⭐⭐⭐⭐⭐ "Gopi is a very hardworking and dedicated team member. She showed up every day with consistency and focus, and her commitment to our project never wavered. I highly recommend her to anyone seeking a reliable and driven contributor." (Upwork client, 344-hour React Native frontend engagement, 5-star close)
As a Senior React Native Developer with 8+ years of production experience, I build React Native mobile apps for iOS and Android as a single coherent codebase. Most "React Native developer" posts get bid by web React developers who treat mobile as a thin shell over a web app. That is not the same thing as knowing React Native CLI vs Expo trade-offs, native module debugging on Android, or App Store submission edge cases that kill 1.0 launches. I take work in React Native mobile only, not web React with mobile bolted on.

✅ React Native Animation and UI/UX: complex gesture handling, smooth transitions, React Native Tailwind styling, pixel-accurate interfaces matching design specs
✅ App Store and Play Store Submission: code signing, provisioning profiles, review compliance, TestFlight and Internal Testing rollouts that pass on first submission
✅ Native Module Integration: bridging native iOS and Android code where React Native alone cannot deliver, in-app purchases, push notifications, deep links
✅ React Native Codebase Refactoring: rescuing legacy React Native mobile codebases from previous developers, modernizing to current versions, eliminating tech debt before production scale
𝗪𝗛𝗢 𝗜 𝗪𝗢𝗥𝗞 𝗪𝗜𝗧𝗛
🎯 Founders and product teams launching React Native mobile apps in production, not prototypes
🎯 SaaS companies adding a mobile app to an existing web product where one developer needs to own the full mobile build without handoff friction
🎯 Agencies subcontracting React Native developer work where the delivery standard is App Store grade and timelines are real
🎯 Teams rescuing a legacy codebase from a previous React Native developer who left tech debt behind
🎯 Engagements of 4+ weeks minimum, 30+ hours per week, with decision authority on the client side
𝗠𝗬 𝗣𝗥𝗢𝗖𝗘𝗦𝗦
Architecture Review: 24-hour turnaround on a React Native CLI vs Expo decision, navigation and state management choice, plus React Native developer scope estimate

My Process 💪
Step 1 — Free brief + audit. Send your idea, prototype, Figma files, or existing codebase. As a React Native Developer and Full Stack Developer, I review architecture, scope, risk, and feasibility across mobile and web — no charge, no obligation. Most audits turn around within 24–48 hours.
Step 2 — AI-powered prototype. Using Claude Code, Cursor, and OpenAI/Gemini integrations, I build a working, testable React Native or React Next.js prototype in 3–7 days, not months — so you validate real demand before committing to full development. This is the same AI-driven approach that's cut manual workflows by 30–50% and shaved 30–40% off time-to-market on past projects.
Step 3 — Build. Full-stack build across React Native Mobile, React Native Expo, React Native Firebase, and web (React, Next.js, Node.js, Supabase/PostgreSQL, MongoDB), with weekly demos so you always know exactly what's shipped and what's next. Sprints run in 1–2 week cycles with clear, measurable milestones — the structure behind 100+ delivered projects and 60+ full production launches.
Step 4 — Launch + scale. Deployment (AWS, Google Cloud, or Azure), CI/CD, monitoring, and post-launch optimization — the same DevOps React Native process that's taken apps from 0 to 100K+ MAU, 99.9% uptime, and 5M+ requests/month, while cutting infra overhead by 35% and backend costs by 70%.
As a full-stack React Native Developer with 20,000+ hours of hands-on experience across mobile and web platforms, I specialize in React Native, Flutter, React.js, React Native Mobile, React Native Expo, React Native Firebase, React Native WebRTC to build mobile apps.

I don't just write React Native code. I ship apps people actually use. 1M+ downloads. 30+ countries. 200+ projects. 100% Job Success.
Most clients come to me when their React Native app is stuck, broken, or half-built and nobody else could finish it. Or when they need a mobile app developer who handles everything from first screen to App Store and Google Play launch. Some come with an MVP idea and need a react native developer who moves fast without cutting corners. Others come because their react native mobile app has performance issues or complex integrations nobody else could solve. I've been doing this for 8+ years, delivered 200+ projects, and the apps I've built as a mobile app developer now serve 590K+ users across 30+ countries.
