Senior Flutter Developer with 5+ years of experience delivering production-ready mobile and web applications used by hundreds of thousands of real users.
I've built and shipped apps that crossed 500,000+ downloads — including Simsim, a live production app trusted by a large and active user base. I don't just write code — I build scalable, maintainable products that perform at scale.
My core expertise is Flutter — I've shipped cross-platform apps for Android and iOS that handle real-time systems, complex state management, and high-traffic production environments. Alongside Flutter, I build fast, modern web apps using React.js and Next.js.
What I bring to your project:
- Senior-level Flutter development (Android & iOS) with clean architecture — BLoC, MVVM, Provider
- React.js & Next.js web applications — fast, SEO-optimized, and production-grade
- Firebase ecosystem — Auth, Firestore, Realtime DB, Cloud Functions, FCM push notifications
- Real-time features — live chat, GPS tracking, WebSockets
- Payment gateways — Stripe, PayPal, and regional integrations
- Google Maps, location services & geofencing
REST API integration, performance optimization & app maintenance
Tech Stack: Flutter / Dart · React.js · Next.js · Firebase · Tailwind CSS · WebSockets · REST APIs · Android (Java)
As a senior developer, I take full ownership of my work — from architecture decisions to delivery. I communicate clearly, meet deadlines, and treat your project like my own. If you're looking for someone who goes beyond writing code and actually solves problems — let's talk.

Mobile applications should do more than look good—they should solve real business problems, streamline operations, and grow with your business.
I'm a Flutter Mobile App Developer with 4+ years of professional experience helping clients build, maintain, and improve Android and iOS applications. I transform ideas and business requirements into production-ready mobile solutions that are reliable, scalable, and built for long-term success.
I've contributed to 10+ mobile applications across e-commerce, merchant management, order management, legal services, productivity tools, and custom business platforms. From translating Figma designs into responsive Flutter interfaces to integrating REST APIs, Firebase, Google Maps, push notifications, local storage, and preparing applications for Google Play, I build solutions that perform reliably in real-world environments.
I'm comfortable joining projects at any stage—whether building a new application, extending existing functionality, or taking over ongoing development. I focus on implementing new features, integrating APIs, optimizing performance, resolving complex issues, and writing clean, maintainable code that supports future growth.
I believe successful projects are built through clear communication, taking ownership of my work, and understanding business goals. I collaborate closely with designers and backend developers to ensure every feature delivers value to both the client and the end user.
Whether you're building a new Flutter application, improving an existing product, or looking for a reliable developer to strengthen your team, I'd be happy to discuss how I can contribute to your project.
