AI-Native Mobile App Developer | React Native, Flutter | iOS, Android

I’m passionate about mobile apps and everything that goes into building a great one. My experience goes beyond coding. I understand what it takes to turn an app idea into a successful product, from strategy and UX/UI design to marketing, monetization, analytics, and growth. I only take on a few projects at a time, so I can stay closely involved in each one. Drop me a message with a few details about your project, and let’s see if we’re a good match. 💼 𝗦𝗲𝗿𝘃𝗶𝗰𝗲𝘀 𝗢𝗳𝗳𝗲𝗿𝗲𝗱 → Mobile App Development → MVP Development → AI Integrations & AI Agents → Custom Code Development → UI/UX Design → Consultations 📱 𝗔𝗽𝗽𝘀 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗱 → E-commerce Apps → Learning platforms → Booking apps → Marketplaces → CRM Systems → Social Networks → Mindfulness Apps → Fitness Apps → Travel Apps → AI Apps → Internal Apps ⚙️ 𝗙𝗲𝗮𝘁𝘂𝗿𝗲𝘀 𝗜𝗺𝗽𝗹𝗲𝗺𝗲𝗻𝘁𝗲𝗱 → User Authentication → In-app Purchases → Paywalls → API Integrations → Onboarding Flows → Geolocation → Push Notifications → Payment Gateway Integrations → User Profiles → Ratings & Reviews → Video & Audio Integration → Analytics Integration → Notifications → Admin Panels → AI Integrations → AI Agents 🛠️ Tech stack: React Native, Flutter, Supabase, Firebase, Neon, PostgreSQL, TypeScript, Expo, Dart, Clerk, AWS, Google Cloud, Sentry, Amplitude, Codemagic, Fastlane, Revenue Cat, Superwall, AppsFlyer, Adjust, Branch, Posthog, Resend, Cursor, Flutterflow, Adalo, Make, Zapier, n8n, Mixpanel, Twilio, Stripe, Postman, Canva, Figma, Miro, Notion, Open AI, Anthropic, Google Gemini, Claude Code, Cursor, Replit, Lovable, Vercel ⚡⚡⚡ Special rates available for long-term and large-scale projects ⚡⚡⚡
