$200K+ earned | 345+ apps shipped | App Store submission expert | Top Rated | 8+ years
Senior Mobile App Developer specializing in iOS & Android apps built with Flutter, React Native, Swift, and Kotlin — now AI-accelerated with Cursor AI, Lovable, Replit, and Base44 for 3x faster MVP delivery.
Over the past eight years I've shipped 345+ production apps on the App Store and Google Play — native iOS, native Android, and cross-platform builds in Flutter and React Native. Today, I combine that senior engineering foundation with modern AI development tools to deliver faster, cleaner, and more scalable mobile products than traditional workflows allow.
WHAT I BUILD
Native iOS applications — Swift, SwiftUI, Objective-C, Xcode
Native Android applications — Kotlin, Java, Android Studio
Cross-platform applications — Flutter, Dart, React Native, Expo
AI-integrated mobile apps — OpenAI, Claude, on-device ML, LLM workflows
Full-stack mobile products — frontend, backend, auth, payments, deployment
MVP sprints — idea to working app in 3 to 4 weeks
Long-term engineering partnerships — v2, scaling, refactors, ongoing features
WHY CLIENTS HIRE ME
A proven track record. $200K+ earned on Upwork, 345+ delivered projects,
and maintained across 622+ logged hours. Top Rated status and Google Certified Mobile Developer credentials. Clear communication. Daily updates, weekly demos, honest timelines. No
surprises, no missed deadlines, no vague status reports.
Full ownership. I don't just take orders. I'll push back on bad specs,
suggest better approaches, and treat your product like my own.
AI-ACCELERATED DEVELOPMENT
Most freelancers marketing "vibe coding" generate fragile AI-written code that breaks the moment real users arrive. I take the opposite approach: senior engineering decisions, AI-accelerated execution. The tools speed me up; the quality comes from eight years of real mobile engineering.
Cursor AI — AI-native IDE for multi-file refactors, test generation, and pair-programming on complex Flutter and React Native codebases.
Lovable — Rapid MVP prototyping for founders validating ideas, then graduated to production-grade Flutter or React Native builds with proper architecture.
Replit — Cloud-based iteration, live collaboration, and instant deploys for client demos and investor-ready prototypes.
Base44 — Full-stack app generation with built-in authentication, database, and hosting. Ideal for internal tools, admin dashboards, and SaaS MVPs.
Bolt.new, v0, Claude Code, Windsurf — additional tools in my stack for the right use case.
The outcome: idea to validated, shippable product in 3 to 4 weeks instead of 3 months, built on architecture that actually scales past v1.
TECH STACK
Mobile Flutter, React Native, Swift, SwiftUI, Kotlin, Java, Dart
AI tooling Cursor, Lovable, Replit, Base44, Bolt.new, v0, Claude Code
Backend Firebase, Supabase, Node.js, REST, GraphQL
Databases Firestore, SQLite, Realm, MongoDB, MySQL, PostgreSQL
Cloud Firebase, AWS (S3, EC2, Lambda), Google Cloud
Integrations Stripe, PayPal, OAuth, Google Maps, Push Notifications, In-App Purchases
AI & ML OpenAI, Claude API, on-device ML, LLM integrations
HOW WE WORK TOGETHER
Discovery — a free 30-minute call to scope your project properly and agree on whether I'm the right fit.
Planning — clear milestones, fixed timeline, agreed deliverables. No vague "we'll figure it out" contracts.
Build — daily progress updates, weekly demos so you see real work, not status reports.
Launch — App Store and Play Store submission, deployment, and handoff with full documentation.
Support — 30 days of free post-launch support on every project.
Whether you're a founder validating an MVP, a startup scaling to v2, or an established business modernizing a mobile product, I can help you ship faster and better.
Send me a message with your idea — even a rough one — and I'll tell you how we can proceed further

I am always honest, so don't expect me to lie to you or to your customers. I believe successful collaboration depends on truth and effective communication.

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.
