Hire the Best Sunshine App Sunshine Specialists

Your AI-built app got you 80% there. I'm the engineer who ships the last 20% and makes it production-ready. I'm a Senior Flutter & Node.js developer with 400+ completed Upwork projects, $200K+ earned, and a Top Rated Plus badge (top 3% on Upwork). For 6+ years, I've helped startups and founders turn ideas and half-finished AI-generated codebases into polished apps on the App Store and Google Play. 🔧 WHAT I DO BEST 1️⃣ Vibe Code Rescue Built your app with Cursor, Bolt, Lovable, or FlutterFlow AI and hit a wall? I audit, fix, and complete vibe-coded apps: broken state management, security holes, failing builds, App Store rejections. Recent clients came to me exactly for this: audits, bug fixes, and "please finish my app." 2️⃣ AI App Development I build AI-powered mobile apps end-to-end: ChatGPT, Claude, and Gemini API integrations, AI voice companions, chatbots, AI image and video features, and AI SaaS platforms with subscription billing. 3️⃣ Full Stack Flutter Apps From Figma to store launch. Flutter and FlutterFlow front end, Node.js + Express backend, MongoDB, Firebase, and Supabase, real-time features, push notifications, and admin panels. 💳 Integrations I ship regularly: Stripe, RevenueCat (in-app subscriptions), LiveKit (real-time audio and video), Firebase, AWS, Google Maps, OpenAI and Claude APIs, social logins, and payment gateways. 📱 RECENT WORK ✅ AI voice companion app (iOS) with real-time voice conversations and an LLM backend ✅ Crypto P2P payment app, an active long-term client since 2024 ✅ Two-sided service marketplace MVP built in FlutterFlow and launched in weeks ✅ Customer care app audit and completion for a US-based business ✅ Live GPS tracking apps for iOS and Android ✅ Multiple app audits and rescues for founders stuck mid-build 🛠️ TECHNICAL SKILLS ✅ Flutter, Dart, FlutterFlow, and native iOS and Android knowledge ✅ Node.js, Express, REST APIs, and WebSockets ✅ MongoDB, Firebase, Supabase, MySQL, and SQLite ✅ State management: Bloc, Provider, Riverpod, and GetX ✅ Clean architecture, reusable components, and Git version control ✅ App Store and Google Play publishing, including review issue fixes ✅ Performance optimization, offline storage, and push notifications 📋 MY WORKFLOW Step 1: Discovery call or chat. We discuss your idea, your existing app, or your requirements. I ask the right questions so nothing surprises us later. Step 2: Honest assessment and plan. You get a clear scope, a realistic timeline, and a milestone breakdown before any money moves. For rescues, I first audit the codebase and send you a written report of what's broken and what it costs to fix. Step 3: Milestone-based delivery. I break work into small milestones, so you see progress every few days, not once a month. Each milestone ends with a working build you can test on your own phone via TestFlight or APK. Step 4: Regular updates. Daily or every other day progress messages, weekly video calls if you want them, and Loom recordings of every feature so you always know exactly where things stand. Step 5: Testing and polish. I test on real devices, fix edge cases, and tune performance before we ever talk about launch. 🚢 DEPLOYMENT AND APP STORE APPROVAL Publishing is where many projects die, so I handle it fully: ✅ Apple App Store and Google Play submission from start to approval ✅ Fixing rejections: guideline 4.3 spam flags, missing privacy details, crashing on review, sign in requirements, and in app purchase issues ✅ App Store Connect and Play Console setup, screenshots, metadata, and privacy policies ✅ CI and release builds, versioning, and staged rollouts ✅ Post launch monitoring and crash fixes If your app was already rejected, send me the rejection message and I'll tell you exactly how to get it approved. 💰 ENGAGEMENT AND RATES I work both hourly and fixed-price with milestones. For fixed projects, you only pay when a milestone is delivered and approved. For ongoing work, many clients keep me on hourly for maintenance and new features after launch. I'm flexible with time zones and overlap comfortably with US and EU working hours. ⭐ WHY CLIENTS COME BACK ✅ 94% Job Success Score across 220+ reviews ✅ I take ownership. You get working software, not excuses ✅ Clear communication, fluent English, and overlap with US and EU hours ✅ A small senior team behind me, so projects never stall ✅ Honest estimates. If something is not worth building, I tell you before you spend money 🚀 HOW WE START Send me your app, repo, or idea. I'll review it and give you an honest assessment: what's broken, what it takes to fix or build, and a realistic timeline. No inflated promises. Whether you need a rescue, a new AI app, or a long-term development partner, message me and let's talk about your project. Let's ship something your users will love.

Clean UX, stable performance and consistent 5-star delivery throughout. Fitness iOS app with AI — integrated LLM API features into a React Native app running on device in production. Full chain from API integration through to structured output on screen. Apple Watch companion — built a health and performance app for wearable that connects watch data to the main iOS app. Most React Native developers can't touch this level of native integration. Live production crash fix — a client's Expo app was crashing in production. Fixed it before they noticed. Their words: "fixed the bug before I even noticed it. Quality and delivery time were beyond my expectations." Long-term React Native project — maintaining and shipping new features for over a year with consistent 5-star delivery across every milestone. ⚙️ HOW I WORK I communicate early when something is off and flag problems before they become crashes.
