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.

☁️ AWS Cloud Storage
🧩 Clean Architecture & State Management
🛠 App Deployment & Maintenance
I’m comfortable working independently, collaborating with teams, or building apps from scratch from idea to production.
One thing I genuinely enjoy about this work is solving problems and turning ideas into real products people can actually use. I also pay a lot of attention to UI details and user experience because I believe a good app should feel smooth, clear, and reliable.
Outside of coding, I enjoy photography, videography, learning new things, and spending time with my plants 🏡👩🌾
