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. 🔑 Areas I cover: Flutter App Development • Mobile App Development • AI Development • Flutter developer • Flutter app developer • Mobile app developer • Cross-platform app development • React Native developer • iOS app development (Swift) • Android app development (Kotlin) • Full stack developer • Web developer • Web design • API development • REST API integration • Node.js • Python • FastAPI • Firebase • AI agents • AI assistants • image recognition • workflow automation • MVP development • App Store & Google Play deployment • mental health apps • productivity apps • social & audio apps

Hi, I'm Eldar, your future technical partner here on the Upwork :) ⚡ AI-streamlined delivery: expect a working MVP in 1–2 weeks. I'm a senior Flutter Developer and full stack developer at Dreambit with 10+ years in full-cycle Mobile App Development, and I use AI across the whole workflow — planning, code generation, testing, and review — to compress timelines where that is possible without cutting corners. I've delivered 50+ apps with 100K+ downloads and a consistent 5-star rating, working with startups, agencies, and enterprise clients to plan, build, and scale products that thrive in the real world, going well beyond the traditional mobile app developer role. As a dedicated flutter app developer, I ship iOS Development, Android App Development, and Web from a single Flutter Stack + Dart codebase — one source of truth running natively on every smartphone, which is how I keep delivery fast and maintenance low across those 50+ launches. Need to move quickly on an MVP? I work as a flutterflow developer to validate ideas in days. Need depth? I hand-write flutter for complex products and build rock-solid flutter firebase backends (auth, Firestore, Cloud Functions, push) — including offline-first sync engines with conflict resolution, payments, and real-time sessions that hold up at 100K+ users. I'm also a seasoned React Native Developer with deep React experience. If your product runs on react native mobile, I cover react native expo and bare workflows, native react native ios builds, polished Android UI, and fluid 60fps react native animation. Plenty of clients arrive needing mobile app development react native support and stay for a cleaner, unified foundation — whether you're hiring your first react developer, replacing a previous react native developer, or migrating off one entirely, I make the transition painless. Beyond the app I work as a web developer, building secure APIs and admin panels with Node.js, NestJS, TypeScript, and Python, integrating cleanly with whatever you already run — including a legacy Laravel backend — so your mobile app and web dashboard stay in sync. My stack: Flutter, Dart, React Native, Firebase, Node.js, TypeScript, JavaScript, Swift, Kotlin, Java, Python. I also add AI features that feel native to the product — orchestrating LLM workflows, intelligent agents, and "chat with your data" setups with guardrails and cost control, so you get real utility, not buzzwords. As a senior mobile application developer, I own the full lifecycle: thoughtful mobile app design and UI/UX (a big reason behind that 5-star rating), plus practical input on mobile app marketing and store optimization so your launch actually lands. Industries: Healthcare, Fintech, Social & dating, Meditation, Astrology, and E-commerce — including secure, regulated environments. We handle compliance-heavy projects and stay current with EU and US rules, and we're registered in both the US and EU, so billing and invoices are never a problem. You can check our quality right now in the stores — this year we've already shipped 7 apps (15 last year), and "release" never means we walk away: many products run on a 6-month roadmap with updates every 2–4 weeks. I act as your partner across the whole journey — consultation, technical decisions, design, or publishing help — you can count on me and my team. We don't just deliver the project; we flag the risks and find the fastest path to your ROI. And if you need help with an existing app — a rescue, or lifting conversion and retention — my experience is fully at your disposal. Dreambit cares — whether you're non-technical, just starting your development journey, scaling an existing business or app, or you need serious expertise in mobile development and AI integration for your product or a wider service offering. If what you're really after is reliable, honest work here on Upwork, you've found the right team. Why Dreambit: ✅ Total Ownership from Day One — you hold the keys to all source code, repositories, and accounts, and always see exactly what you're paying for through clean, meaningful commits. ✅ Guaranteed Pricing & "No Demo, No Invoice" — we never exceed our pessimistic estimates unless scope changes; milestone payments are strictly tied to live demos of working features. ✅ Transparent Team, No Subcontractor Secrets — the team you meet is the team that builds your product; direct access to your developers, no bait-and-switch, no unvetted offshore handoffs. ✅ Extreme Ownership & Weekly Demos — no finger-pointing, no hiding from calls; proactive weekly updates, and if a challenge arises, we bring solutions, not excuses. ✅ Built-in QA & Warranty — built to scale, not to break; work is "done" only after rigorous UAT, backed by a one-month bug-free warranty on every invoice. 📩 Message me for a free 30–60 min consultation and I'll share my Upwork scheduler link

