Have a startup idea that needs to become a real app — fast?
Most developers build what you describe. I build what your business actually needs.
I’m Yash Gupta — Top Rated Flutter & AI App Developer with 6+ years of experience and $40K+ earned on Upwork. But here’s what makes me different from every other developer on this platform:
I’m also a founder.
I’ve built and launched my own apps — a barter marketplace, a smart trading alert platform, and a SaaS product — from zero to real users. That means when you hire me, you’re not just getting a coder. You’re getting someone who thinks about retention, user experience, and business growth while writing every line of code.
🏆 By The Numbers:
→ 50+ apps delivered across iOS & Android
→ 93% Job Success Score | Top Rated Badge
→ 52 completed contracts | 1,000+ hours logged
→ Clients from US, UK & Australia
🚀 What I Build Best:
✔ AI-powered mobile apps & ChatGPT integrations
✔ Flutter & React Native cross-platform apps
✔ Startup MVPs — idea to App Store in weeks
✔ SaaS platforms with subscription & billing
✔ Fintech, trading & investment apps
✔ Marketplace & ecommerce platforms
✔ Real-time chat & social networking apps
✔ On-demand & food delivery platforms
⚡ Tech Stack:
Flutter | React Native | Firebase | Supabase | Node.js | REST APIs | GraphQL | ChatGPT API | Stripe | Push Notifications | Maps & Geolocation | CI/CD | App Store & Play Store Deployment
🌟 Projects I’ve Shipped:
• BlinkX – Stock Trading & Demat App
• TradeBeep – Smart Trading Alert Platform (my own product)
• Panda Chat – Real-time Social Chat App
• FarmersKart – Grocery Ecommerce Platform
• SnapToLet – Rental Property Finder App
• Let’s Barter – Barter Marketplace App (my own product)
✨ Working With Me Means:
✅ Reply within hours — not days
✅ Weekly progress updates — no ghosting
✅ Clean, scalable architecture from day one
✅ Honest feedback if your idea needs rethinking
✅ Full support from concept to App Store launch
📩 Ready to build?
Send me your idea — even if it’s just rough notes. I’ll give you an honest assessment, a clear roadmap, and a realistic budget. No fluff, no overselling.
Let’s build something people actually use.

👋 Hi, I’m Dmytro - a Full Stack Developer, Mobile App Developer, and founder of Inmost. Together with my engineering team, I help startups and companies build production-ready web and mobile products using React Native, React, Node.js, iOS, Android, AWS, Firebase, BLE, and IoT integrations.
If you need a Full Stack Developer who can build more than a website, or a Mobile App Developer who can build more than app screens, we can help with the full product layer: frontend, backend, mobile apps, APIs, databases, cloud infrastructure, QA, and scalable architecture.
We are a Full Stack Developer and Mobile App Developer team with 50+ delivered web and mobile projects, 6,000+ engineering hours, 20+ React Native mobile applications, 15+ native iOS Swift production apps, and 20+ MVP projects for startups.
We build reliable software products, not just code: web apps, mobile apps, SaaS platforms, admin dashboards, backend APIs, cloud infrastructure, real-time systems, BLE apps, IoT mobile applications, wearables, and connected device applications.
Our engineering process is built around quality, structure, and speed. We use AI-assisted engineering workflows to accelerate planning, development, testing, documentation, and delivery. But AI never replaces engineering judgment: architecture, code review, QA, testing, and production releases stay under experienced engineers’ responsibility.
What we build:
⚙️ Full Stack Development
As a Full Stack Developer team, we build complete products from frontend to backend. Our full stack development work includes React development, Node.js development, backend development, REST API development, SaaS platforms, web applications, admin panels, dashboards, authentication, payments, databases, cloud infrastructure, and scalable systems.
🌐 Web App Development
We build web applications for startups and companies that need reliable and easy-to-maintain products. Our web app development experience includes SaaS development, marketplace platforms, CRM systems, internal tools, admin dashboards, customer portals, real-time web applications, and backend-connected platforms.
⚛️ React & Node.js Development
If you need a Full Stack Developer for React, Node.js, TypeScript, PostgreSQL, MySQL, Firebase, or AWS, we can support both frontend and backend development. Our Node.js development experience includes backend APIs, REST API development, third-party integrations, payment systems, real-time features, cloud services, and scalable backend architecture.
📱 Mobile App Development
As a Mobile App Developer team, we build iOS and Android applications for startups and companies that need production-ready mobile products. Our mobile app development work includes MVP mobile apps, enterprise mobile systems, SaaS mobile apps, healthcare applications, marketplace apps, real-time mobile platforms, and cross-platform mobile development.
⚛️ React Native Development
We have delivered 20+ React Native mobile applications for iOS and Android. If you need a Mobile App Developer for React Native development, we can handle cross-platform development, backend-to-mobile integration, API-driven mobile architecture, Firebase integration, push notifications, payments, chat, video, real-time updates, and scalable MVP development.
🍏 iOS & Android App Development
Our Mobile App Developer team has strong iOS app development and Android app development experience, including 15+ iOS Swift production applications. We work with Swift, Kotlin, Java, API integration, authentication, in-app purchases, push notifications, mobile app testing, performance optimization, and App Store / Google Play-ready products.
📡 BLE, IoT & Wearables
One of our strongest technical areas is BLE and IoT mobile app development. We build mobile applications connected to hardware devices, sensors, wearables, and cloud platforms: Bluetooth Low Energy apps, BLE iOS apps, BLE Android apps, AWS IoT Core, MQTT, wearable app development, real-time device communication, sensor data streaming, and IoT device integration.
☁️ Backend, API & Cloud Architecture
A serious web or mobile product needs more than a frontend. As a Full Stack Developer and Mobile App Developer partner, we support products with backend development, API development, REST API integration, PostgreSQL, MySQL, Firebase, AWS, AWS IoT Core, real-time systems, and scalable architecture.
Clients hire us when they need a Full Stack Developer or Mobile App Developer who can build reliable web apps, mobile apps, SaaS platforms, React Native products, Node.js backends, admin dashboards, API-driven platforms, BLE apps, IoT mobile applications, and connected device systems.
If you are looking for a Full Stack Developer or Mobile App Developer to build or scale your product, let’s discuss how to turn it into reliable, production-ready software.

