Got a great app idea but no clear path to launch? I build AI-powered web and mobile apps that actually ship - and actually work. 🤖 AI-Powered Apps | 📱 Mobile & Full-Stack | 🔄 Legacy Migration | ⚙️ Optimization ✅ 60+ Projects Delivered | 🏆 Upwork Top Performer | 🚀 Ready to Start ASAP I’m an AI-native full stack developer and AI-native mobile developer with 8+ years of experience building, fixing, and scaling mobile and web products for startups and growing companies. I combine mobile app development, full-stack development, and AI integration to deliver applications that are not just usable, but intelligent, automated, and ready for real-world business workflows. My background covers Flutter, React, React Native, .NET, native iOS/Android, and backend-connected products, so I can work across the entire stack - from AI-powered applications and internal tools & dashboards with AI analytics, down to stable APIs, databases, and deployment. That mix lets me act as both a mobile developer and a full stack developer who can connect the app, backend, and AI logic without slowing delivery down. 💡 How I work with AI-native products 🔹 I focus on products that need more than a static UI - apps that require AI automation, smart workflows, and real business integration: 🔹 Designing and building AI-powered applications where the app does real work, not just displays data. 🔹 Implementing AI integration with tools like ChatGPT, Claude, Codex and other LLMs. 🔹 Building AI workflow automation that connects apps to CRMs, ERPs, and internal tools. 🔹 Creating AI agents that can assist users, automate routine tasks, and interact with APIs. 🔹 Adding AI analytics layers to internal tools & dashboards, so teams see insights, not just raw numbers. In these projects I pay close attention to data flow, security, monitoring, and user experience, so the AI features don’t just look smart in a demo, but stay reliable in production. 💡 Areas I specialize in 🔹 AI & automation 🔹 AI-native full stack development (web + mobile) 🔹 AI-native mobile development (Flutter, React Native, .NET MAUI, native) 🔹 AI integration (ChatGPT, Claude, Codex, other LLM APIs) 🔹 AI-powered applications for B2B SaaS and internal tools 🔹 AI automation for B2B SaaS (workflows, triggers, smart notifications) 🔹 AI workflow automation (back-office, operations, support) 🔹 AI agent development (assistants for users, ops, internal teams) 🔹 Internal tools & dashboards with AI analytics and insights 🔹 SaaS, MVPs & product builds 🔹 SaaS and startup MVP development - from idea to production-ready release 🔹 Product discovery support (technical scoping, roadmap, architecture options) 🔹 Multi-tenant SaaS architecture and integration with existing systems 🔹 Mobile application & cross-platform application 🔹 Cross platform mobile app architecture - Flutter, React Native, .NET MAUI 🔹Mobile app development for iOS and Android - stable, performant, and maintainable 🔹 Native app development – Swift / SwiftUI, Kotlin / Android 🔹 App modernization and legacy migration - Xamarin to .NET MAUI, Flutter, or React Native 🔹 Backend, APIs & connectivity 🔹 API integration and backend connectivity – REST, real-time features, secure data flow 🔹 Full stack development – connecting mobile apps with APIs, web dashboards, and cloud services 🔹 Internal dashboards and admin panels – including AI analytics and reporting 🔹 Code quality, reliability & growth 🔹 Continuous delivery, refactoring, and codebase optimization 🔹 Stabilizing fragile codebases and preparing them for scale 🔹 Introducing clean architecture and practical patterns without over-complicating the stack 🛠️ Technologies I work with ⚙️ Mobile: Flutter, React Native, .NET MAUI, Xamarin, Swift/SwiftUI, Kotlin, native iOS + Android ⚙️ Web & backend: React, Next.js, Node.js, .NET Core, TypeScript, JavaScript, REST APIs ⚙️ AI & automation: ChatGPT, Claude, Codex, LLM APIs, AI agents, AI workflow automation ⚙️ Cloud & integration: Firebase, REST/GraphQL APIs, third-party integrations, internal tools, dashboards 🤝 When I’m a good fit I’m a strong fit when you need a mobile or full stack developer who can: ⭐️ Think beyond screens and buttons and help design the full product. ⭐️ Build AI-native or AI-augmented products, not just wrap a UI around someone else’s logic. ⭐️ Connect mobile, web, backend, and AI into one coherent system. ⭐️ Keep the codebase clean enough that future developers won’t hate you for shipping fast. Whether your goal is a new MVP, a modern AI-powered app, a cross platform mobile product, or a smarter internal tool, I focus on stability, maintainability, and real business outcomes, not just features. 🚀If you need an AI-native full stack developer, AI-native mobile developer, Flutter / React Native / .NET MAUI / Swift / Kotlin developer, or a full stack developer who can integrate AI, build agents, and ship reliable apps - send a message or invite me, and let’s get started today!

Hi, I'm Ranjit — a HIPAA certified mobile and PWA developer who helps healthcare, wellness, and fitness founders turn their web prototypes into production-ready iOS and Android apps without rebuilding from scratch. If you've built something on Lovable, Base44, or Replit and now need it live on the App Store and Play Store, that's exactly what I do. Using Capacitor, I wrap your existing PWA into native iOS and Android apps — preserving your codebase, cutting your timeline by 60–70%, and giving you full access to native features (push notifications, camera, HealthKit/Google Fit, biometric auth, in-app purchases, background sync). Where I focus: Women's Health & Fertility — IVF/IUI cycle tracking, period & ovulation logging, clinic portals, telehealth flows Gym & Fitness — Coaching apps, workout tracking, multi-location gym management (attendance, billing, trainer portals) Wellness & Nutrition — Mindfulness, habit tracking, meal planning, hydration, sleep Healthcare adjacent — HIPAA-aware data handling, secure auth, EHR/clinic integrations What you get working with me: A working app on TestFlight / Internal Testing within 2–3 weeks (typical PWA-to-mobile conversion) Full App Store and Play Store submission handled end-to-end (certificates, provisioning, store listings, review responses) Native features bolted on cleanly — push notifications (Firebase/OneSignal), offline mode, biometric login, native sharing, deep linking Code that your future team can actually maintain — clear structure, documentation, and a deployment guide My stack: React Native, Capacitor, Ionic, React, Next.js, TypeScript, Firebase, Supabase, REST/GraphQL APIs, Stripe/RevenueCat for subscriptions. I respond within a few hours, work in overlap with US/EU time zones, and I'd rather start with a 20-minute discovery call than send you a generic proposal. If you've got a PWA, prototype, or web app that needs to become a real mobile product — let's talk.
