Hey! I'm Mykyta, a mobile app developer, React Native specialist, and full-stack engineer with 10+ years of experience and 32 successfully released apps. My core specialty is end-to-end mobile app development and building high-performance applications as a dedicated ios android developer for wellness, startups, and SaaS businesses. I've hit "App of the Day" on the App Store, helped a startup secure $750k, scaled products to 100K+ active users, and delivered 30%+ growth in user retention. That's a proven track record. 🏄 React Native & Cross-Platform Expertise As a battle-tested mobile app developer, I build cross-platform applications that feel truly native. For comprehensive mobile app development, whether you're comparing React Native vs Flutter or need an expert perspective to make the right choice, I help you select the exact stack that fits your business goals, timeline, and budget. As a versatile ios android developer, I ship apps across both ecosystems using React Native, Expo, TypeScript, and JavaScript, managing the pipeline from architecture to final App Store deployment. Every professional mobile app developer knows that seamless integration requires deep platform knowledge and clean memory management — that is exactly what I bring to the table. 💻 Full Stack & End-to-End Product Ownership I own the entire product lifecycle, providing full-cycle mobile app development from web dashboards to final deployment. When you hire an all-in-one ios android developer, you get native-level client performance backed by a scalable infrastructure: Mobile: React Native, Expo, TypeScript, JavaScript, Redux, GraphQL, Reanimated, Lottie. Backend & Cloud: Node.js, Nest.js, AWS (S3, EC2), Firebase, Supabase, PostgreSQL, MongoDB. APIs & DevOps: Stripe, PayPal, Segment, Appsflyer, Sentry, CI/CD pipelines, Docker, GitHub Actions. As a React/Next.js developer, I complement every mobile product with robust web frontends. Working as your trusted mobile app developer, I ensure you get one reliable partner for the full stack. 🤖 AI Features & MVP Launch AI is no longer optional. I build intelligent mobile features — custom LLM integrations, smart AI recommendation engines, and predictive UX. Having an expert in AI-native mobile app development on your team is a massive competitive advantage. As an innovative ios android developer, I blend AI with mobile performance seamlessly. I've built MVPs from zero to App Store deployment as a skilled ios android developer dozens of times. My optimized mobile app development process focuses on agile execution, rock-solid security, award-winning UI/UX, and long-term post-launch support from a reliable mobile app developer. I focus heavily on business metrics, helping founders achieve at least a 42% ROI on their mobile investment. 🎯 My Collaboration & Communication Philosophy A great app requires more than just clean code; it demands absolute transparency and alignment. I do not operate in a vacuum. When we work together, you get clear asynchronous updates, structured Slack or Microsoft Teams communication, and weekly video syncs with measurable milestones. I deeply understand business priorities, constraints, and the critical importance of keeping deadlines, making our partnership stress-free and highly predictable from day one. ⚙️ Scalable Architecture & Clean Code Approach Production-ready apps require careful planning. I focus on creating clean, modular, and maintainable codebases using cutting-edge design patterns. This means your application will be ready for rapid feature additions, team scaling, and heavy traffic loads without requiring a complete rewrite in six months. I prevent technical debt early by implementing strict TypeScript typing, optimized component re-rendering, and robust offline data caching mechanisms right from the start. ⚙️ Who I Work With I'm a great fit if you're looking for an experienced ios android developer to build: A React Native cross-platform app for iOS & Android with complex business logic.

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