✅ Upwork Top Rated Plus & Verified Mobile App Developer
AI-Powered React Native & Flutter Developer | BLE Hardware + LLM Integration Specialist
Most mobile apps fail not because of bad code but because the developer couldn't handle what came after the screens. BLE sync breaks. The AI feature needs to talk to real hardware. The App Store review gets rejected. That's exactly the gap I've built my career around closing.
I'm Muhammad. 7 years building production mobile apps, $100K+ earned across 38 contracts on Upwork, and a Top Rated Plus track record that speaks for itself.
WHAT I ACTUALLY BUILD:
✅ React Native apps, from blank repo to App Store, end-to-end
✅ Flutter apps with BLE/NFC hardware integration (custom protocols, firmware handshake, real-time sync)
✅ AI-powered mobile features with OpenAI, Claude, Gemini APIs wired directly into native UX (not bolted on top)
✅ LLM + RAG pipelines built into mobile, not web wrappers
✅ Node.js backends designed for mobile clients
✅ Native iOS (Swift) when cross-platform is the wrong call
SHIPPED & VERIFIED:
• Medalite: Flutter app with custom BLE light therapy mask. Real-time hardware sync, firmware handshake. $12,300. ⭐ 5 stars.
• Chaser: Long-term React Native engagement platform. $21K+. Client kept building.
• iOS Teleprompter App: High-complexity Swift + React Native, real-time text rendering. $6,500. ⭐ 5 stars.
• AI Analytics for iOS: LLM-powered insights wired into a native iOS app. 135 hours. ⭐ 5 stars.
• Audio App MVP: Full Flutter build. Client returned for more.
Industries: Healthcare · Fitness · Fintech · IoT · AI/ML
I respond within 10 to 15 minutes. I don't ghost milestones.
If the scope is clear, send it and I'll give you a number.
If it's complex, I'll ask the right questions and we'll figure it out together.

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.
A SaaS mobile product with a Node.js, AWS, or Firebase infrastructure.
An AI-powered mobile experience designed by a top-tier mobile app developer.
A wellness or health tech application (deep niche domain experience).
📱 Core Summary of Expertise
✔️ Mobile App Development: From wireframes to 100K+ active users and global scaling.
✔️ Mobile App Developer: Specialist in React Native, Expo, and performance optimization.
✔️ iOS Android Developer: Full-stack integration with Node.js, AWS, Firebase, and Supabase.
✔️ Web & AI Development: Next.js architecture, REST/GraphQL APIs, and LLM integration.
