About this gig
Looking for a developer to turn your app idea into a real, production-ready product?
I build modern iOS & Android applications with React Native, from MVPs and business apps to AI-powered mobile products.
Services:
Custom React Native / Expo apps
AI-powered mobile apps & chatbots
OpenAI, Claude & Gemini integration
AI agents, tool calling & RAG
REST API & custom backend integration
Firebase / Supabase / MongoDB
Authentication, subscriptions & payments
WebView & website-to-mobile apps
Admin panels & business systems
App Store & Google Play deployment
Tech Stack: React Native, Expo, React, Next.js, TypeScript, Node.js, Express, Supabase, Firebase, MongoDB, Redis, AWS, Docker and more.
I focus on clean, maintainable and scalable solutions rather than templates or no-code shortcuts. I can handle both the mobile app and the backend, helping you go from idea to production.
Whether you're launching an MVP, startup, SaaS, business app or AI product, send me your idea and let's build it.

FAQ
Can you integrate APIs and third-party services?
Yes. I can integrate REST APIs and third-party services such as payment systems, authentication providers, AI APIs, maps, notifications, analytics, and other external services.
Can you add subscriptions or in-app purchases?
Yes. I can implement mobile subscriptions and in-app purchases, including solutions using RevenueCat and Google Play subscriptions.
Can you publish the app to the App Store and Google Play?
Yes. I can help prepare and configure the application for production release and guide you through the App Store and Google Play submission process.
I only have an idea. Can you still build the app?
Absolutely. You don't need to have a complete technical specification. You can share your idea, and we can define the features, architecture, and development scope together.
Can you work with my existing application and add new features?
Yes. I can work with an existing React Native, Expo, React, Next.js, or backend project to fix bugs, improve performance, integrate new features, or extend its functionality.
Do you provide source code?
Yes. The source code is provided according to the package and project agreement.
Can you build an MVP for my startup?
Yes. I can help transform your idea into a functional MVP with the essential features needed for testing and launching your product.
What do you need from me before starting?
Ideally, I need your app idea, required features, preferred design or references, and any existing assets or backend/API information. If you don't have everything prepared, that's okay—we can define the requirements together before development.
