I’m a Flutter & FlutterFlow Developer specializing in AI integrations, Firebase, APIs, and production-ready mobile applications. With 4+ 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.

Mobile App Developer with 10+ years of experience building native iOS and cross-platform mobile apps using Swift, SwiftUI, UIKit, and Flutter. I build, fix, modernize, and launch production-ready mobile apps with Firebase, REST APIs, AI integrations, payments, and subscriptions. I help founders and businesses turn ideas, existing apps, and product requirements into reliable mobile products — from development and architecture to testing, bug fixing, and App Store / Google Play deployment. Mobile app development - Native iOS apps with Swift, SwiftUI, UIKit, and Objective-C - Cross-platform Flutter apps for iOS and Android - Firebase Authentication, Firestore, Realtime Database, Analytics, and push notifications - REST APIs, third-party SDKs, authentication, and backend integrations - Payments, subscriptions, and in-app purchase integrations - AI-powered mobile features and API integrations - App Store, Google Play, TestFlight, and production releases - Bug fixing, crash investigation, performance optimization, and legacy app modernization I can help if you are: - Building a mobile app from scratch - Fixing or improving an existing iOS or Flutter application - Migrating or modernizing an older mobile codebase - Preparing an app for App Store or Google Play submission - Adding Firebase, APIs, payments, subscriptions, notifications, or AI features - Improving app stability, performance, and user experience - Looking for a long-term mobile developer for ongoing features and maintenance I don't just implement isolated tasks. I can help review the existing product, understand the technical requirements, identify risks, and choose a practical approach before development. You can expect clear communication, realistic estimates, clean and maintainable code, regular progress updates, and properly tested builds before release. I have worked on mobile products ranging from focused iOS applications to larger platforms involving mobile apps, backend integrations, payments, dashboards, and production releases. If you have an existing app, new idea, bug list, Figma designs, API documentation, or product requirements, send them over. I can review the scope and recommend the best technical approach.

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.
