs 6,000+ UK drivers on code I shipped, and Calcount has 1,000+ users in Australia. 100% Job Success, Top Rated, and I get apps through App Store review on the first try. 🚀 I go deepest on the parts most devs avoid; real-time, payments, hardware; here's the full kit: 📹 Video Calling: Agora, Zego, VideoSDK.live, Jitsi, WebRTC 📞 VoIP: SIP calling and real-time communication 📡 BLE: ESP32-WROOM-32D, Nordic nRF52840, Adafruit Bluefruit nRF52, Keil 💳 Payments: Stripe, In-App Purchases, RevenueCat ☁️ AWS: EC2, CloudFront, S3, Route53, SNS, SES, MediaConvert ⚡ Supabase: Edge Functions, Auth, Realtime, the full stack 🔥 Firebase: Cloud Functions, Cloud Console, Firestore, FCM, Analytics 🗺️ Maps: Google Maps, Mapbox, OpenStreetMap, live tracking, geofencing, navigation 🎬 Media: FFMPEG, HLS streaming, AWS MediaConvert 🤖 AI: OpenAI, Gemini, Claude, YouTube Transcript APIs 🔐 Auth: Email/Password, Phone OTP, Google, Apple Sign-In 💬 Realtime Chat: SocketIO, WebSockets, Google gRPC Protocol Buffers 🗄️ Backend: Node.js, NestJS, Laravel, Django, MongoDB, PostgreSQL 🔔 Notifications: OneSignal, Firebase Push Notifications 🔗 Deep Linking and Referral Systems 📊 Monitoring: Sentry, PostHog (used on every project) 🔄 CI/CD: GitHub Actions, Azure Pipelines 🏗️ Architecture: DDD, Clean Architecture, Repository Pattern, BLoC, Riverpod, Provider 🎨 Animations: Lottie, Custom Painters, complex UI 🛒 E-Commerce: WooCommerce, custom cart systems 📍 Location: Background services, geofencing, live tracking, on-map navigation Don't just take my word for it 💬 🇹🇷 Berk (Voltran, Turkey): "This kind of work ethic is not easy to find" 🇸🇬 John Alam, CEO Nautilus SIP (Singapore): "Shahzad is quite hard-working, he spends good time trying to find the solution and ensures he has tried all possible ways before giving up" 🇬🇧 Chris Hamilton, CEO The Courier App (UK): "If I could relocate Shaz to the UK, I wouldn't let him out of our reach. That probably says enough on its own." Got an idea? A project stuck halfway? Or just need someone who actually cares about your product? Hit that invite button or send me a message.
