Senior Mobile App Developer specializing in iOS (Objective-C/Swift/SwiftUI), React Native and Flutter with 11+ years of experience building production-grade mobile applications. I help startups and product teams to build scalable apps, integrate complex features, and ship reliable releases to the App Store and Google Play Store. Before full-time freelancing, I spent 9 years as a full-time mobile engineer - growing from Junior iOS Developer to Senior iOS and React Native Developer at a product-focused software company. I wasn't job-hopping. I was building. During those years I worked on real production apps, made architectural decisions, integrated hardware devices, and solved the kind of problems that appear only after an app reaches real users. In 2023 I moved into freelancing with one goal: bring the same engineering discipline and product mindset to companies that want more than average freelance work.

Most Flutter developers build generic apps. I focus on the hard stuff: health data platforms, Bluetooth LE & wearable integration, real-time WebRTC video, and AI-powered features. Top Rated Plus on Upwork, 100% Job Success. If you're building a mobile product that has to work — real-time vitals from a BLE wearable, an AI assistant inside your app, or video calls that don't drop on weak networks — that's exactly the kind of problem I solve. I've spent 9 years building mobile apps, starting as an Android native developer and moving into Flutter, which means I understand what's happening under the hood — not just the framework, but the platform beneath it. That foundation is why my apps stay fast, stable, and battery-friendly even in tough conditions. ⭐ Why clients work with me: Flutter apps that stay smooth even on low-end devices and poor internet connections Deep experience in the niches most developers avoid: medical/health data, Bluetooth LE & IoT device communication, WebRTC real-time video, and AI integration Clear weekly milestones and transparent progress, so you always know where your project stands Senior-level communication — I ask the right questions early and flag risks before they become problems Production mindset: clean architecture, proper state management, and code your next developer can actually maintain 🩺 Recent work: HealthGauge — BLE wearable integration with real-time vitals tracking and interactive health data visualizations (iOS + Android) AI-powered contact-center app on AWS that automates customer support workflows A senior-friendly video calling app with auto-answer, built to stay reliable on slow connections for elderly users Live solar-telemetry app integrating real-time IoT data for a German solar manufacturer Secure WebRTC video + audio calling app with in-call messaging across iOS, Android, and desktop 🛠️ Technical stack: Mobile: 9+ years building mobile apps — Android native (Java/Kotlin) → Flutter & Dart, iOS (Swift/Objective-C) AI: LLM integration via OpenAI & Claude APIs — in-app AI chat, smart/contextual responses, data-driven insights, and Firebase Generative AI State management: BLoC (preferred), Riverpod, GetX, Provider Backend: Firebase (Authentication, Firestore, Cloud Functions, Push Notifications/FCM, Analytics, Performance), Supabase, Node.js, REST & GraphQL APIs Cloud & real-time: AWS (Chime SDK, Lambda), WebRTC, push notifications, live chat IoT & hardware: Bluetooth Low Energy (BLE), ESP32, NRF, NFC, smartwatch SDKs, wearable device integrations Databases & local storage: Firestore, SQLite, Hive Payments: Stripe, PayPal, Razorpay Maps & location: Google Maps, Mapbox, Flutter Map Tooling: GitHub, Jira, Trello, CI/CD, Agile workflows 📦 30+ apps delivered across HealthTech & health monitoring, AI-powered apps, real-time communication (chat & video calls), fitness & sports, logistics & delivery, service-provider platforms, and fintech. How I work: I start by understanding your vision, users, and business goals — not just the feature list. I break the project into weekly milestones so progress is visible and predictable, share regular updates, and keep the codebase clean and documented throughout. When you build with me, you work directly with the engineer writing your code — no account managers, no hand-offs, no telephone game. You get honest technical advice, realistic timelines, and an app built to scale as your business grows. Whether you have a detailed spec, a rough Figma design, or just an idea on paper, I can help you turn it into a production-ready iOS and Android app from a single Flutter codebase — and I'm equally comfortable taking over and improving an existing Flutter project, fixing bugs, or refactoring messy code. 📩 Send me a message with your idea and I'll reply with honest, specific feedback on how I'd approach it — including the tech stack, timeline, and any risks I'd watch out for.
