👋 Mobile App Developer for iOS and Android with 15 years in Xcode and Android Studio and 100+ apps shipped, from new builds to takeovers of existing apps. ⭐ Mobile App Developer | Mobile App Development | Ios developer | Android developer | Flutter Top Rated Plus | 100% Job Success | $600K+ earned | 112 jobs | 12,391 hours | 15+ years | 8 industries I am a Mobile App Developer and CTO-level engineer with 112 closed contracts and 12,391 tracked hours here. Native Ios app work in Swift, Android in Kotlin, cross-platform Flutter and React native, plus the backend under all of it. 📱 Mobile app development and mobile application developer, 100+ apps As a full-cycle Mobile App Developer I take products from architecture to store release, 100+ times. A mobile application developer who only writes screens leaves an app nobody can extend. On a fitness product, moving startup work off the network path cut cold start to a third and lifted day-1 activation. Mobile app development here means the app and the API under it, handed over as code your team reads without a rewrite. 🍎 Ios developer, Swift ios developer, 3 Apple platforms As an Ios developer I build native Swift and SwiftUI apps across 3 Apple platforms: iPhone, iPad and Mac. iPad App Development is its own job, not a stretched phone layout: on a medical product the tablet build became the one clinicians used. A Swift ios developer earns the fee at App Store review: privacy manifests, permissions, In-App Purchases rules, and the 4 reasons behind most first rejections. Your Ios app clears review as a launch date, not as a gamble. 🤖 Android developer, Android kotlin, Android developer kotlin As an Android developer I build native Kotlin apps with Jetpack Compose, phone to foldable. Android App Development means Play policy, background limits and 3 Smartphone and tablet classes that break layouts drawn at 1 width. 2 vitals thresholds decide your listing, ANR and crash rate, and on a social build reworking background sync brought both under the bar in one release. An Android developer kotlin project ships with the release pipeline configured, not as a zip file. 🔀 Flutter developer, React native, Hybrid App Development As a Flutter developer I ship 1 codebase to 2 stores when 2 native builds are not worth it, and I say which case yours is. On a marketplace product that call cut the build budget roughly in half against two native apps. React native the same. Hybrid App Development is a cost decision, and Native App Development wins whenever maps or media make it win. If your team works with a Flutter mobile app developer india based or anywhere else, my code is documented for handover. 🧠 Ai mobile app developer, AI Mobile App Development, 1 cost model As an Ai mobile app developer I ship LLM agents, computer vision, OCR, voice and RAG inside real apps on the OpenAI and Claude APIs. AI App Development fails on the invoice sooner than on the code, so 1 rule holds: I model running cost per 1,000 users before we build. Caching, prompt trimming and a cheaper model for routine calls are the 3 levers, and on a music product they cut the monthly bill to a fraction of the first estimate. 🔎 Mobile app development code audit expert, 6 areas As a mobile app development code audit expert I review 6 areas: architecture, dependencies, memory and performance, crash sources, token and data security, and store review readiness. You get Mobile App Dev Deliverables you can act on: findings ranked by severity, an estimate against each, and an honest call when the answer is a rewrite. 🛠 Full stack developer and Web developer work under the app The API, database and integrations are mine too: Node.js, REST, GraphQL, Firebase, Supabase, React on the web side. You hire 1 person instead of a Mobile App Developer plus a Full stack developer plus a Web developer, so the app never waits on someone else to finish an endpoint. 🇺🇦 Mobile app developer ukraine, 2 hour first response I work from Dnipro, so a mobile app developer ukraine search lands on my real location. Full overlap with Europe, 6 to 7 hours with US East, 2 hour reply. 🎯 8 industries, 1 of them past 50M downloads Social at scale: Chingari past 50M+ downloads.
