👋 I am Aleksandr. 15 years in Xcode and Android Studio, 100+ apps shipped, and I still like the moment a build first runs on a real phone.

I am a Mobile App Developer and CTO-level engineer, 15+ years, 100+ shipped apps, 109 closed contracts here. Native iOS in Swift, native Android in Kotlin, cross-platform Flutter and React native, plus the backend.
📱 Mobile app developer 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 you an app nobody can extend. 1 change on the last build, startup work moved off the network path, moved 2 metrics: cold start down, day-1 activation up. I write the app and the API under it, then hand over code your team can pick up without a rewrite.
🍎 Ios developer and Swift ios developer, 3 Apple platforms
As an Ios developer I build native Swift and SwiftUI apps for iPhone, iPad and Mac, 3 platforms, 1 codebase. A Swift ios developer earns the fee at App Store review: privacy manifests, permissions, in-app purchase rules, and the 4 rejection reasons behind most first failures. Your Ios app clears review as a launch date, not as a gamble. Your Ios app clears review as a launch date, not as a gamble.
🤖 Android developer, Android kotlin, Android developer kotlin, 3 device classes
As an Android developer I build native Kotlin apps with Jetpack Compose, phone to foldable. Android kotlin work means Play policy, background limits and 3 device classes that break layouts drawn at 1 width. 2 vitals thresholds decide your listing, ANR and crash rate, and reworking background sync on the last build brought ANR back under both. An Android developer kotlin project ships with the release pipeline configured, not as a zip file.
🔀 Flutter developer and React native, 1 codebase, 2 stores
As a Flutter developer I ship 1 codebase to both stores when 2 native builds are not worth it, and I say which case yours is. On the last one that decision cut the build budget roughly in half against two native apps. React native the same. If your team works with a Flutter mobile app developer India based or anywhere else, my code is documented for handover.
Aleksandr V. earns an estimated $13k/mo. That's 9.1× the typical freelancer and more than 99.94% of everyone we track.
🧠 Ai mobile app developer, 1 cost model before the build
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. 1 rule holds: I model the running cost per 1,000 users before we build, because AI features fail on the invoice sooner than on the code. Caching, prompt trimming, and a cheaper model for routine calls are the 3 levers, and on the last product they took the monthly bill down sharply.
🔎 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, real crash sources, security around tokens and stored data, and store review readiness. You get findings ranked by severity with an estimate against each, including the cases where the answer is a rewrite. 6 areas, findings ranked by severity, an estimate against each, and on the last audit most of the crashes traced back to a handful of those 6.
🛠 Full stack developer work under the app, 1 person instead of 3
The API, database and integrations are mine too: Node.js, REST and GraphQL, Firebase, Supabase. You hire 1 person instead of a Mobile App Developer plus a Full stack developer plus a Web developer, and the Web developer part of the job stops being a scheduling problem: the app never waits on someone else to finish an endpoint.
🇺🇦 Mobile app developer ukraine, 1 timezone question answered
I work from Dnipro, so a mobile app developer ukraine search lands on my actual location. Full overlap with Europe, 6 to 7 hours with US East, 2 hour first response.

⚙️ How I work as your Mobile App Developer, 3 commitments
Architecture and stack recommendation in the first conversation. Delivery in demo-able increments. Code your future team can read: 109 closed contracts here, several running for years on one product. React on the web side and React native on mobile share the same reasoning: pick the boring option that survives handover.
