I have been building reliable mobile apps across iOS and Android for the past 5 years, focusing on production-ready apps that scale from MVP to full products used by real businesses.
I work across Flutter and React Native, and also develop native modules in Swift and Kotlin when platform-specific functionality is required.
What I Build
Cross-platform mobile apps using Flutter and React Native (Expo, TypeScript)
Native iOS apps with SwiftUI and Android apps with Kotlin when needed
AI-powered mobile apps — chatbots, smart recommendations, LLM features
Real-time and video calling apps — WebRTC and live data systems
Maps and location apps — Google Maps, Mapbox, GPS tracking
MVPs — production-ready in weeks and built to scale
SaaS, FinTech, IoT, inventory, on-demand, and business apps
Technical Stack
Mobile: Flutter, React Native (Expo), SwiftUI, TypeScript, Native Modules (Swift, Kotlin)
AI: OpenAI API, LLM integration, AI chatbots, recommendations
Maps: Google Maps SDK, Mapbox, geolocation, GPS tracking
Real-time & Video: WebRTC, real-time communication systems
Backend: Node.js, NestJS, REST APIs
Database: MySQL, MongoDB, Firebase, Supabase, Redis
Payments: RevenueCat, in-app purchases, Stripe
Integrations: BLE, IoT, push notifications, text-to-audio
Deployment: App Store, Google Play, CI/CD, GitHub Actions, EAS Build, Firebase Analytics, AWS
What Sets Me Apart
I focus on building production systems, not just app screens.
My work often involves:
Mobile apps with an offline-first architecture that work without the internet
AI features that add real product value
BLE and IoT hardware integrations with a mobile app.
Real-time communication and video platforms based on a mobile app.
MVPs that are built clean, so they don’t need to be rewritten later
I have shipped mobile apps involving live data, device communication, and scalable backend systems where reliability matters.
MVP Development
If you need to validate an idea quickly, I can build lean, production-ready MVPs in weeks, not months.
The architecture is designed from day one so the mobile app can scale without being rebuilt.
How I Work
Clear project scoping with realistic timelines
Weekly progress updates with working demos
Thorough testing before delivery
App Store and Google Play submission support
Ongoing support and post-launch updates
Industries
SaaS, FinTech, IoT, On-demand, Inventory, Real estate, Healthcare, Business productivity
