Most mobile developers stop at the frontend.
I also build the AI and automation layer behind the app, including chatbots, voice agents, RAG-based search, and backend workflow automation with n8n, Make, and Zapier.
So what you get is a working product with real intelligence built in, not just a UI wrapped around a static backend.

I leverage AI tools like Claude Code, Cursor AI, and ChatGPT to accelerate mobile app development, architecture planning, debugging, prototyping, integrations, maintenance, and shipping.
I’ve professionally designed, built, managed, and maintained 100+ full stack mobile apps, SaaS apps, AI-powered applications, marketplaces, automation systems, and custom software solutions using React Native, Flutter, FlutterFlow, Adalo, React, Next.js, Node.js, JavaScript, APIs, databases, cloud platforms, and modern AI-assisted development workflows.
My mobile app expertise includes:
📱 iOS app development
📱 Android app development
📱 React Native development
📱 Flutter & FlutterFlow development
📱 Mobile app maintenance & management
📱 App updates, bug fixes, and performance optimization
📱 AI-powered mobile apps
📱 Social media apps

• jumping into messy codebases and fixing them
• making technical decisions independently
🤝 Let’s work together