WHAT I BUILD
As a react native developer and react native engineer I cover the full mobile lifecycle across 200+ shipped products:
✦ React Native mobile apps with Expo and CLI for iOS and Android
✦ React Native Expo MVPs shipped from first screen to App Store and Google Play
✦ React Native Firebase integrations — auth, Firestore, real-time sync, push notifications
✦ React Native Supabase backends and React Native Node.js APIs that scale with the product
✦ AI mobile app development with OpenAI API, real-time features, and on-device intelligence
✦ In-app purchases, RevenueCat subscriptions, AdMob, deep linking, and push notifications
✦ Native Swift and Kotlin modules and android kotlin integrations when cross-platform isn't enough
✦ App Store and Google Play submissions including rejections, TestFlight, and review handling
I work as a react native full stack developer so clients don't need to hire two separate people. Firebase, Supabase, and Node.js on the backend — one team, one codebase, one point of contact.
INDUSTRIES
I've shipped products as a mobile app developer and mobile application developer across multiple verticals. In Fintech and Crypto I built a trading platform with 590K+ registered users and 2M+ monthly visitors.

⭐ Top Rated | 6+ Years in React Native | 12 Projects Delivered on Upwork | 30+ React Native Apps Shipped Overall
🏅 React Native Specialist — iOS & Android from One Codebase
🏅 React Native, Expo, TypeScript, Node.js, Firebase, Supabase
🏅 AI-powered features: OpenAI & ChatGPT integration
🏅 Idea → design → build → App Store, handled by one person
🏅 MVPs, e-commerce, fintech, healthcare, ride sharing & food delivery apps
Most app ideas never make it past "we should build this." Not because the idea's bad — because turning it into something real takes more decisions than people expect: what to build first, what to skip for now, how it should actually work on a phone, and who can be trusted to build it right the first time.
That's the part I do. I've spent 6+ years building React Native apps — first as a developer at two dev studios, now full-time on Upwork — and shipped 30+ apps to real users, including AI-powered products, on-demand platforms, and niche tools across healthcare, fintech, and productivity. On Upwork specifically, I've completed 12 projects to a 5.0 rating. I work directly with you from a rough idea through to a live app on the App Store and Play Store — no separate designer, no separate backend dev, no gaps where things get lost.
🎯 WHAT I BUILD
REACT NATIVE APPS, START TO FINISH
You bring the idea — a description, a few reference apps you like, even just a problem you want solved. I turn it into a working React Native app that runs natively on iOS and Android from a single codebase, so you're not paying to build the same app twice.
AI FEATURES BUILT IN FROM THE START
Chat assistants, smart recommendations, AI-generated content — if your idea includes AI, I build it into the core of the app from day one instead of trying to bolt it on after the fact. I've shipped AI-powered apps before, including one built around AI avatars and guided AI coaching.
AN APP THAT ACTUALLY FEELS NATIVE
Smooth transitions, lists that don't stutter, navigation that responds instantly — the difference between an app that feels "made with React Native" and one that just feels like a good app comes down to these details, and I build with that in mind from the first screen.
BACKEND & INTEGRATIONS THAT FIT THE APP
Firebase, Supabase, Stripe, PayPal, custom APIs — I design the backend and the app together, so your data and your UI are never working against each other.
LAUNCH, HANDLED
I submit to the App Store and Play Store myself. You get a live app, not a finished project sitting in your downloads folder with no idea how to publish it.
🏆 WHAT CLIENTS SAY
"Hamza did an amazing job from start to finish. He managed the project perfectly, guided us through every step, and even handled the app store deployment himself."
— Client, AI Image/Video Generator App
"I worked with Hamza for the second time for React Native development, and he did an exceptional job both times."
— Client, Book Reading App (MVP)
"Hamza is a very professional React Native developer, very skilled, having developed the app very well. He communicates effectively and delivers on time."
— Client, Figma-to-React Native MVP Build
"Hamza delivered everything on time and with excellent attention to detail. He's skilled, reliable, and a pleasure to work with."
— Client, Realtor Mobile App
🏆 Top Rated on Upwork · 5.0 rating across every completed contract · IBM & Course Era certified in React Native
📩 LET'S TALK ABOUT YOUR IDEA
Message me with what you're picturing and roughly when you'd want it live. I'll tell you honestly what an MVP version could look like, what it'll cost, and whether your timeline is realistic — not just say yes to book the contract.
