🏆 𝐓𝐨𝐩 𝐑𝐚𝐭𝐞𝐝 𝐏𝐥𝐮𝐬 𝐨𝐧 𝐔𝐩𝐰𝐨𝐫𝐤 | 💯 100% 𝐉𝐨𝐛 𝐒𝐮𝐜𝐜𝐞𝐬𝐬 | ⭐️ 11,000+ 𝐇𝐨𝐮𝐫𝐬 𝐁𝐢𝐥𝐥𝐞𝐝 | 📲 400+ 𝐏𝐫𝐨𝐣𝐞𝐜𝐭𝐬 𝐃𝐞𝐥𝐢𝐯𝐞𝐫𝐞𝐝 | 🚀 14𝐌+ 𝐃𝐨𝐰𝐧𝐥𝐨𝐚𝐝𝐬 | 👥 900𝐊+ 𝐌𝐨𝐧𝐭𝐡𝐥𝐲 𝐀𝐜𝐭𝐢𝐯𝐞 𝐔𝐬𝐞𝐫𝐬 | 4.8⭐️ 𝐀𝐯𝐠 𝐀𝐩𝐩 𝐒𝐭𝐨𝐫𝐞 𝐑𝐚𝐭𝐢𝐧𝐠 | 💰 $5𝐌+ 𝐑𝐚𝐢𝐬𝐞𝐝 𝐛𝐲 𝐂𝐥𝐢𝐞𝐧𝐭 𝐏𝐫𝐨𝐝𝐮𝐜𝐭𝐬
❗️ UpLife hit 1M+ users and a 4.8⭐️ rating after we took it from idea to scale with Flutter App Development and AI Development. Parlor scaled to 10M+ users. GoFrendly raised $2.88M. This is what the right Mobile App Development partner converts into - real traction, real revenue, real users.
👋 I'm Oleg - founder of Olearis (mobile dev studio) and a hands-on Mobile App Developer. I build apps that actually ship, get used, and survive after launch - Flutter and React Native, usually with AI agents inside.
I'm a founder and mobile product engineer, not just a coder for hire. I've launched my own apps, so I understand the founder side: budget pressure, unclear scope, investor expectations, App Store deadlines. I'll tell you when something is a bad idea before it burns your budget.
🎯 Where I create the most value:
▪️ Flutter App Development, done right — As a Flutter developer and Flutter app developer I ship clean architecture, smooth 60 FPS UI, native integrations, payments, push, analytics, and full App Store / Google Play launch support. Cross-platform Mobile App Development means you ship once instead of paying to build the same app twice. When a product needs native depth, I also work in Swift (iOS) and Kotlin (Android).
▪️ AI Development that earns its place — AI assistants, smart onboarding, personalization, recommendations, image recognition, and context-aware journeys. I build practical AI Development features like document processing and job application automation. A good AI agent is often the reason users come back — not just a trendy add-on.
▪️ Full-stack support — as a full stack developer I cover Node.js, Python, FastAPI, Firebase, REST APIs, and API development, plus cloud functions and admin dashboards. As a web developer I also handle the surrounding web design and panels, so there are fewer handoffs and faster decisions.
🧠 Industries where I go deep: Mental health & wellness apps, where trust, privacy, and calm UX matter as much as code and productivity apps with habit loops, reminders, streaks, and smart automations.
📲 A few products I've shipped as a mobile app developer:
✔️ UpLife — mental health app with an AI assistant & therapy recommendations. 1M+ users, 4.8⭐️
✔️ Parlor — social audio platform scaled to 12M+ users
✔️ GoFrendly — social network for women. 450K+ users, $2.88M raised
✔️ Notate — secure productivity app trusted by Bank of America, Citibank & 80+ companies
✔️ Mila Cares — connected HEPA air purifier app. 50K+ users, $1.58M raised
✔️ Fillrr — AI-powered document app, 4.9⭐️
✔️ Photofy — content creation app, 100K+ users, 4.9⭐️
Whether it's a two-week MVP or a long-term Mobile App Development build, I care about shipping the right thing - not just more things. ⚡️ I respond in under 10 minutes during working hours.
If you need Flutter App Development, React Native, full stack developer support, or AI Development from someone who has shipped real products at scale - send me the details and I'll tell you honestly what it'll take.
🤝 Why founders keep coming back: I treat your budget like my own and your deadline like a launch I'm personally on the hook for. As a Mobile App Developer and Flutter developer I don't disappear after the App Store approval - I stick around for the messy part: real users, real reviews, real iteration. Most of my work is repeat clients and referrals, because shipping once is easy and shipping something that keeps working is the hard part. If you've been burned by a flutter developer or mobile app developer who delivered a demo and vanished, that's exactly the gap I fill.