I build Apple Watch app, watchOS, and Swift-based mobile products for health, fitness, wellness, healthcare, biometric tracking, and wearable technology companies that need a stable native iOS experience, not just a basic mobile screen. If you need an Apple Watch app for an existing iOS app, a new watchOS product from scratch, or an iOS watch app connected to HealthKit, wearable data, haptics, activity tracking, workout flows, or real-time user feedback, I can help you design, build, and ship it with a clean native architecture. I specialize in Apple Watch app development, watchOS development, Swift development, iOS Development, and Mobile App Development for products where reliability, performance, and user experience matter. My work is focused on native iOS, Apple Watch Application development, watchOS, Swift, SwiftUI, WatchKit, HealthKit, UIKit, Apple Xcode, iOS SDK, Firebase, API Integration, In-App Purchases, and Clean Architecture. For Apple Watch app projects, I can help with: • Apple Watch app development from scratch • watchOS app development for an existing iOS app • iOS watch app architecture and implementation • Swift and SwiftUI development • WatchKit-based Apple Watch Application features • HealthKit integration and HealthKit SwiftUI flows • health, fitness, sleep, activity, and wellness tracking • haptics, notifications, session tracking, and real-time user feedback • wearable integration and smart watch product logic • Firebase, API Integration, data sync, and backend-connected mobile features • App Store-ready iOS and watchOS builds I have 8+ years of experience in native Mobile App Development, including Swift, iOS, iOS Development, Kotlin, Firebase, API Integration, and healthcare/wellness products. I do not approach Apple Watch app development as a simple add-on screen. A good Apple Watch app needs fast interactions, clear watchOS UX, stable background behavior, thoughtful HealthKit integration, reliable sync with the iOS app, and clean Swift architecture. Relevant work includes BlueRoom, an award-winning XR training platform and Garmin Health Awards 2023 winner. BlueRoom used wearable integration, biometric tracking, real-time physiological monitoring, stress response tracking, performance analytics, and real-time data synchronization. While this was not an Apple Watch-only product, the experience is highly relevant to Apple Watch app, smart watch, wearable, biometric, and HealthKit-style products that depend on accurate real-time user data. Another relevant project is MedNAIS, a native healthcare platform for hospitals, labs, and clinics. It included smartphone, tablet, and smartwatch workflows, SOP management, hands-free guidance, roles, permissions, workflows, KPI dashboards, and healthcare team productivity tools. This experience is directly useful for Apple Watch app and watchOS products in healthcare, where smartwatch interactions, iOS watch app flows, and wearable use cases need to be simple, reliable, and useful in real working environments. I also worked on Go Polar, a native Swift iOS wellness app for cold plunge and sauna tracking. The app includes session workflow tracking, custom UI, goal-based time and temperature logic, stats, activity sync, sound controls, and haptics. This is relevant for Apple Watch app, watchOS, HealthKit, health app development, fitness app development, wellness tracking, and wearable product experiences where users need fast, clear, and consistent tracking. If you are building an Apple Watch app, improving a watchOS app, adding an iOS watch app to your current product, integrating HealthKit, building HealthKit SwiftUI screens, or creating a wearable / smart watch experience around health, fitness, sleep, activity, or healthcare workflows, I can help you turn the idea into a stable native product. My focus is Apple Watch app development, watchOS development, Swift development, SwiftUI, WatchKit, HealthKit, iOS Development, Mobile App Development, Apple Watch Application features, API Integration, Firebase, In-App Purchases, Mobile App Design, App Development, and Clean Architecture. I can join at any stage: app consultation, technical planning, Apple Watch app architecture, watchOS feature development, Swift code implementation, iOS watch app integration, HealthKit integration, wearable data sync, MVP development, existing app improvement, bug fixing, or App Store preparation. If your product needs an Apple Watch app that works smoothly with your iOS app, a watchOS experience that feels native, or a Swift-based health, fitness, wellness, or healthcare mobile app with wearable logic, I can help you build it properly. 📩 READY TO START ASAP