I reply within 0–4 hours and move fast once we start.
𝗛𝗢𝗪 𝗜 𝗪𝗢𝗥𝗞
First I get clear on what the app actually needs to do and who it's for — that conversation matters more than people think. Then I build in React Native with Expo, set up the backend in Firebase or Node.js, and connect whatever APIs the product needs, whether that's payments, AI, or something else. I keep the code clean enough that adding features later doesn't mean starting over. And when it's ready, I take it all the way to the App Store and Play Store myself.

I help ambitious founders launch scalable products with Mobile App Development, cutting technical debt by 40% and time-to-market by 3 months.
If you are looking for a React Native expert to bridge the gap between complex business requirements and a seamless user experience, you have found the right iOS Android Developer.
In today’s digital-first economy, a mobile app is your most significant customer touchpoint. It needs to be fast, stable, and intuitive. I have spent years refining my craft in Mobile App Development, focusing on building robust, cross-platform solutions that perform under pressure. Whether you are building an MVP or scaling an existing ecosystem, my goal is to ensure your product survives the challenges of growth while staying ahead of the competition.
When I approach Mobile App Development, I treat your project as if it were my own. I specialize in React Native because it allows for high-velocity iteration without sacrificing the native feel users demand. By leveraging TypeScript alongside Expo or bare React Native workflows, I create a Scalable architecture that ensures your app remains maintainable. I understand that your Requirements are unique from complex API integration with REST APIs and Supabase to real-time Firebase backends and intricate Push notifications. My role as your iOS Android Developer is to handle the heavy lifting so you can focus on strategy.
Quality Mobile App Development is about the entire lifecycle. My process covers everything from initial UI/UX implementation and Performance optimization to the final App Store and Google Play submission. I have navigated review guidelines for Apple and Google hundreds of times, meaning I know exactly what is required to get your app live without the headaches of repeated rejections. Whether we are utilizing Swift or Kotlin for native performance hooks or working deep in the Node.js stack for custom backends, I ensure the transition from code to user device is frictionless.
I am often looking for partners who value precision. My track record as an iOS Android Developer proves that I can handle the nuances of platforms. While my primary expertise lies in React Native, I bring a broad background in full stack developer methodologies, including Laravel, Python, and JavaScript. I have seen projects where a Flutter developer might have been a good fit, but I often demonstrate why a well-architected React Native solution offers better long-term flexibility for teams invested in the React ecosystem. My expertise extends to iOS Development, Android App Development, and integrating advanced Smartphone features like camera processing and biometric security.
My workflow is built for modern teams. Independent work is my standard. I prioritize API integration and Performance optimization as a Must-have rather than an afterthought. If you have an existing codebase that needs an audit, I am ready to identify bottlenecks in your Scalable architecture and polish your UI/UX implementation to drive conversion. I believe Mobile App Development should be a collaborative, transparent journey.
Beyond technical execution, I act as a product consultant. I help you decide which features are necessary for your v1, preventing "feature creep" that often delays launch. I have worked with everything from E commerce app development to complex SaaS solutions. If you are looking for an iOS Android Developer who understands that code is a business asset rather than a sunk cost, my approach will resonate with you.
In the world of App Development, documentation is critical. When I hand over a project, you are not left with "black box" code. You receive a fully documented repository that any future Mobile app developer can navigate immediately. I use Firebase for rapid prototyping and Supabase when deep relational data structures are needed. I take great pride in the Mobile App experiences I create. I’ve seen projects move from sketches to thousands of daily users.
I’m currently looking for innovative projects where my skills make a measurable difference. If you have an existing App Development hurdle, let’s solve it together. My communication is direct, and my focus is always on your outcome. From the first line of code to the final store approval, I am there to guide your project.
I’m available for a 30–60 minute consultation to review your React Native or mobile app development needs. We can align on technical direction, delivery approach, and realistic timelines, after which I’ll outline a clear execution plan and cost structure. I’d be glad to collaborate. Let’s connect and turn your ideas into a top-tier mobile product.

You shipped the app. Now it owns you.
Crashes you can't reproduce. An App Store rejection with no explanation. A cloud bill that doubled overnight. You're up at midnight patching code instead of growing the product.
