🏆 Trusted Mobile App Developer | 253+ Projects Launched | 87% Repeat Clients
Most developers write code. I direct it.
I'm Ali, a mobile engineer and product architect with 13+ years of experience building native iOS, native Android, and cross-platform apps. But the thing that actually separates me from most developers right now is how I work.
I build with AI tools the way a pilot uses autopilot. I'm in full control, I deeply understand what's happening at every layer, and I move a lot faster because of it.
A feature that takes a traditional developer a week to build? I can ship it in a day. Not because I'm cutting corners, but because I've fully integrated AI coding tools into my workflow and I know exactly how to use them without losing quality.
- The tools I work with daily:
OpenAI Codex, Claude Code by Anthropic, Google Antigrativy, Gemini, Cursor, and GitHub Copilot.
These aren't toys I'm experimenting with. They're part of how I work on every single project.
But here's the thing most people miss about AI-assisted development. Speed without expertise is actually dangerous. You still need someone who knows the platforms deeply, understands what App Store reviewers flag, knows how Google Play policies work, and can catch what the AI gets wrong. That's where my 13 years come in.
I know native Swift and SwiftUI for iOS. I know native Kotlin and Jetpack Compose for Android. I also work in Flutter and React Native when that's the right call. Most mobile freelancers only do cross-platform. I can go fully native when the product actually needs it, which matters more than most clients realize until they've been burned.
- What I build:
Native iOS apps using Swift and SwiftUI.
Native Android apps using Kotlin and Jetpack Compose.
Cross-platform apps in Flutter and React Native.
AI-powered features like in-app assistants, voice interfaces, personalized onboarding, and smart recommendation engines.
Full MVPs from zero to App Store. And cross-platform to native migrations when performance or platform depth demands the real thing.
- My full stack:
Mobile: Swift, SwiftUI, Kotlin, Jetpack Compose, Flutter, React Native
AI Dev Tools: Rork, Vibecode.dev, Cursor, OpenAI Codex, Claude, Gemini, GitHub Copilot
AI Features: GPT-4o, Claude API, Gemini API, LangChain, Whisper, ElevenLabs
Backend: Firebase, Supabase, Node.js, REST, GraphQL
Payments: RevenueCat, Stripe, StoreKit, Google Play Billing
Stores: App Store Connect, Google Play Console, TestFlight
I've also served as CTO and technical lead for multiple startups, so I think beyond the ticket. I'm not just building what's in the brief. I'm thinking about what the product actually needs to succeed.
I keep my client list small on purpose. Every project gets my full attention.
If you want a mobile app built properly, delivered fast, and by someone who has actually done this before, let's talk.
$200K+ earned on Upwork. 100% Job Success Score. Top Rated Plus.
Send me a message and tell me what you're building. I'll be honest about whether I'm the right fit and how quickly I can get it done.

AI-ASSISTED DEVELOPMENT
I use Claude Code, Cursor, GitHub Copilot, Lovable, and Base44 to accelerate delivery while maintaining production engineering standards.
Every project receives proper attention to architecture, scalability, secure data access, maintainable code, testing, monitoring, performance, and deployment readiness.
TESTING AND QUALITY
My testing process includes:
• Unit testing
• Integration testing
• End-to-end testing
• Visual regression testing
• Approximately 80% automated test coverage where practical

👋 Hi, I’m a 🚀 🚀 🚀 🥇Top Rated Plus Full-Stack Developer 🚀 🚀 🚀 with over 17 years of hands-on experience building powerful, user-friendly web and mobile applications — from idea to launch and beyond.
I’ve successfully completed 🔥 20+ long-term projects 🔥🔥🔥 on Upwork, partnering with clients from around the world to deliver solutions that are not only technically sound but aligned with real business goals.
Whether you’re a startup looking for an MVP, or an established company needing to scale and refactor a legacy system — I’m here to help make it happen, smoothly and efficiently.
Here’s what it’s like working with me:
🧩 I figure things out. Fast. From legacy spaghetti code to shiny new stacks — I dive in, untangle, optimize, and deliver.
📢 I communicate like a human. You’ll never get vague tech talk from me. I keep you in the loop, explain the "why" behind choices, and always deliver with clarity.
🛠️ Full-stack is my comfort zone. Whether I’m building snappy UIs or crafting efficient backends, I move comfortably across the stack — and make it all work together like a dream.
💡 I care about what we’re building. Your goals are my goals. I’ll offer ideas, challenge assumptions, and help make smarter decisions (not just code what’s asked).
🤹 I’m independent but team-friendly. I play well with others, but I’m also happy to take full ownership when needed and just get things done.
🔄 Always learning, never stuck. New tools, new frameworks, weird edge cases — bring it on.
Long story short: I love building things that are useful, clean, scalable, and even a little fun. If you're looking for a dev who’s reliable, thoughtful, and maybe even a little witty — let’s connect!