🌍 I work with founders, startups, and product teams worldwide - from a first MVP to scaling an app past 1M users. Clear communication, fast replies, honest scope estimates, and no surprises on the invoice. Whether you're validating an idea or rescuing a stalled build, I'll bring the same product-first thinking that took UpLife, Parlor, and GoFrendly to scale.

Are you tired of maintaining two separate codebases for Android and iOS?
I help startups and businesses ship both platforms faster with a single,
shared Kotlin codebase using Kotlin Multiplatform (KMP) and Compose
Multiplatform (CMP).
While most developers build for one platform, I specialize in the modern
cross-platform stack that reduces your development cost by up to 50% — without
sacrificing native performance or user experience.
────────────────────────────────────────────────────────────
🔧 WHAT I BUILD
────────────────────────────────────────────────────────────
✅ Cross-platform apps with shared UI using Compose Multiplatform (CMP)
✅ Shared business logic across Android & iOS with KMP
✅ Native Android apps with Jetpack Compose & Clean Architecture
✅ Migrating existing Android apps to Kotlin Multiplatform
✅ In-App Purchases, subscriptions & RevenueCat / Play Billing integration
✅ Push notifications (FCM / APNs), WebSockets & background processing
✅ REST API & WebSocket integration with Ktor
✅ Local caching with SQLDelight / Room KMP
✅ PDF generation, file handling, document upload & viewers
────────────────────────────────────────────────────────────
⚙️ TECH STACK
────────────────────────────────────────────────────────────
Cross-Platform : Kotlin Multiplatform (KMP), Compose Multiplatform (CMP)
Android : Jetpack Compose, MVVM, Clean Architecture, Coroutines, Flow
iOS : SwiftUI interop, Xcode, CocoaPods / SPM integration
Networking : Ktor, Retrofit, WebSockets, REST APIs
Storage : SQLDelight, Room KMP, DataStore
DI : Koin, Hilt
CI/CD : GitHub Actions, Fastlane, App Store Connect, Play Console
Other : Firebase, OneSignal, RevenueCat, Coil, Kotlin Serialization
────────────────────────────────────────────────────────────
💼 REAL-WORLD EXPERIENCE
────────────────────────────────────────────────────────────
I've shipped production KMP apps including AI-powered tools that run
identically on Android and iOS with shared networking, business logic,
background task processing, PDF exports, and subscription flows.
I understand both platforms deeply: Android lifecycle, iOS Info.plist
entitlements, App Store review guidelines, and Google Play publishing.
────────────────────────────────────────────────────────────
✅ WHY CLIENTS CHOOSE ME
────────────────────────────────────────────────────────────
→ One developer. Both platforms. One codebase.
→ Senior-level experience — no hand-holding needed
→ Clear communication and on-time delivery
→ I write code you can maintain, not spaghetti you'll regret
If you want a developer who truly understands Kotlin Multiplatform and
Compose Multiplatform not just someone who Googled it — let's talk.
Send me a message describing your project and I'll respond within a few hours.

Struggling to find a mobile developer who ships production-ready apps — not just prototypes?
I build Native Android, Native iOS, and React Native applications that hold up under real-world pressure: high traffic, unreliable networks, hardware integrations, and tight deadlines.
Most recently: I built and deployed a multi-terminal Android POS & Kiosk system that processed AUD 1.5M+ via Stripe across 100+ devices in 10 days at the Sydney Royal Easter Show 2025 — running reliably in poor network conditions throughout.
That's the standard I hold myself to on every project.
WHAT I BUILD
🔹 Android & iOS Apps — Kotlin, Swift, Jetpack Compose, Clean Architecture, MVVM
🔹 React Native — Production apps with analytics, CI/CD, auth integrations and more
🔹 Payment & Hardware Systems — Stripe Terminal, RFID, BLE, kiosk, POS
🔹 Backend — Node.js, NestJS, REST APIs
🔹 Offline-First Systems — Sync, retry logic, transaction integrity, fault tolerance
WHERE I'VE DELIVERED
💳 Fintech & payment platforms
🛍️ E-commerce & booking apps
🎪 High-traffic event platforms (agenda, networking, AR navigation)
🏭 IoT & hardware-integrated mobile systems
🔐 Access control & identity systems
WHY CLIENTS REHIRE ME
I don't hand off prototypes and disappear. I think in systems, considering edge cases, failure modes, and long-term maintainability before writing line one of code. You get an engineer who cares whether your product actually works in production.
Independently vetted: accepted into an elite global engineering network with a sub-3% acceptance rate
Average response time under 2 hours
Delivered across US, EU, and UAE clients in remote cross-functional teams
If your project involves real complexity, payments, hardware, offline logic, scale, or a hard deadline, let's talk. Send me a message describing your project and I'll respond within a few hours with honest thoughts on fit.
