I build production-ready mobile apps that combine React Native or Flutter with AI, scalable backends, payments, analytics, and real product infrastructure. Over the past 8+ years, I’ve helped startups, SaaS companies, and growing businesses build and launch 50+ mobile apps across the App Store and Google Play, reaching 1M+ combined users. My focus goes beyond writing code. I help clients build mobile products that are reliable, scalable, measurable, and designed to improve after launch. ### What I can help you build ✅ **AI & LLM-Powered Mobile Apps** AI assistants, conversational apps, OpenAI / GPT integrations, RAG, smart search, AI recommendations, speech-to-text, transcription, AI workflows, and automation. ✅ **React Native & Flutter Apps** Cross-platform iOS and Android apps, MVPs, complete product builds, redesigns, performance improvements, and existing codebase upgrades. ✅ **Backend & API Development** Node.js, Laravel, Firebase, REST APIs, authentication, databases, cloud functions, storage, push notifications, and third-party integrations. ✅ **Payments, Subscriptions & Monetization** Stripe, Stripe Connect, RevenueCat, Apple Pay, Google Pay, in-app purchases, subscriptions, paywalls, free trials, recurring billing, and marketplace payouts. ✅ **Product Analytics & Growth** Firebase Analytics, Crashlytics, event tracking, onboarding funnels, conversion tracking, retention analysis, dashboards, A/B testing support, and data-backed UX improvements. ✅ **Common Mobile App Features** Authentication, social login, user profiles, chat, live features, push notifications, maps, location tracking, booking systems, calendars, file uploads, deep links, and App Store / Google Play deployment. ### Products I commonly work on • AI assistants and AI-powered apps • SaaS and B2B mobile products • E-commerce and marketplace apps • Social media and community platforms • Live streaming and live commerce apps • Booking and on-demand service apps • Subscription-based mobile apps • Location and map-based applications ### Tech Stack **Mobile:** React Native, Flutter, Kotlin, Swift, SwiftUI **Backend:** Node.js, Laravel, Firebase, REST APIs **Databases:** Firestore, MySQL, MongoDB, Realtime Database **AI:** OpenAI, GPT APIs, RAG, speech-to-text, transcription, AI workflows **Analytics:** Firebase Analytics, Google Analytics, Crashlytics, funnels, event tracking **Payments:** Stripe, Stripe Connect, RevenueCat, Apple Pay, Google Pay **Maps:** Google Maps, Google Places API, Mapbox **Cloud:** Firebase, Google Cloud, AWS **Tools:** Figma, GitHub, App Store Connect, Google Play Console Whether you’re building a new AI-powered mobile app, launching an MVP, modernizing an existing product, adding subscriptions or payments, or improving analytics and retention, I can help take it from idea to production.
