I help founders, startups, and product teams turn an idea into a Flutter or React Native app that ships on time, keeps users, and moves the business. As a flutter developer and full stack developer, I own the whole path from idea to App Store, so you get one accountable partner instead of five contractors. Mobile App Development, done right, is how a rough idea becomes real traction. ❗️ What that looks like in numbers: 1M+ users and a 4.8⭐️ rating — that's where UpLife landed after we scaled it with Flutter App Development and AI Development. 10M+ users — that's how far Parlor grew as a cross-platform Mobile App Development build. $2.88M raised and 450K+ users — that's what GoFrendly reached with the right Mobile App Development partner. 🎯 Where I create the most value ▪️ Flutter App Development, done right — As a flutter app developer I ship clean, maintainable code and scalable architecture: smooth 60 FPS UI, role-based access (RBAC), user authentication, push notifications, in-app purchases and subscriptions, chat / messaging, analytics, and full App Store / Google Play launch. Flutter App Development is cross-platform, so you ship once instead of paying to build the same app twice. Across 400+ projects, flutter mobile app development with native depth in Swift (iOS) and Kotlin (Android) delivers production-ready apps, not demos. Whether you need flutter mobile app developer support for a fresh build or a rescue, Flutter App Development scales from a 2-week MVP to a multi-year product. ▪️ AI Development that earns its place — As an ai developer I build AI Development features that bring users back: AI assistants, smart onboarding, personalization, recommendations, image recognition, and context-aware journeys. Practical AI Development also means document processing, chat-based AI (ai chatbot developer work), and job application automation. If you want an ai software developer who ties AI Development to retention and revenue — not a trendy add-on — that's exactly what I do. ▪️ Full-stack support — As a full stack developer I cover Node.js, Python, FastAPI, Firebase, REST APIs and api development, plus cloud functions, admin dashboards, and role-based access. As a web developer I handle the surrounding web design, web-to-mobile conversion, and admin panels. React and react developer work on the front end, react native on mobile — fewer handoffs, faster decisions, and clean code across the stack. 📲 A few products I've shipped as a mobile app developer ✔️ UpLife — mental health app with an AI assistant & therapy recommendations. 1M+ users, 4.8⭐️ ✔️ Parlor — social audio platform, 10M+ users ✔️ GoFrendly — social network for women. 450K+ users, $2.88M raised ✔️ Notate — secure productivity app trusted by Bank of America, Citibank & 80+ companies ✔️ Mila Cares — connected HEPA air purifier app. 50K+ users, $1.58M raised ✔️ Fillrr — AI-powered document app, 4.9⭐️ ✔️ Photofy — content creation app, 100K+ users, 4.9⭐️ ⚡️ I respond in under 10 minutes during working hours. 🤝 Why founders keep coming back I treat your budget like my own and your deadline like a launch I'm personally on the hook for. As a mobile app developer and flutter developer I don't vanish after App Store approval - I stick around for real users, real reviews, real iteration. 90%+ of my work is repeat clients and referrals. If a flutter developer or mobile app developer once handed you a demo and disappeared, Mobile App Development that actually ships is the gap I fill. Need a full stack mobile app developer or a react native mobile app developer for the next build? Send me the details and I'll tell you honestly what it'll take. If you need Flutter App Development, React Native, full stack developer support, or AI Development from someone with a proven track record of shipping real products at scale, message me. Mobile App Development is what I do every day - let's make yours one of the wins. 🔑 Areas I cover: Flutter App Development • Mobile App Development • AI Development • flutter developer • flutter app developer • flutter mobile app development • flutter mobile app developer • mobile app developer • cross-platform app development • react native • react native mobile app developer • react developer • full stack developer • full stack mobile app developer • web developer • web design • api development • REST API integration • ai developer • ai chatbot developer • ai software developer • image recognition • job application automation • MVP development • App Store & Google Play deployment

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.

This React Native Developer has also designed and optimized 200+ WordPress and Shopify websites for SEO and conversion, working as both a Shopify and WordPress front-end developer. As a React Native Developer who understands the full product lifecycle, I integrate Auth0, Stripe payment systems, and blockchain modules while leveraging Webflow and Elementor for custom web experiences — delivering cohesive digital products from mobile app to web.

Most of my clients are in the UK, US, Australia, the Netherlands, and UAE, so I keep my hours overlapped with their time zones. You'll usually hear back from me within a few hours. ★ HERE'S WHAT I'M BEST AT ✔ Elementor Pro and custom builds. Pixel perfect, fully responsive, and clean Figma to WordPress conversions that stay easy to edit. ✔ WooCommerce stores that actually convert. Custom checkout, payment gateways like Stripe and Authorize.net, subscriptions, and product pages. ✔ WordPress with AI built in. Chatbots, content and workflow automation, plus custom API connections using OpenAI, Claude, and n8n. ✔ Speed and Core Web Vitals. 90+ PageSpeed with LCP, CLS, and INP all passing. ✔ Rescue jobs.

If the scope changes, we talk about it. It never just shows up on your invoice. ✔ You work with me directly on every project. No handoffs, no junior swapped in behind the scenes. ★ MY STACK WordPress, Elementor Pro, WooCommerce, ACF, PHP, JavaScript, REST API, Figma, OpenAI and Claude APIs, and n8n.