That handoff point is my job. I'm a senior React Native Developer and Mobile App Developer who takes over production React Native apps: React Native rescue, React Native performance optimization, App Store approval, FastAPI backends, and cloud bills cut back to what you
🏆 𝗧𝗼𝗽 𝗥𝗮𝘁𝗲𝗱 𝗣𝗹𝘂𝘀, 100% Job Success across 49 projects
📊 $100K+ earned, 4,100+ tracked hours on Upwork
⚡ 40+ mobile apps and web applications shipped end to end
🔥 One React Native AI app serving 100,000+ users in production today
𝗪𝗛𝗢 𝗛𝗜𝗥𝗘𝗦 𝗠𝗘
⚡️ Founders whose app grew faster than the code. Users are showing up. The crashes showed up with them
⚡️ Teams whose previous React Native developer left a half-built Expo or Next.js product behind
⚡️ Founders with a vibe-coded MVP (Cursor, Lovable, Bolt, Replit, v0) that demos great and breaks in production
⚡️ Startups whose codebase won't survive technical due diligence before a raise
⚡️ Product teams starting a React Native mobile app that must be production-grade from day one, because they've been burned before
𝗪𝗛𝗔𝗧 𝗜 𝗙𝗜𝗫
⚡️ React Native Rescue: I take over legacy and AI-generated React Native codebases, tell you honestly what's worth keeping, and stabilize before scaling. Most apps don't need a rewrite. They need an engineer
⚡️ React Native Performance Optimization: the crash that only happens on Android. The list that janks at 200 items. Re-render storms from MobX and state management done wrong. I find it, I fix it, you watch the crash reports go quiet
⚡️ App Store Compliance: rejections decoded, TestFlight rollouts, provisioning untangled, resubmitted and approved
⚡️ Cloud Bill Reduction: Google Cloud and Firebase bills usually grow from bad queries, not growth. I find the N+1 reads and runaway functions and cut the bill down to what the product actually needs
⚡️ React Native AI Integration: as an AI Developer I build assistants, voice features with Whisper, and LLM features with OpenAI and Claude that behave with real users, not just in demos
⚡️ React Native FastAPI Backend: as a FastAPI Developer I own the Python APIs, PostgreSQL, background jobs, Docker deployments, and Google Cloud infrastructure behind the mobile app. One developer, whole product
⚡️ React Native Mobile App Development: when you need it built right the first time. Production React Native CLI and React Native Expo builds for iOS and Android, TypeScript throughout, store-ready
𝗥𝗘𝗔𝗟 𝗣𝗥𝗢𝗝𝗘𝗖𝗧𝗦
🔶 React Native AI coaching app: Whisper, OpenAI, FastAPI, Firebase, Google Cloud. Multi-brand architecture, 100,000+ users, still maintained by me today
🔶 React Native rescue: previous developer gone, CI broken, database broken, auth broken. Migrated repos, stabilized production, then shipped new features on top
🔶 React Native performance audit: diagnosed MobX rendering problems as an external React Native consultant, reviewed architecture and PRs. Performance jumped. No rewrite needed
🔶 Internal engineering systems: automation on Google Kubernetes Engine, Playwright infrastructure, Slack and CRM integrations
𝗦𝗧𝗔𝗖𝗞
⚡️ Mobile App Development: React Native, React Native Expo, TypeScript, JavaScript
⚡️ Web App Development: Next.js, React, SaaS
⚡️ Backend Development: FastAPI, Python, Node.js, Docker, GitHub CI/CD
⚡️ Cloud Infrastructure: Google Cloud Platform (GCP), Firebase, PostgreSQL
⚡️ AI Development: OpenAI, Claude, Whisper, LLM integration, semantic search
𝗛𝗢𝗪 𝗜 𝗪𝗢𝗥𝗞
⚡️Straight answers first: send your repo or live app, and within hours you know what's broken, what's salvageable, and what it costs to fix. Before you spend anything
⚡️ Communication that doesn't disappear: daily updates, standup calls if you want them, no 12-hour silences
⚡️Ship and stay: TestFlight, App Store and Play Store submission, documentation, monitoring. Around 90% of my clients come back. The difficult part is exactly why they hired me
𝗡𝗘𝗫𝗧 𝗦𝗧𝗘𝗣
Tell me where it hurts. Repository, live app, or two sentences about what's breaking. You'll get an honest answer, not a pitch.
